The different types are listed on the lubricant plate of the machine. In converter operation an insulated bearing is usually installed on the non-drive end. The following rolling-contact bearing variants are available: Table 3-3 Rolling-contact bearing variants Version Rolling-contact bearing Horizontal type of construction, coupling output Drive end: Deep-groove ball bearing as a fixed bearing Horizontal type of construction, for increased transverse forces e.g. in the case of belt coupling Drive end: Cylindrical-roller bearing as a floating bearing Non-drive end: Deep-groove ball bearing as a floating bearing with axial compression springs Non-drive end: Deep-groove ball bearing as a fixed bearing Vertical type of construction, Drive end: Deep-groove ball bearing as a fixed bearing shaft height 315, coupling output Non-drive end: Deep-groove ball bearing as a floating bearing with axial compression springs Vertical type of construction, shaft height 355 ... 450 Drive end: Pairing of angular-contact ball bearing / deep-groove ball bearing as a fixed bearing Non-drive end: Deep-groove ball bearing as a floating bearing with axial compression springs The standard version of the machine is not suitable for belt couplings. This can result in damage to the machine. Automatic regreasing system (option) The roller bearings are optionally equipped with an automatic regreasing system. The roller bearings are supplied with new grease portions by the regreasing system in parameterized time intervals. Rolling-contact bearing design for "Increased degree of protection" (option) Improved sealing of the bearing units to prevent dust and water from getting in can be achieved by positioning a grease chamber ahead of the actual bearing unit. Although the same grease is used in both cases for reasons of convenience, a distinction is made here between "lubricating grease" and "sealing grease" because of their different functions. Layout The spent lubricating grease collects in the space between the bearing housing and the outer bearing cap. The latter also forms the sealing grease chamber with the labyrinth sealing ring (optional). The second lubricating nipple containing the grease duct for pressing in the sealing grease is also located in the outer bearing cap. The chamber is sealed off from the space where the lubricating grease collects by a V-ring or a V-ring and felt ring combination which prevents the sealing grease in the chamber from penetrating into the lubricating grease collecting space. SIMOTICS FD 1LM1 Operating Instructions 01/2019 27 Description During operation, the sealing grease in the chamber slowly runs out via the labyrinth and seals it, additionally removing dust from inside and around the outside of the labyrinth ring.

Unpack the goods if the packaging is damaged. Correctly store the goods corresponding to the type. Repair any damage to the packaging before putting the equipment into storage insofar as this is necessary to ensure proper storage conditions. General instructions for storage Wherever possible, store the machine in a storage room. The place of storage must satisfy the following general conditions: Select a sufficiently sized dry and horizontal place of storage that is above flood level and free of vibration (veff 0.2 mm/s). - The place of storage must be well ventilated as well as free of dust and frost. Provide protection against extreme weather conditions. Ensure that the temperature remains stable in the range from 10 C to 50 C - or 50 F to 120 F. If there is a risk of condensation, the room temperature should be approx. 10 K above the outside temperature. The temperature should not fall below 20 C. - The relative humidity of the air should be less than 60%. - The floor of the place of storage must be sufficiently strong. The maximum permissible floor loading or storage compartment loading may not be exceeded. - The ambient air must not contain any harmful gases. Protect the machine from shocks and humidity. Position machines, devices and crates on pallets, wooden beams or foundations that protect them against rising damp and water. Ensure that the air circulation under the equipment is not impeded. - Place wooden spacer blocks between the covers and the machine. - Covers or tarpaulins must not trail on the floor around the machine. Storing outdoors When storing the machines outside, the storage location must comply with the following conditions: The ground must be sufficiently strong. Prevent the machine from sinking into the ground. Covers or tarpaulins used to protect the equipment against the weather must not make contact with the surfaces of the equipment. Otherwise air circulation under the stored items will be prevented. 40 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Preparations for use 4.18 Storage Protection against humidity If a dry storage space is not available, protect the machine as follows against humidity: Wrap the machine in humidity-absorbent material. Wrap the machine in plastic film: - Place a humidity meter inside the plastic film. - Place desiccant within the plastic film. - Pack the machine air-tight. Inspect the machine regularly. NOTICE Improper storage or transport Damage to bearings can result from improper storage or transport. On machines that have been supplied with a rotor shipping brace, secure the rotor as per the notes on transportation (Page 37). Protect the motor against strong radial shocks and vibration when storing, as the rotor shipping brace cannot completely absorb these forces. If the customer has already mounted parts, such as a coupling or belt pulley, the bearings can be damaged during transport. In this case, make sure that the customer uses a rotor locking device. Long-term storage If you are storing a machine for more than six months, you must check its condition every six months. Store the machine in accordance with the specifications in Section "Storage (Page 39)", and if possible, packed. Check the motor for damage. Carry out any necessary maintenance work. Make sure that the storage conditions are such that condensation cannot form in the motor. If the machine is not sealed in plastic film, continually and slightly heat the machine, e.g. with anti-condensation heating (if available), and ensure that the air circulates in the storage room. Storage for longer than three months Lubricate the machine after every two years of storage. 1. Unpack the machine. 2. Remove the rotor shipping brace, if one is being used. SIMOTICS FD 1LM1 Operating Instructions 01/2019 41 Preparations for use 4.18 Storage 3. When stored for longer than two years, lubricate with twice the grease quantity in accordance with the lubricant plate. This ensures that the grease is evenly distributed and covers all surfaces. Corrosion damage is avoided. NOTICE Damage to roller bearings Roller bearings can be damaged when kept in the same or almost the same position. Every three months, manually rotate the rotor through five revolutions. Make sure that the resting position of the roller bearings after the rotor has been turned is different from what it previously had been. Use the feather key as a reference point, if present. 4. Replace the corrosion protection. 5. Reattach the rotor shipping brace, if present. 6. Pack the machine again. 4.18.2 Storing the filter mats (option, air filter) Store the filter mats in a dry location, and ensure that they do not come into contact with the walls and floor. Leave the filter mats in their original packing until they are used. Condensation is not permissible where the filter mats are being stored. 4.18.3 Protection against corrosion If the machine is stored in dry conditions, then apply the subsequently listed anti-corrosion measures: Storage up to six months: Apply a coat of corrosion protective compound to all accessible bare metal parts such as the exposed shaft extension, flange or machine feet. Storage for longer than six months: Apply a coat of long-term anti-corrosion agent to all accessible bare parts. Inspect the machine regularly and if necessary, apply an additional coating of corrosion protection. Document all preservation measures taken so that they can be reversed before the machines are put back into service. 42 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Preparations for use 4.19 Converter operation 4.19 Converter operation The following chapter is relevant only if the machine has been ordered for converter operation. Note The order number shows whether the machine was ordered for converter operation. In this case, digits 1, 2, 3 or 4 is located at the 6th position of the order number. 4.19.1 Supply line configuration NOTICE Asymmetric voltage load during operation on a TN system in delta connection An asymmetric voltage load of the machine winding can occur during operation on a TN system in delta connection with a grounded line conductor. Winding damage can result. Do not operate the machine on a TN system with a grounded line conductor. NOTICE Ground fault during operation on an IT system If a ground fault occurs when connected to an IT supply system, the insulation is excessively stressed. Winding damage can result. If possible, complete the process within two hours. Rectify the fault cause. Deploy a ground fault monitoring. 4.19.2 Converter input voltage The insulation system of SIMOTICS machines always complies with the requirements of stress category C (IVIC C = high stress). If voltage peaks higher than those specified according to IVIC C can occur, then please contact your Siemens partner: For a line supply voltage (converter input voltage) up to max. 480 V, and when controlled from a SINAMICS G/SINAMICS S converter with uncontrolled/controlled infeed: Comply with the guidelines for configuring motor and converter. For line voltages (converter input voltages) higher than 480 V, motors, which are ordered for converter operation, have an appropriate insulation system. Operation with a converter from another manufacturer: Comply with the permissible voltage peaks according to IEC 60034-18-41 in accordance with stress category C, dependent on the particular line voltage (converter input voltage) and the motor insulation system. SIMOTICS FD 1LM1 Operating Instructions 01/2019 43 Preparations for use 4.19 Converter operation NOTICE Material damage caused by an excessively high supply voltage The insulation system will be damaged if the supply voltage is too high for the insulation system. This can completely destroy the machine. Comply with the peak voltages as laid down in the guidelines above. 4.19.3 Reducing bearing currents Taking the following actions will reduce the bearing currents: Ensure that the contacts are established over a large area. Solid copper cables are not suitable for high frequency grounding because of the skin effect. Equipotential bonding conductors: Use equipotential bonding conductors: Between motor and driven machine Between motor and converter Between the terminal box and the RF grounding point at the motor enclosure. Selecting and connecting the cable: As far as possible, use symmetrically arranged, shielded connection cables. The cable shielding, made up of as many strands as possible, must have good electrical conductivity. Braided shields made of copper or aluminum are very suitable. The shield is connected at both ends, at the motor and converter. To ensure good discharging of high-frequency currents, provide contacting over a large surface area: - as contact established through 360 at the converter - at the motor, for instance with EMC glands at the cable entries 44 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Preparations for use 4.19 Converter operation If the cable shield is connected as described, then it ensures the specified equipotential bonding between the motor enclosure and converter. A separate RF equipotential bonding conductor is then not necessary. / / 3( / / / 3( / / 3( Concentric copper or aluminum shield / / 3( Steel armor If the cable shield is not connected due to special secondary conditions, or not adequately connected, then the specified equipotential bonding is not provided. In this particular case, use a separate RF equipotential bonding conductor: - Between the motor enclosure and protective ground rail of the converter. - Between motor enclosure and driven machine - Use braided flat copper straps or high-frequency cables with finely-stranded conductors for the separate RF equipotential bonding cable. - Ensure that the contacts are established over a large area. Overall system design To specifically reduce bearing currents, you must consider the system as a whole, which comprises the motor, converter, and driven machine. The following measures support you when reducing bearing currents and help to avoid damage: In the overall system, set up a properly meshed grounding system with low impedance. Use the common-mode filter (damping cores) at the converter output. The Siemens sales representative is responsible for selection and dimensioning. Limit the rise in voltage by using output filters. Output filters dampen the harmonic content in the output voltage. Note Converter documentation The operating instructions for the converter are not part of this documentation. Refer also to the configuration information for the converter. 4.19.4 Insulated bearings when operating the converter If the machine is operated from a low-voltage converter, insulated bearings are fitted at the NDE and an insulated encoder with insulated bearings (option). Comply with the plates on the machine relating to bearing insulation and possible bridges. SIMOTICS FD 1LM1 Operating Instructions 01/2019 45 Preparations for use 4.19 Converter operation Driving machine Motor Insulated bearings Insulated tachometer fitting Coupling Figure 4-2 Schematic representation of a single drive NOTICE Bearing damage The bearing insulation must not be bridged. Bearing currents can damage bearings. Do not bridge the bearing insulation for subsequent installation work, such as the installation of an automatic lubrication system or a non-insulated vibration sensor. Please contact the service center if necessary. Tandem operation If you connect two motors in series in "tandem operation", install an insulated coupling between the motors. Driving machine Motor Insulated bearings Insulated tachometer fitting Coupling Insulated coupling Figure 4-3 Schematic representation of a tandem drive NOTICE Bearing damage Bearing currents can flow if the coupling between the motors of the tandem drive is not insulated. This can damage the DE bearings of both motors. Use an insulated coupling to link the motors. 46 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Preparations for use 4.19 Converter operation See also Service and Support (Page 157) 4.19.5 Converter operation on a grounded network NOTICE Damage resulting from protective conductor currents When the machine is operated with a converter with current limiting, but without ground-fault monitoring, protective conductor currents of up to 1.7 times the phase conductor current can flow if there is a ground fault on the output side. Neither the PE conductors of normally rated multi-conductor connecting cables nor the PE connecting points of standard terminal boxes is suitable for this purpose. Material damage can result. Use an appropriately sized PE conductor. Connect the PE conductor to the grounding terminal on the motor enclosure. SIMOTICS FD 1LM1 Operating Instructions 01/2019 47 Preparations for use 4.19 Converter operation 48 SIMOTICS FD 1LM1 Operating Instructions 01/2019 5 Assembly 5.1 Safety instructions for mounting Observe the following when carrying out any work on the machine: Comply with the general safety instructions Comply with the applicable national and sector-specific regulations. When using the machine within the European Union, comply with the specifications laid down in EN 501101 regarding safe operation of electrical equipment. See also Safety information (Page 15) Injury and material damage caused by inappropriate fastening material If screws of an incorrect property class have been selected or if they have been fastened to an incorrect tightening torque, they may break or become loose. This will cause the machine to move, which could damage the bearings. The rotor could smash into the machine enclosure and machine parts could be flung out of place. This can result in death, serious injury or material damage. Comply with the required property classes for screwed connections. Tighten the screwed connections to the specified tightening torques. Injury and material damage caused by incorrect machine alignment If the machine has not been properly aligned, this will mean the fastening parts are subjected to stress/distortion. Screws may become loose or break, the machine will move, machine parts could be flung out of place. This can result in death, serious injury or material damage. Carefully align the machine to the driven machine. Material damage caused by improper handling Mounting parts such as temperature sensors or speed sensors are attached to the machine and could be ripped off or destroyed as a result of improper handling. This could lead to machine malfunctions, extending even to total loss of the machine. Where necessary, use suitable steps when performing installation work on the machine. Do not stand on cables or attachments during installation. Do not use attachments as steps. SIMOTICS FD 1LM1 Operating Instructions 01/2019 49 Assembly 5.2 Preparations for installation Damage to mounted parts and components as a result of high temperatures The motor components get very hot during operation. High temperatures can damage parts mounted by customers, such as cables manufactured out of materials that are not heat resistant. Temperature-sensitive parts must not come into contact with or be attached to components mounted on the machine. Only use heat-resistant mounting parts. The connecting cables and cable entries must be suitable for the particular application. Loss of conformity with European directives In the delivery state, the machine corresponds to the requirements of the European directives. Unauthorized changes or modifications to the machine lead to the loss of conformity with European Directives and the loss of the associated warranty. 5.2 Preparations for installation 5.2.1 Requirements for installation The following requirements must be satisfied prior to starting installation work: Staff have access to the operating and installation instructions. The machine is unpacked and ready for mounting at the installation location. Measure the insulation resistance of the winding before starting any installation work. If the insulation resistance lies below the specified value, take appropriate remedial measures. These remedial measures may necessitate the machine being removed again and transported. 5.2.2 Insulation resistance and polarization index Measuring the insulation resistance and polarization index (PI) provides information on the condition of the machine. It is therefore important to check the insulation resistance and the polarization index at the following times: Before starting up a machine for the first time After an extended period in storage or downtime Within the scope of maintenance work The following information is provided regarding the state of the winding insulation: Is the winding head insulation conductively contaminated? Has the winding insulation absorbed moisture? 50 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Assembly 5.2 Preparations for installation As such, you can determine whether the machine needs commissioning or any necessary measures such as cleaning and/or drying the winding: Can the machine be put into operation? Must the windings be cleaned or dried? Detailed information on testing and the limit values can be found here: "Testing the insulation resistance and polarization index" (Page 51) 5.2.3 Testing the insulation resistance and polarization index WARNING Hazardous voltage at the terminals During and immediately after measuring the insulation resistance or the polarization index (PI) of the stator winding, hazardous voltages may be present at some of the terminals. Contact with these can result in death, serious injury or material damage. If any power cables are connected, check to make sure line supply voltage cannot be delivered. Discharge the winding after measurement until the risk is eliminated, e.g. using the following measures: - Connect the terminals with the ground potential until the recharge voltage drops to a non-hazardous level - Attach the connection cable. Measure the insulation resistance 1. Before you begin measuring the insulation resistance, please read the operating manual for the insulation resistance meter you are going to use. 2. Short-circuit the ends of the temperature sensor cables before applying the test voltage. If the test voltage is connected to only one temperature sensor terminal, the temperature sensor will be destroyed. 3. Make sure that no power cables are connected. 4. Measure the winding temperature and the insulation resistance of the winding in relation to the machine enclosure. The winding temperature should not exceed 40 C during the measurement. Convert the measured insulation resistances in accordance with the formula to the reference temperature of 40 C. This thereby ensures that the minimum values specified can be compared. 5. Read out the insulation resistance one minute after applying the measuring voltage. SIMOTICS FD 1LM1 Operating Instructions 01/2019 51 Assembly 5.2 Preparations for installation Limit values for the stator winding insulation resistance The following table specifies the measuring voltage and limit values for the insulation resistance. These values correspond to IEEE 432000 recommendations. Table 5-1 Stator winding insulation resistance at 40 C UN V Umeas V M U 1000 500 5 1000 U 2500 500 (max. 1000) 100 2500 < U 5000 1000 (max. 2500) 5000 < U 12000 2500 (max. 5000) U > 12000 5000 (max. 10000) RC Urated = rated voltage, see the rating plate Umeas = DC measuring voltage RC = minimum insulation resistance at a reference temperature of 40 C Conversion to the reference temperature When measuring with winding temperatures other than 40 C, convert the measuring value to the reference temperature of 40 C according to the following equations from IEEE 43-2000. (1) RC = KT * RT (2) KT = (0.5) (40-T)/10 RC Insulation resistance converted to 40 C reference temperature KT Temperature coefficient according to equation (2) RT Measured insulation resistance for measuring/winding temperature T in C 40 Reference temperature in C 10 Halving/doubling of the insulation resistance with 10 K T Measuring/winding temperature in C In this case, doubling or halving the insulation resistance at a temperature change of 10 K is used as the basis. The insulation resistance halves every time the temperature rises by 10 K. The resistance doubles every time the temperature falls by 10 K. 52 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Assembly 5.2 Preparations for installation For a winding temperature of approx. 25 C, the minimum insulation resistances are 20 M (U 1000 V) or 300 M (U > 1000 V). The values apply for the complete winding to ground. Twice the minimum values apply to the measurement of individual assemblies. Dry, new windings have an insulation resistance of between 100 and 2000 M, or possibly even higher values. An insulation resistance value close to the minimum value could be due to moisture and/or dirt accumulation. The size of the winding, the rated voltage and other characteristics affect the insulation resistance and may need to be taken into account when determining measures. Over its operating lifetime, the motor winding insulation resistance can drop due to ambient and operational influences. Calculate the critical insulation resistance value depending on the rated voltage by multiplying the rated voltage (kV) by the specific critical resistance value. Convert the value for the current winding temperature at the time of measurement, see above table. Measuring the polarization index 1. To determine the polarization index, measure the insulation resistances after one minute and ten minutes. 2. Express the measured values as a ratio: PI = Rinsul 10 min / Rinsul 1 min Many measuring devices display these values automatically following the measurement. For insulation resistances > 5000 M, the measurement of the PI is no longer meaningful and consequently not included in the assessment. R(10 min) / R(1 min) Assessment 2 Insulation in good condition <2 Dependent on the complete diagnosis of the insulation NOTICE Damage to insulation If the critical insulation resistance is reached or undershot, this can damage the insulation and cause voltage flashovers. Contact the service center (Page 157). If the measured value is close to the critical value, you must subsequently check the insulation resistance at shorter intervals. Limit values of the anti-condensation heating insulation resistance The insulation resistance of the anti-condensation heating with respect to the machine housing should not be lower than 1 M when measured at 500 V DC. SIMOTICS FD 1LM1 Operating Instructions 01/2019 53 Assembly 5.3 Lift the machine to where it will be installed, and position it 5.2.4 Prepare the mating faces (IM B3) Ensure that the foundation faces are flat and free of contaminations.

Support the machine from below, e.g. using a wall bracket or by bolting it. 5.3 Lift the machine to where it will be installed, and position it 5.3.1 Preconditions for correct alignment and secure attachment Detailed specialist knowledge of the following measures is required in order to correctly align and securely fit the equipment. Preparing the foundation Selecting and mounting the coupling Measuring the concentricity and axial eccentricity tolerances Positioning the machine If you are not familiar with the prescribed measures and procedures, then you can make use of the services offered by the local Service Center (Page 157). 54 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Assembly 5.3 Lift the machine to where it will be installed, and position it 5.3.2 Checking the load handling attachments Inspect the load handling attachments such as the load trestles, lifting eyes and ring bolts and also the lifting gear, before lifting the machine: Inspect the load handling attachments on the machine for possible damage. Replace any load suspension equipment that is found to be damaged. Before use, check that the load suspension equipment is correctly attached. When lifting the machine, use only approved and undamaged lifting gear of sufficient rated capacity. Check the lifting gear prior to its use. WARNING The machine can be dropped If the load handling attachments and lifting gear are damaged or not correctly secured, the machine may be dropped during lifting. This can result in death, serious injury or material damage. Inspect the load handling attachments and lifting gear before use. 5.3.3 Removing the rotor shipping brace If a rotor shipping brace is attached to the machine, remove it at the last possible moment, for example, when you are ready to push on the output or drive element. 5.3.4 Removing the rotor shipping brace from machines in vertical type NOTICE Removing the rotor shipping brace in the horizontal position. Dismantling the rotor shipping brace when the machine is in a horizontal position could damage the bearings. Only remove the rotor shipping brace when the machine is in a vertical position. NOTICE Turning the motor over without rotor shipping brace Failure to fit the rotor shipping brace can result in damage to the bearings while the machine is being turned onto its side. Fix the rotor in place before you turn the machine into a horizontal position. SIMOTICS FD 1LM1 Operating Instructions 01/2019 55 Assembly 5.3 Lift the machine to where it will be installed, and position it Note Store the rotor locking device Be sure to store the rotor locking device. It must be remounted for possible disassembly and transport. 5.3.5 Removing anti-corrosion protection Machined, bare metallic surfaces of the motor, such as the shaft end, fitted key, foot and flange surfaces, are treated with an anti-corrosion agent. 1. Remove this layer of anti-corrosion agent from the mounting surfaces of the motor by wiping it away with an absorbent cloth or paper sheet. NOTICE Damage to the machine surface Using metal objects such as scrapers, spatulas, or plates to remove the anti-corrosion protection could result in damage to the surfaces of the machine parts. 2. Then lightly oil the bare surfaces again. 5.3.6 Mounting the output elements Type of balancing The rotor is dynamically balanced. For shaft extensions with featherkeys, the balancing type is specified using the following coding on the face of the drive end of the shaft: "H" means balancing with a half feather key "F" means balancing with a whole feather key Figure 5-1 56 Balancing type on the drive-end side SIMOTICS FD 1LM1 Operating Instructions 01/2019 Assembly 5.3 Lift the machine to where it will be installed, and position it Pushing on the power output elements Requirements: - The coupling and/or the output element must be appropriately dimensioned for the operating case at hand. Carefully comply with the coupling manufacturer's instructions. - Make sure that the balancing type of the transmission element correctly matches the type of balance of the rotor. - Use only ready drilled and balanced transmission elements. Check the hole diameters and the balancing status before pulling them on. Thoroughly clean the shaft extension. Pulling on: - Warm up the transmission elements to expand them before pulling them on. Select the temperature difference for the heating process to suit the coupling diameter, fit and material. Carefully comply with the coupling manufacturer's instructions. - Power output elements may only be pushed on or pulled off with the correct equipment. The transmission element must be pulled on in one continuous operation via the front thread holes in the shaft or pushed on by hand. - Do not strike it with a hammer, as this would damage the bearings. Shaft extensions with feather key To maintain the balancing quality, you have the following options: If the transmission element is shorter than the feather key with balancing type "H", then you must machine off the section of feather key protruding from the shaft contour and transmission element in order to maintain the balance quality. If the transmission element is drawn up on to the shoulder of the shaft, you must ensure that the part of the coupling groove where the feather key is not inserted is taken into consideration when balancing the coupling. The following applies to all four-pole machines with a frequency 60 Hz: The feather key must be shortened if the coupling hub us shorter than the feather key. The center of gravity of the coupling half should be within the length of the shaft end. The coupling used must be prepared for system balancing. The number of poles of the machine is specified on the rating plate, at the 10th position of the motor type. There, four-pole machines are marked with a "B". Danger when feather keys are flung out The feather key is only secured to prevent it falling out during transport. The feather key may be flung out if the motor is operated without fitted transmission elements, such as coupling, etc. This can result in death, serious injury or material damage. Only operate the motor with the transmission element pulled on. For test operation or when commissioning without transmission element, carefully secure the feather key using a suitable locking element. When doing this, take into account the type of machine balancing. SIMOTICS FD 1LM1 Operating Instructions 01/2019 57 Assembly 5.3 Lift the machine to where it will be installed, and position it 5.3.7 Lifting and transportation To safely lift and transport the machine, the following requirements must be met: Personnel operating cranes and fork-lift trucks must be appropriately qualified. If the machine is packed, depending on the weight, size and on-site conditions, lift crates and transport frames using a fork-lift truck or a crane with slings. Use a crane or fork-lift truck suitable for the load. When lifting the machine, use only approved and undamaged sling guides and spreaders of sufficient rated capacity. Check the lifting equipment prior to its use. The weight of the machine is shown on the rating plate. When lifting the machine, refer to the information on the lifting plate. - Comply with the specified spreading angles. - Do not exceed the maximum lifting acceleration and lifting speed specified on the lifting plate. Lift the machine without jerking it. Acceleration a 0.4 g ( 4 m/s2 ) Velocity v 20 m/min WARNING Transport for a different type of construction If you do not transport or lift the machine in a position appropriate for its construction, the machine can tip, slip into the lifting equipment or fall down. This can result in death, serious injury or material damage. Use only the load carrying device on the stator frame for lifting. Use the load carrying device appropriate for the machine position. Only use suitable rope guiding or spreading devices. WARNING Center of gravity not centered If the center of gravity of a load is not located centrally between the attachment points, the machine can tip over or slip out of the lifting equipment and fall when it is being transported or lifted. This can result in death, serious injury or material damage. Comply with the handling instructions on the machine when transporting it. Be aware of the possibility of different loads on the sling ropes or lifting straps and the carrying capacity of the lifting equipment. Always take account of the center of gravity when transporting or lifting the machine. If the center of gravity is not located centrally between the attachment points, then position the hoisting hook above the center of gravity. 58 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Assembly 5.3 Lift the machine to where it will be installed, and position it Note Place the machine in a secure and raised position In order to obtain easy and safe access to the underside of the machine, place it in a secure and raised position. DANGER Standing under suspended loads If the lifting gear or load handling attachments were to fail, the machine could fall. This can result in death, serious injury or material damage. Never remain under or in the immediate vicinity of the machine when it is raised. 5.3.8 Putting the machine down Requirements The following preconditions must be satisfied before setting down the machine at the installation location: The mating faces must be clean. The anti-corrosion protection paint has been removed from the mating faces, such as the machine mounting feet, flange, ... There is no condensation present within the machine. Setting down the machine Set down the machine slowly and carefully at the installation location to avoid any impact. See also Draining condensation (Page 60) SIMOTICS FD 1LM1 Operating Instructions 01/2019 59 Assembly 5.3 Lift the machine to where it will be installed, and position it 5.3.9 Draining condensation Under the following conditions it is possible that condensate may accumulate within the machine: Wide fluctuations in the ambient temperature, such as direct sunshine combined with high atmospheric humidity Intermittent operation or load fluctuations during operation NOTICE Damage due to condensate If the stator winding is damp, its insulation resistance will be reduced. This can result in voltage flashovers, which can destroy the winding. Condensate can also cause rust to form within the machine. Ensure that condensate can drain away. Depending on the type of installation, the water drainage holes are located at the bottom: Allow the condensation water to discharge for vertical placement In the DE bearing shield, water drain holes are located in the area of the mounting feet or opposite the regreasing system. They are sealed with screw plugs. Figure 5-2 60 Condensation water drain for vertical mounting SIMOTICS FD 1LM1 Operating Instructions 01/2019 Assembly 5.3 Lift the machine to where it will be installed, and position it Allow the condensation water to discharge for horizontal placement The water drain holes are located in the lower side of the stator enclosure, and sealed with screw plugs. Figure 5-3 Condensation water drain for horizontal mounting To drain the condensation water, proceed as follows: 1. Remove the screw plugs to allow the condensation water to drain. 2. Then reinsert the screw plugs. NOTICE The degree of protection is reduced Nominally the degree of protection of the machine is reduced to IP44 when the screw plug is removed. 5.3.10 Roughly aligning the machine Requirement The transmission element such as a coupling half has already been pulled on. Roughly aligning the machine For horizontal positioning, push the motor sideways across the foundation. When doing so, ensure that the axial position is maintained. SIMOTICS FD 1LM1 Operating Instructions 01/2019 61 Assembly 5.4 Installing the machine 5.4 Installing the machine 5.4.1 Preconditions for smooth, vibration-free operation Preconditions for smooth, vibration-free operation: Stable foundation design Precise alignment of the machine Correct balancing of parts to be fitted to the shaft end. Maintaining the vibration velocity according to ISO 108163 5.4.2 Aligning the machine to the driven machine and mounting (IM B3 / IM B35) 1. Refer to any instructions for aligning the driven machine and those of the coupling manufacturer. 2. Align the machines with coupling output to the driven machine in such a manner that the center lines of the shafts at the operating temperature do not have any parallel or angular offset. This ensures that no additional forces affect their bearings during operation. If the thermal change of the motor and the driven machine is different, couple in the cold state with an appropriate alignment offset. The alignment offset to be set in the cold state must be determined and specified by the system specialist. 3. For the vertical positioning (x0), place thin shims over a large surface area under the machine feet. The number of shims should be kept as low as possible, i.e. stack as few as possible. This also prevents the machine being subjected to any stress/distortion. Use the existing tapped holes for the forcing-off bolts to raise the machine. The balance state of the shaft (full-key or half-key balancing) and alignment errors primarily influence the service life of the bearing, especially for high motor speeds or when using rigid couplings. 62 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Assembly 5.4 Installing the machine 4. When positioning the machine, ensure that a uniform axial gap (y0) is maintained around the coupling. 5. Fix the machine to the foundation.

The choice of fit for the mating flange on the driven machine is the system manufacturer's or the plant operator's responsibility. Note If the machine is not fitted with a standard flange, align the machine to suit the driven machine. Procedure The machine axis must be horizontal when it is lifted and the flange must be parallel to the mating flange, so as to avoid seizing and stressing. Otherwise damage to the centering will result. 1. Grease the centering flange with assembly paste to make the process easier. 2. Screw three studs into tapped holes spaced about 120 apart around the driven machine flange. The studs act as positioning aids. 3. Position the machine so that its axis is aligned with that of the driven machine, but not yet quite touching. Advance the machine slowly towards the driven machine; advancing too quickly risks damaging the centering. 4. If necessary, rotate the machine into the right position so that the clearance holes in the flange are central to the tapped holes. 5. Move the machine fully up against the mating flange so that it is fully in contact. 6. Fix the machine using the flange fixing bolts, finishing by replacing the studs. See also Tightening torques for screw and bolt connections (Page 159) There is a threaded hole M36 at the bottom of the machine where you can fasten the support base. Mount the support base so that no additional mechanical tensions can occur in the housing. WARNING Mechanical tensions The machine may be damaged by additional mechanical tensions in the housing caused by incorrect mounting of the support base. The machine or machine parts may loosen during operation. This can result in death, serious injury or material damage. Mount the support base so that no additional mechanical tensions can occur in the housing. 64 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Assembly 5.4 Installing the machine 5.4.4 Aligning the machine to the driven machine and attaching it to it (IM V1, IM V10) The standard flange is provided with a centering.

The grounding conductor can be connected as follows: With stranded cables with cable lugs With flat cables with cable end designed accordingly As an alternative, you can connect the grounding conductor without cable lugs using a clamping plate at the marked connection point. Connecting the grounding conductor Use the connecting terminals designated for the grounding conductor in the terminal box. Ensure that the connecting surface is bare and is protected against corrosion using a suitable substance, e.g. acid-free Vaseline. Arrange the flat washer and spring washer under the screw head. SIMOTICS FD 1LM1 Operating Instructions 01/2019 77 Electrical connection 6.4 Preparation Check that the maximum permissible clamping thickness of 10 mm for the cable lug or strap is not exceeded. Fasten the clamping screw according to the following table. Screw-in depth and tightening torque are different depending on whether cable lugs or ground terminals are used. Screw Screw-in depth Tightening torque M6 > 6 mm 8 Nm When using cable lugs When using grounding terminals M8 > 8 mm 20 Nm M12 x 25 > 16 mm 38 Nm M16 x 35 > 20 mm 92 Nm M6 > 9 mm 8 Nm M8 > 12 mm 20 Nm M10 > 15 mm 40 Nm M12 > 18 mm 70 Nm M16 > 20 mm 170 Nm See also Converter operation (Page 92) 6.4.4 Connection without terminal box If the machine was ordered without terminal box (where the cables are simply brought out of the motor), then the proper connection must be made in an external terminal box. WARNING Incorrect dimensioning Faults can occur if the appropriate technical data is not complied with when connecting up. For instance, degree of protection, minimum air and creepage distances. These faults can result in eventual or immediate death, serious injury or material damage. Ensure that the external terminal box is dimensioned according to the data on the rating plate and is suitable for the respective use. 78 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Electrical connection 6.4 Preparation 6.4.5 Connecting the machine for a specific direction of rotation If the machine has one shaft extension or two shaft extensions with different diameters, the direction of rotation when looking at the front of the single or the thicker shaft extension is defined as follows: If you connect the line cables with phase sequence L1, L2, L3 to U, V, W or according to NEMA at T1 T2 T3, then a clockwise phase sequence is obtained. If you interchange two connections, e.g. L1, L2, L3 at V, U, W or according to NEMA at T2 T1 T3, then a counterclockwise phase sequence is obtained. On machines which are only allowed to run in one direction, the rating plate shows an arrow which indicates the permitted direction of rotation, and it also specifies the terminal connections in the required phase sequence. Check the appropriate data before connecting the line feeder cables. NOTICE Incorrect direction of rotation The machine will not be adequately cooled if it is operated other than how it was originally ordered or with the incorrect direction of rotation. This can result in machine damage. Observe the direction of rotation data on the nameplate. 6.4.6 Undrilled entry plate If the entry plate is undrilled, you should match the number and size of the cable glands to the operating conditions. 1. Unscrew the cable entry plate. 2. Drill the required number of holes or threads in the required size into the cable entry plate. The thickness of the plate is selected in such a way as to give a sufficient number of turns when the holes are tapped. Please note that you are responsible for ensuring that the entry plate still has sufficient strength after the holes have been drilled and tapped. 3. Mount the cable entry plate and the cables with the cable glands onto the terminal box.

Remove the top part of the strain relief and release the fixing screws for the bottom part of the strain relief . The strain relief device can be located either in the terminal box or externally. If necessary, switch the direction sense of the strain relief device. 2. Cut the seal insert so that its opening is 1 to 3 mm smaller than the diameter of the cable. 3. Pull the sealing insert over the end of the cable. 4. Prepare the end of the cable depending on the cable and its use, e.g. with a cable lug. 80 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Electrical connection 6.5 Inserting and routing the cables 5. Connect the ends of the cables to the terminals in accordance with the circuit diagram. The circuit diagram is located in the cover of the terminal box. Refer to the "Connecting cables..." section for more information. 6. You might need to use a sleeve made of suitable sealing tape to modify the diameter where it passes through the sealing insert. Push the sealing insert onto the prepared sleeve. 7. Insert the cable with the seal insert in position into the gland opening. Screw the strain relief device together once the cable is in a concentric position in the gland opening. 8. Secure the strain relief device. 9. Tighten the clamping screws of the strain relief device so that the cable is clamped as necessary, but do not damage the cable insulation. We recommend a torque of 5 Nm. 10.Retighten the clamping screws after 24 hours. WARNING Damage to insulation If you tighten the strain relief clip clamping screws too tightly this can damage the insulation. Damaged insulation can result in arcing. This can result in death, serious injury or material damage. Tighten the strain relief clip clamping screws to the specified torque. 6.5.2 Bringing cables into the terminal box 1XB... with cable gland The connection cables are inserted into the terminal box via an exchangeable cable entry plate or cable entry support.

Ensure that the cable entry plate can be assembled after drilling and that it features sufficient stiffness. 3. Fit the required cable glands. 4. Route the cables through the cable glands. 5. Fit the cable entry plate to the terminal box with the assembled cables. 6. Connect the ends of the cables to the terminals in accordance with the circuit diagram. The circuit diagram is located in the cover of the terminal box. Refer to Chapter "Connecting cables ..." for more information. 6.5.3 Laying cables Lay the cables in accordance with IEC/EN 60364-5-52. Use EMC cable glands for fixed cables. Screw the EMC cable glands into the threaded holes in the entry plate, which can be unscrewed. Use shielded cables whose shields are conductively connected to a large area of the terminal box of the motor via EMC cable glands. In the case of aluminum connecting bars, insert a steel washer between the cable lug and the connecting bar. This prevents contact corrosion. Arrange the exposed connecting cables in the terminal box so that the PE conductor has excess length and the insulation of the cable strands cannot be damaged. Close and seal unused bushings and glands using a metal screw plug. This is the way to achieve a high frequency-proof shielding. 6.5.4 Connecting cables with cable lugs 1. Select the cable lugs according to the required cable cross-section and fixing screw or stud size. Information about the maximum cross-section for the respective standard terminal box design can be found in the catalog. A sloped/angular arrangement of the supply cables is only permitted provided the required minimum air clearances are met. 2. Remove the insulation from the conductor ends so that the remaining insulation reaches almost up to the cable lug . Connect only one conductor per cable lug. 82 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Electrical connection 6.5 Inserting and routing the cables 3. Fasten the cable lug to the end of the conductor correctly, e.g. by squeezing. Figure 6-9 Connection with cable lug and fixing screw (schematic diagram) 4. Insulate the cable lug sleeves where necessary to ensure minimum air clearances and the creepage distance are maintained. 5. Place the cable lug on the terminal support. If you are using a disconnecting link, check its positioning. For terminal boxes 1XB7740 and 1XB7750, place the cable lug on the busbar. 6. Tighten the fixing element with the corresponding tightening torque: Fixing element Tightening torque Fastening screw M12 20 Nm Fixing screws M16 40 Nm Fixing nuts M12 20 Nm Note You can find more information in Chapter 2 of catalog D81.8. 6.5.5 Connecting cables without cable lugs Lug terminal connections - which are suitable for connecting flexible and stranded conductors without the use of wire end ferrules - may be installed if ordered accordingly. If you wish to use conductor end sleeves, then correctly crimp these onto the end of the conductor before connecting up. NOTICE Overheating of the conductor ends If the end of the conductor is not correctly enclosed by the wire end ferrule, but is trapped by it, this can lead to overheating. Insert only one conductor end into each wire end ferrule, and attach the wire end ferrule correctly. Insert only one conductor end into each terminal. SIMOTICS FD 1LM1 Operating Instructions 01/2019 83 Electrical connection 6.5 Inserting and routing the cables Procedure When connecting, carefully maintain the minimum clearances and creepage distances. 1. Open the terminal box and cut the cable to the correct length. The clips of the 1XB7730/1XB7731 terminal boxes can accept cables with maximum 185 mm cross-section. 2. Prepare the end of the cable depending on the cable and its use. It is not permissible that the cable connection is subject to external forces. 3. Insulate the conductor ends in such a way that the remaining insulation reaches almost up to the cable lug. 4. Make sure the terminal clamps , are arranged correctly for the size of the conductor. Insert the cable into the terminal clamps. Tighten the clamping nuts to the tightening torque as specified in the following table. Terminal box Tightening torque GT640 / 1XB1621 / 1XB1631 / 1XB1634 8 Nm 1XB7730 / 1XB7731 4 Nm 1XB7740 / 1XB7750 8 Nm Figure 6-10 Connection using terminal clamps (schematic diagram) 5.

Immediately before inserting the aluminum conductor, remove the oxide layer from the contact areas on the conductor and/or the mating piece. Do this using a brush or file. Then grease the contact areas immediately using neutral Vaseline. This prevents a new oxide layer from forming. NOTICE Aluminum flow due to contact pressure Aluminum flows following installation due to the contact pressure. The connection using clamping nuts can loosen as a result. The contact resistance increases, obstructing the current from being conducted. This can result in fire and material damage to the machine - or even in total failure, as well as material damage to the plant or system due to machine failure. Retighten the clamping nuts after approximately 24 hours and then again after approximately four weeks. Make sure that the terminals are de-energized before you tighten the nuts. For 1XB7.. terminal boxes with aluminum connection bars, you can also connect copper cables using copper cable lugs. 6.5.7 Using single-stranded cables NOTICE High temperatures from induced eddy currents With high currents and where several single-stranded cables are used instead of multiplestranded cables, high temperatures can result in the cable entry area due to induced eddy currents. This can result in material damage or even a machine failure. After commissioning, ensure that the temperature limits of the connected power cables are not exceeded during operation. This temperature effect can be reduced by altering the conditions at the entry points or by using modified cable entry plates after consultation with the manufacturing plant. Use a cable entry plate made of non-ferrous metal. 6.5.8 Internal equipotential bonding Between the ground terminal in the terminal box enclosure and the machine enclosure, the fixing screws of the terminal box serve as PE conductor connection. SIMOTICS FD 1LM1 Operating Instructions 01/2019 85 Electrical connection 6.5 Inserting and routing the cables Between terminal box cover and terminal box enclosure, the cover fixing screws serve as equipotential bonding. A special external ground conductor is only installed if, for example, flat seals are mounted without additional support. When performing any installation work, you must always take care to ensure that all equipotential bonding measures remain effective. 6.5.9 Stepless mating face for the seal in the terminal box cover The sealing face of the terminal box cover is formed by the terminal box enclosure and the cable entry element. Therefore make sure these parts are correctly aligned, so as to ensure the seal and hence the degree of protection. Align the cable entry support and the cable entry plate to the terminal box enclosure so that the sealing surface between the terminal box and the terminal box cover form a flat face. There must be no steps in the sealing area. 6.5.10 Minimum air clearances After proper installation, verify that the minimum air clearances between non-insulated parts are maintained. Be aware of any protruding wire ends. Table 6-4 Minimum air clearance dependent on rms value of the alternating voltage Urms Rms value of the alternating voltage Vrms Minimum air clearance 500 V 8 mm 630 V 10 mm 800 V 12 mm 1000 V 14 mm 1250 V 18 mm Values apply at an installation altitude of up to 2000 m. When determining the required minimum air clearance, the voltage value in the table may be increased by a factor of 1.1, so that the rated input voltage range is taken into account during general use. 86 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Electrical connection 6.6 Connecting the auxiliary circuits 6.5.11 Finishing connection work 1. Before closing the terminal box, please check that: - The electrical connections in the terminal box have been made in accordance with the specifications above and tightened with the correct tightening torque. Remove the used bolts and fastening elements. - The machine is connected in such a way that it rotates in the direction specified. - The inside of the terminal box is clean and free of any cable debris, dirt and foreign bodies. - All of the seals and sealing surfaces of the terminal box are intact and in a good condition. - Unused cable entries are closed and their plugs are tightly screwed in place, i.e. they can only be released using a tool. - The connecting cables are freely routed. The cable insulation cannot be damaged in operation. 2. Close the terminal box using the cover fixing screws, see Chapter Tightening torques for screw connections. See also Tightening torques for screw and bolt connections (Page 159) Mounting/removing the terminal box (Page 75) 6.6 Connecting the auxiliary circuits 6.6.1 Selecting cables Take the following criteria into account when selecting the connecting cables for the auxiliary circuits: Rated current Rated voltage System-dependent conditions, such as ambient temperature, routing type, cable crosssection as defined by required length of cable, etc. Requirements according to IEC/EN 602041 SIMOTICS FD 1LM1 Operating Instructions 01/2019 87 Electrical connection 6.6 Connecting the auxiliary circuits 6.6.2 Bringing cables into the auxiliary terminal box and routing them The required data for connecting the auxiliary circuits is located on the terminal diagram on the inside of the respective auxiliary terminal or terminal box cover. In some cases a terminal strip is installed in the main terminal box for the auxiliary circuit connections. The required stripped length on conductors for auxiliary terminals differs according to terminal type (6 to 9 mm). When the length is correct, the conductor should reach the stop in the terminal and at the same time the conductor insulation should reach the contact part of the terminal. Adapting the cable glands A plate is bolted to the terminal box enclosure via a rectangular cutout through which the connecting cables enter. The plate is generally delivered with threaded holes and cable glands. 1. Open the auxiliary terminal box and undo the cable entry plate screws. Depending on the terminal box version, the cable entry plate is below a steel screening plate. 2. For the undrilled version, drill the required number of holes or threads in the required size of the cable gland into the cable entry plate. 3. Mark the cables if necessary for subsequent assignment. 4. Pull the cables through the cable glands and the cable entry plate, and connect the cables. 5. Fit the cable entry plate. 6. Make sure that the seal on the screwed sockets for the cable glands satisfies the degree of protection. 6.6.3 Connecting temperature monitoring for the stator winding The stator winding is monitored for thermal loading by temperature sensors embedded in the stator winding. 88 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Electrical connection 6.6 Connecting the auxiliary circuits The connecting cables of the temperature sensors are routed to the main or auxiliary terminal box, depending on the version. The connection and assignment of the terminals is specified in the circuit diagram. WARNING Hazard due to electric shock The installation of the temperature sensors for the winding monitoring with respect to the winding is implemented according to the requirements for basic insulation. The temperature sensor connections are located in terminal boxes, safe to touch, and have no protective separation. This is the reason that in the case of a fault, a hazardous voltage can be present at the measuring sensor cable. When touched, this can result in death, severe bodily injury and material damage. When connecting the temperature sensor to external temperature monitoring devices, when required, apply additional measures to fully comply with the requirements set out in IEC 60664-1 or IEC 61800-5-1 "Hazard due to electric shock". 6.6.4 Terminating the connection work (auxiliary circuit) 1. Before closing the auxiliary terminal box, please check that: - The cables are connected in accordance with the terminal diagram. - The cables are freely arranged so that they cannot come into contact with the machine, and the cable insulation cannot be damaged. - The inside of the terminal box is clean and free of any cable debris, dirt and foreign bodies. - The cable glands are firmly tightened, are suitable with respect to the degree of protection, type of cable routing, permissible cable diameter, etc., and have been mounted in full compliance with specifications and regulations - The threads in the connection plate are sealed using cable and conductor entries, thread adapters or sealing plugs that achieve the respective degree of protection. - Unused cable entries are sealed. The sealing elements are firmly screwed in, and can only be released using a tool. - All of the seals/gaskets and sealing surfaces of the terminal box are in good condition - The screws of all of the screw clamps are fully tightened, even if they are not being used. 2. Close the auxiliary terminal box using the cover supplied for this purpose. See section "Tightening torques for screw and bolt connections (Page 159)" for the tightening torque of the fixing bolts for the cover. SIMOTICS FD 1LM1 Operating Instructions 01/2019 89 Electrical connection 6.6 Connecting the auxiliary circuits 90 SIMOTICS FD 1LM1 Operating Instructions 01/2019 7 Start-up Observe the following when carrying out any work on the machine: Comply with the general safety instructions Comply with the applicable national and sector-specific regulations at the place of installation When using the machine within the European Union, comply with the specifications laid down in EN 501101 regarding safe operation of electrical equipment. See also Safety information (Page 15) 7.1 Checks to be carried out prior to commissioning Once the system has been correctly installed, you should check the following prior to commissioning: Note Checks to be carried out prior to commissioning The following list of checks to be performed prior to commissioning does not claim to be complete. It may be necessary to perform further checks and tests in accordance with the specific situation on-site. The machine is undamaged. The machine has been correctly installed and aligned, the transmission elements are correctly balanced and adjusted. All fixing screws, connection elements, and electrical connections have been tightened to the specified tightening torques. The operating conditions match the data provided in accordance with the technical documentation, such as degree of protection, ambient temperature, etc.. Moving parts such as the coupling move freely. All touch protection measures for moving and live parts have been taken. For test operation or when commissioning without output element, carefully secure the feather key using a suitable security element. When doing this, take into account the balancing type of the motor. SIMOTICS FD 1LM1 Operating Instructions 01/2019 91 Start-up 7.2 Converter operation Second shaft extension If the second shaft extension is not used: Carefully secure the feather key to prevent it from being thrown out, and for balancing type "H" (standard type), ensure its weight is reduced to approximately 60 % of the original value. Using covers, carefully secure the unused shaft extension so that it cannot be touched. The bearing insulation should be implemented as shown on the plates. Electrical connection The grounding and equipotential bonding connections have been made correctly. The machine is connected so that it rotates in the direction specified. Appropriately configured control and speed monitoring functions ensure that the motor cannot exceed the permissible speeds specified in the technical data. For this purpose, compare the data on the rating plate or, if necessary, the system-specific documentation. The minimum insulation resistance values are within tolerance. Minimum air clearances have been maintained. Any supplementary motor monitoring devices and equipment have been correctly connected and are functioning correctly. All brakes and backstops are operating correctly. At the monitoring devices, the values for "Warning" and "Shutdown" are set. 7.2 Converter operation The following chapter is relevant only if the machine has been ordered for converter operation. Note The order number shows whether the machine was ordered for converter operation. In this case, digits 1, 2, 3 or 4 is located at the 6th position of the order number. Converter operation If the design of the motor requires connection to a particular converter type, the rating plate will contain corresponding additional information. The converter is correctly parameterized. The parameterization data is specified on the rating plate of the machine. Information about the parameters is available in the operating instructions for the converter. 92 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Start-up 7.3 Measuring the insulation resistance before commissioning Any supplementary motor monitoring devices and equipment have been correctly connected and are functioning correctly. In continuous operation, the motor cannot exceed the specified upper speed limit nmax or undershoot the lower speed limit nmin. The permissible acceleration time to the limit speed nmin depends on the parameter assignment. 7.2.1 Operation on a converter with a low pulse frequency NOTICE Increased motor temperature If the pulse frequency is less than the rated pulse frequency, then increased motor losses occur. This results in a higher motor temperature. Reduce the power to prevent exceeding the temperature class and to avoid consequential premature thermal aging of the insulation. Contact the Service Center if necessary. WARNING Dangerous voltage via the converter As long as the feeding converter is switched on, or the DC link of the converter is not discharged, there can be a voltage at the motor terminals even when the rotor is not moving. The voltage is up to 1000 V, depending on the converter type. Ensure that the five safety rules (Page 15) are followed before working on the motor. 7.3 Measuring the insulation resistance before commissioning Measuring the insulation resistance and polarization index (PI) provides information on the condition of the machine. It is therefore important to check the insulation resistance and the polarization index at the following times: Before starting up a machine for the first time After an extended period in storage or downtime Within the scope of maintenance work The following information is provided regarding the state of the winding insulation: Is the winding head insulation conductively contaminated? Has the winding insulation absorbed moisture? SIMOTICS FD 1LM1 Operating Instructions 01/2019 93 Start-up 7.4 Greasing the roller bearings prior to commissioning As such, you can determine whether the machine needs commissioning or any necessary measures such as cleaning and/or drying the winding: Can the machine be put into operation? Must the windings be cleaned or dried? Detailed information on testing and the limit values can be found here: "Testing the insulation resistance and polarization index" (Page 51) 7.4 Greasing the roller bearings prior to commissioning The following information assumes that the specified storage conditions have been complied with. General specifications Pay attention to the instructions on the lubricant plate. Regrease in portions. The shaft must rotate so that the new grease can be distributed in the bearings. Regreasing the roller bearings prior to commissioning If the period between delivery and commissioning is more than a year and less than four years: - Re-grease the roller bearings with twice the amount of grease specified on the lubricant plate. - Check the bearing temperature, as far as possible. Regreasing roller bearings before commissioning You must regrease the roller bearings under the following conditions: If the machine has been in storage for more than four years. If the machine has not been stored in accordance with the specifications in the "Storage" section. Procedure 1. Remove the bearing, regreasing pipes, grease nipples and the bearing cap. 2. Flush out the old grease. 3. Check the bearings before regreasing. If necessary, install new bearings. 4. Lubricate the bearings and reinstall the bearing components. 94 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Start-up 7.5 Setting the automatic regreasing system See also Regreasing intervals and types of grease for operating roller bearings (Page 117) Stoppages (Page 107) Transport (Page 34) 7.5 Setting the automatic regreasing system The relubrication is performed depending on the external voltage present at the regreasing system. Prior to commissioning, set the time interval and the relubrication quantity at the automatic regreasing system. Observe the operating instructions for the regreasing system for its operation and the replacement of the grease cartridges. See also Interlock circuit for the automatic regreasing system (option) (Page 31) 7.6 Setpoint values for monitoring the bearing temperature Prior to commissioning If the machine is equipped with bearing thermometers, set the temperature value for disconnection on the monitoring equipment before the first machine run.

Start up the machine without a load. To do this, close the circuit breaker and do not switch off prematurely. Check whether it is running smoothly. Switching the machine off again while it is starting up and still running at slow speed should be kept to a bare minimum, for example for checking the direction of rotation or for checking in general. Allow the machine to run down before switching it on again. 2. If the machine is running smoothly and evenly, switch on the cooling equipment. Continue to observe the machine for a while in no-load operation. 96 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Start-up 7.8 Test run 3. If it runs perfectly, connect a load. NOTICE Thermal overload of motors connected directly to the line supply In addition to the load torque, the ramp-up (accelerating) time is essentially influenced by the moment of inertia to be accelerated. While ramping up when connected to the line supply, the inrush (starting) current is a multiple of the rated current. This can result in thermal overload. This can damage the motor. As a consequence, when ramping up, observe the following: Monitor the ramp-up time and number of consecutive starts. Comply with the limit values and/or ramp-up conditions specified in the catalog or the order documentation. 4. During the test run, check and document the following: - Check whether it is running smoothly. - Document the voltage, current and power values. As far as possible, document the corresponding values of the driven machine. - If this is possible using the available measuring equipment, check the bearing and stator winding temperatures until they have reached steady-state values. - Check the machine for noise or vibrations on the bearings or bearing shields as it runs. 5. In case of uneven running or abnormal noise, switch off the machine. As the machine runs down, identify the cause. - If the mechanical operation improves immediately after the machine is switched off, then the cause is magnetic or electrical. - If the mechanical running does not improve immediately after switching the machine off, then the cause is mechanical. - Imbalance of the electrical machine or the driven machine - The machine set has not been adequately aligned - The machine is being operated at the system resonance point. System = motor, base frame, foundation, ... NOTICE Serious damage to the machine If the vibration values in operation are not maintained in accordance with DIN ISO 10816-3, then the machine can be mechanically destroyed. During operation, observe the vibration values in accordance with DIN ISO 108163. Note You can find more information in Chapter 2 of catalog D81.8. SIMOTICS FD 1LM1 Operating Instructions 01/2019 97 Start-up 7.9 Switching off 7.9 Switching off If the controller does not do this automatically, switch on any anti-condensation heating during stoppages. This will avoid the formation of condensation. Do not switch on the anti-condensation heating for at least two hours after the motor has been switched off. This prevents damage to the winding insulation. 7.10 Setting the motor parameters at the converter The selection of the motor type is used to pre-assign specific motor parameters and to optimize the operating characteristics and behavior. If the incorrect motor type has been selected, then this can result in undesirable operating states, for instance increased noise. If you use the SINAMICS G120/G150 or SINAMICS S120/S150 converter, you can set the motor parameters using STARTER or the "Advanced Operating Panel" AOP30. If you use the SINAMICS G120P converter, you can set the motor parameters using the "Intelligent Operator Panel" (IOP). Note Preset space-vector modulation for SINAMICS S converters Unlike SINAMICS G converters, space-vector modulation is preset for SINAMICS S converters. Provided permitted by the application, the space-vector modulation can be changed manually to an optimized pulse pattern for SIMOTICS FD motors. The SINAMICS parameter is p1802 = 19 in the STARTER and in the AOP30. 7.10.1 Selecting the motor type and motor data in the STARTER program Prerequisites The motor is connected to the converter and is ready for operation. The converter must have at least software version 4.6. You have installed the STARTER software with at least version 4.3.1 with SSP, and you are connected to the converter.

When using the machine within the European Union, comply with the specifications laid down in EN 501101 regarding safe operation of electrical equipment. See also Safety information (Page 15) Risk of injury due to rotating parts Rotating parts are dangerous. Touch protection against rotating parts is no longer guaranteed if covers are removed. Touching rotating parts can result in death, serious injury or material damage. Carefully ensure that all of the covers are closed while operational. First switch off and disconnect the machine if you must remove covers. Comply with the "Five safety rules": Only remove the covers when the rotating parts have come to a complete standstill. Danger as a result of stationary parts under voltage (live parts) Live parts represent a hazard. Touch protection against active (live) parts is no longer guaranteed if covers are removed. The minimum air and creepage distances may be fallen below (violated) when coming close to active parts. Touching or coming close can result in death, serious injury or material damage. Carefully ensure that all of the covers are closed while operational. First switch off and disconnect the machine if you must remove covers. Comply with the "Five safety rules": When the machine is in operation, the terminal boxes must remain closed at all times. Terminal boxes may be opened only when the machine is stopped and in a no-voltage condition. SIMOTICS FD 1LM1 Operating Instructions 01/2019 105 Operation 8.1 Safety instructions for operation Faults in operation Any changes with respect to the normal condition can indicate that the machine is not functioning correctly. Higher power consumption, temperatures or vibration levels. Unusual noise or smells. Monitoring devices respond. These changes can cause faults which can result in eventual or immediate death, serious injury or material damage. Immediately inform the service personnel. If you are in doubt, immediately switch off the machine, carefully observing the systemspecific safety conditions. Damage caused by condensation Humidity in the air can condense for intermittent duty or load fluctuations. Condensate can collect. Moisture can have a negative impact on the winding insulation or result in damage, such as corrosion. Ensure that any condensation can freely flow away. Risk of burn injuries as a result of hot surfaces Individual machine parts can become hot in operation. Burns can result when coming into contact with these parts. Never touch machine parts during operation. Allow the machine to cool down before starting work. Check the temperature of parts before touching them. If required, wear suitable protective equipment. Excessively high machine temperature when heating is switched on If the anti-condensation heating is operated while the machine is running, this can increase the temperatures inside the machine. Material damage can result. Make sure that the anti-condensation heating is switched off before the machine is switched on. Only operate anti-condensation heating when the machine is switched off. 106 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Operation 8.2 Switching on the machine 8.2 Switching on the machine 1. If at all possible, run the machine without load and check that it is running smoothly. 2. If it runs perfectly, connect a load. NOTICE Thermal overload of motors connected directly to the line supply In addition to the load torque, the ramp-up (accelerating) time is essentially influenced by the moment of inertia to be accelerated. While ramping up when connected to the line supply, the inrush (starting) current is a multiple of the rated current. This can result in thermal overload. This can damage the motor. As a consequence, when ramping up, observe the following: Monitor the ramp-up time and number of consecutive starts. Comply with the limit values and/or ramp-up conditions specified in the catalog or the order documentation. 3. If this is possible using the available measuring equipment, check the bearing and stator winding temperatures. 8.3 Regreasing roller bearings Refer to the regreasing instructions for the roller bearings on the lubricant plate. 8.4 Stoppages The stoppage is a shutdown for a period of time, during which the machine is stopped but remains at the location of use. Under normal ambient conditions, e. g. the stopped machine is not exposed to any vibration, no increased level of corrosion, etc. in general, the following measures are necessary during stoppages. NOTICE Damage due to improper storage Damage may occur to the motor if it is not stored properly. If the machine is to be taken out of operation for more than 12 months, suitable anti-corrosion, preservation, packaging, and drying measures must be taken. See also Transport (Page 34) Start-up (Page 91) SIMOTICS FD 1LM1 Operating Instructions 01/2019 107 Operation 8.4 Stoppages 8.4.1 Avoidance of condensation or formation of condensation within the machine If the controller does not do this automatically, switch on any anti-condensation heating during stoppages. This will avoid the formation of condensation. Do not switch on the anti-condensation heating for at least two hours after the motor has been switched off. This prevents damage to the winding insulation. 8.4.2 Avoidance of damage to roller bearings during stoppages Extended stoppages at the identical or almost identical resting position of the roller bearings can lead to damage such as brinelling or corrosion, for example. During stoppages, regularly start the machine up for a brief period once a month. As a minimum, rotate the rotor several times. If you have uncoupled the machine from the driven machine and secured the rotor with a rotor shipping brace, then remove this before turning the rotor over or starting the machine up. Make sure that the resting position of the roller bearings after the rotor has been turned over is different from what it previously had been. Use the fitted key or the coupling halves as reference markers. During re-commissioning, refer to the information in the "Commissioning" section. See also Start-up (Page 91) 8.4.3 Measurement of the insulation resistance after an extended stoppage Measuring the insulation resistance and polarization index (PI) provides information on the condition of the machine. It is therefore important to check the insulation resistance and the polarization index at the following times: Before starting up a machine for the first time After an extended period in storage or downtime Within the scope of maintenance work The following information is provided regarding the state of the winding insulation: Is the winding head insulation conductively contaminated? Has the winding insulation absorbed moisture? As such, you can determine whether the machine needs commissioning or any necessary measures such as cleaning and/or drying the winding: Can the machine be put into operation? Must the windings be cleaned or dried?

You can burn yourself if you touch hot surfaces. Allow the machine to cool before starting any maintenance and service work on the machine. Check the temperature of parts before touching them. If required, wear suitable protective equipment. Damage if the machine is not maintained The machine can be damaged if it is not appropriately maintained. This can cause faults which can result in eventual or immediate death, serious injury or material damage. Maintain the machine at the specified maintenance intervals. Damage from foreign bodies in the machine Foreign bodies such as dirt, tools or loose components can be left by accident inside the machine after maintenance is performed. These can cause short circuits, reduce the performance of the cooling system or increase noise in operation. They can also damage the motor. Ensure that no foreign bodies are left in or on the motor. Securely attach all loose parts once you have completed the work. Carefully remove any dirt. 114 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Maintenance 9.1 Inspection and maintenance 9.1.2 Measuring the insulation resistance during the course of maintenance work Measuring the insulation resistance and polarization index (PI) provides information on the condition of the machine. It is therefore important to check the insulation resistance and the polarization index at the following times: Before starting up a machine for the first time After an extended period in storage or downtime Within the scope of maintenance work The following information is provided regarding the state of the winding insulation: Is the winding head insulation conductively contaminated? Has the winding insulation absorbed moisture? As such, you can determine whether the machine needs commissioning or any necessary measures such as cleaning and/or drying the winding: Can the machine be put into operation? Must the windings be cleaned or dried? Detailed information on testing and the limit values can be found here: "Testing the insulation resistance and polarization index" (Page 51) 9.1.3 Inspections in the event of faults Natural disasters or unusual operating conditions, such as overloading or short circuit, are faults that overload the machine electrically or mechanically. Immediately perform an inspection after such faults. 9.1.4 First service after installation or repair Perform the following checks after approximately 500 operating hours or at the latest six months after commissioning: Table 9-1 Checks after assembly or repair Check When the motor is running The stated electrical characteristics are being observed.

If it is defective, contact the Service Center (Page 157). 9.1.7 Assessing the roller bearings To assess the roller bearings, it is generally not necessary to dismantle the machines. The motor only has to be dismantled if the bearings are to be replaced. The state of a roller bearing can be assessed by analyzing the bearing vibration. The measured values provide an indication and can be assessed by specialists. Contact the Service Center. 9.1.8 Roller bearings with automatic regreasing system The roller bearings are supplied with new grease by the regreasing system. Replace the grease cartridge timely. Observe the operating instructions for the regreasing system when replacing the grease cartridges. See also Interlock circuit for the automatic regreasing system (option) (Page 31) Only use the grease that is specified on the lubricant plate. 9.1.9 Regreasing intervals and types of grease for operating roller bearings The specified grease data applies to the data specified on the rating plate and for high-quality grease in accordance with the specifications in these operating instructions. Because these greases exceed significantly the requirements according to DIN 51825 and ISO 67439, they permit the specified relubrication intervals. Initial lubrication The grease specified on the lubricant plate is selected according to the operating conditions known at the time of ordering and should be used for initial lubrication. SIMOTICS FD 1LM1 Operating Instructions 01/2019 117 Maintenance 9.1 Inspection and maintenance Criteria for selecting rolling bearing greases High quality ISOLX BDEA3 lubricating grease according to ISO 6743-9 and K3K20 lubricating grease according to DIN 51825 with lithium soap as a thickener and an upper service temperature of at least +130 C / +266 F are permissible for standard applications without special requirements. The technical data of the rolling bearing grease must be suitable for the application. Only use the grease type that is specified on the lubricant plate. If the operating conditions differ from those mentioned, other lubricating greases may only be used after prior consultation with the manufacturer. If lubricating greases other than those named on the lubricant plate are used, it cannot be guaranteed that they are compatible with the complete system. - If you use lubricating greases that satisfy only the minimum requirements of DIN 51825 or ISO 6743-9, then reduce the lubrication intervals by half or adapt them as appropriate. - If in doubt, consult the manufacturer. The lubrication properties will be impaired if you mix different lubricating greases. This can result in material damage. Only the manufacturer can provide a guarantee for the miscibility of particular lubricating greases. The lubricating grease must satisfy the criteria listed in the table below and must match the operating conditions. If different special lubricating greases are stated on the lubricant plate, then different criteria apply. Table 9-3 Criteria for selecting rolling bearing greases Criteria Standard Property, characteristic value Unit Type of base oil - Mineral oil - Thickener - Lithium - Consistency in accordance with NLGI class DIN 51818 "3" for vertical and horizontal types of construction - "2" alternatively for horizontal type of construction with reduced lubrication interval Operating temperature range - At least -20 C ... +130 C C Dropping point DIN ISO 2176 At least +180 C C Basic oil viscosity DIN 51562-1 Approx. 100 mm/s at 40 C mm/s Approx. 10 mm/s at 100 C Additives - Anti-Oxidation (AO), Anti-Wear (AW) - No solid lubricants Alternatively: Extreme-pressure (EP) only after prior consultation with grease and bearing manufacturers FE9 test: A/1500/6000 DIN 51821-1/-2 F10 50 h at +130 C H F50 100 h at +130 C Behavior in the presence of water DIN 51807 0 or 1 at a test temperature of +90 C - Corrosive effect on copper DIN 51811 0 or 1 at a test temperature of +120 C Korr. 118 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Maintenance 9.1 Inspection and maintenance Criteria Standard Property, characteristic value Unit Corrosion resistance (EMCOR) DIN 51802 / 0-0 Korr.

However, this reduces the lubrication interval by 20%. Table 9-5 Alternative greases with NLGI class 2 for motors of horizontal construction Manufacturer Grease type Shell Gadus S2 V100 2 ExxonMobil/Esso Unirex N2 BP Energrease LS2 Castrol Longtime PD2 Lubcon Turmogrease L 802 EP plus Shell Retinax LX2 FAG Arcanol Multi 2 Lubrication data The following data is provided on the lubricant plate of the machine. Regreasing intervals in operating hours Regreasing amount in grams Grease type SIMOTICS FD 1LM1 Operating Instructions 01/2019 119 Maintenance 9.1 Inspection and maintenance Grease replacement intervals The grease replacement intervals in these operating instructions or the regreasing intervals indicated on the plate apply to the following conditions: Normal load Operation at speeds in accordance with rating plate Low-vibration operation Neutral ambient air High-quality rolling bearing greases In the case of unfavorable operating conditions, reduce the relubrication intervals after prior consultation with the manufacturer. Regreasing rolling bearings Regrease the rolling bearings at the latest every 12 months irrespective of the actual number of operating hours. The regreasing intervals for rolling bearings differ from the service intervals for the machine. The rolling bearings may be damaged if the relubrication intervals are not complied with. Pay attention to the instructions on the lubricant plate. 1. Clean the grease nipple. 2. Rotate the shaft when regreasing, so that the new grease can be distributed throughout the bearing. Motors that are operated with converters: Regrease the bearings at a low to medium speed (nmin = 250 rpm, nmax = 3600 rpm) to ensure an even distribution of grease. WARNING Risk of injury due to rotating parts The shaft must rotate to allow the grease to be distributed. This can result in death, serious injury or material damage. When regreasing, pay attention to all rotating components. 3. Gradually press in an appropriate type and amount of grease, as stamped on the lubricant plate and specified in these operating instructions - max. 50 g per 30 min. The rolling bearing temperature rises sharply at first, then drops to the normal value again when the excess grease is displaced out of the bearing. The used grease collects outside each bearing in a spent grease chamber. Greasing the rolling bearings prior to commissioning When properly stored prior to commissioning for a longer period of time, normally the grease in the bearings does not deteriorate within two years. When commissioning, the bearings must be relubricated with twice the amount of lubricating grease. When doing this, the shaft must rotate so that the grease is replaced in the bearings. Carefully observe the information relating to long-term storage. 120 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Maintenance 9.1 Inspection and maintenance 9.1.10 Sealing the rolling-contact bearings ("Increased degree of protection" option) Relubricating the grease tank In order to achieve optimum sealing of the rolling contact bearings and to reliably seal the labyrinth joints with grease, the chamber must be relubricated at regular intervals. The procedure is the same as that for lubricating grease. The sealing effect during operation is optimum as long as a small amount of relatively clean grease is forced out. Regreasing intervals The necessary relubrication intervals depend essentially on the level of dirt in the environment and on the ON time of the motor. For this reason, they can only be defined taking into account the respective operating conditions. Make sure that the groove in the seal is full of grease at all times. 9.1.11 Cleaning the cooling air ducts The cooling ducts must be free of any pollution in order that the machine is adequately cooled. Regularly clean the grids, ducts, ribs, pipes etc. to remove dust and pollution. 9.1.12 Replacing a filter mat 1. Switch off the motor while changing a filter. 2. When replacing a filter, wear protective overalls, a mask to provide protection against fine dust as well as protective eyewear and gloves. 3. When replacing the filter mats, check the inner and outer cages for damage. Identify the cause if there are signs of moisture, condensation or corrosion. 4. Only use unused filter mats that are in perfect condition. CAUTION Used or dried filter mats Used filter mats can be polluted with hazardous substances or concentrations of microorganisms that can damage the health. Used filter mats or filter mats that have dried again represents a health hazard. Do not use wet or moist filter mats. Immediately dispose of used or dried filter mats. Do not store used filter mats in areas where they can come into contact with fresh filter mats or can cause health hazards, e.g. in the vicinity of foodstuffs. Do not use used filter mats or those that appear to be able to still be used in other areas. SIMOTICS FD 1LM1 Operating Instructions 01/2019 121 Maintenance 9.1 Inspection and maintenance 9.1.13 Installing filter mats 1. Screw the inner cage to the machine. 2.

Spares on Web (https://www.sow.siemens.com/). See also Guide for Spares on Web (http://support.automation.siemens.com/WW/news/en/25248626) Rolling bearings When ordering rolling bearings, in addition to the bearing identification code, the supplementary specifying code is also necessary for the bearing version. Both of these codes are stamped on the lubricant plate and specified in the motor documentation, or can also be taken from the installed bearings. Always replace the rolling bearings with the identical bearings. If insulated rolling bearings are fitted, use insulated rolling bearings of the same type as spare parts. This will prevent any bearing damage being caused by bearing currents. 10.3 Anti-condensation heating The anti-condensation heater is mounted directly on the winding. The anti-condensation heater cannot be removed without causing damage to the winding. A new anti-condensation heater may only be installed by Siemens Service Center (Page 157) specialists. 134 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Spare parts 10.4 Housing, stators and rotors 10.4 Housing, stators and rotors Figure 10-1 Table 10-1 Housing, stators and rotors Spare parts for housing, stators and rotors Part Description 5.41 Gill plate and cover for air discharge opening 5.49 Enclosure cover 8.00 Rotor, complete 8.20 Stator core with winding 10.00 Stator frame 10.50 Lifting lugs 20.00 Terminal box without cable entry See also Terminal box 1XB1621 (Page 142) Terminal box 1XB1631 (Page 144) Terminal box 1XB7730 (Page 145) Terminal box 1XB7731 (Page 146) SIMOTICS FD 1LM1 Operating Instructions 01/2019 135 Spare parts 10.4 Housing, stators and rotors Terminal box 1XB7740 (Page 147) Terminal box 1XB7750 (Page 148) 136 SIMOTICS FD 1LM1 Operating Instructions 01/2019 Spare parts 10.5 Ventilation 10.5 Ventilation Table 10-2 Spare parts for ventilation Part Description 11.00 External fan 12.00 Complete fan cowl SIMOTICS FD 1LM1 Operating Instructions 01/2019 137 Spare parts 10.6 Air filter 10.6 Air filter Table 10-3 138 Spare parts air filter Part Description 34.30 Spare part kit filter 34.32 Filter mat SIMOTICS FD 1LM1 Operating Instructions 01/2019 Spare parts 10.7 Roller bearing cartridge at the drive and non-drive end 10.7 Roller bearing cartridge at the drive and non-drive end Figure 10-2 Bearing cartridge at the drive end and non-drive end Table 10-4 Spare parts for the bearing cartridge at the drive end and non-drive end Part Description Part Description 3.20 Outer bearing cover 4.20 Outer bearing cover 3.35 Grease slinger 4.35 Grease slinger 3.60 Inner bearing cover 4.60 Inner bearing cover 5.00 End shield 6.00 End shield Bearing kit at the drive end and non-drive end consists of the following components Deep-groove ball bearing (locating bearing) Deep-groove ball bearings Shaft sealing ring, labyrinth ring (optional) Shaft sealing ring Locking ring, guard ring Locking ring SIMOTICS FD 1LM1 Operating Instructions 01/2019 139 Spare parts 10.8 Roller bearing cartridge at the drive and non-drive end 10.8 Roller bearing cartridge at the drive and non-drive end The following description applies to the standard version for IM B3.

Always renew keyed elements. When screwing together threads secured with a liquid adhesive, use a suitable medium such as Loctite 243. Always use suitable securing devices or removable adhesives (e.g., Loctite 243) when installing fixing bolts with a clamping length of less than 25 mm. The clamping length is taken as the distance between the head of the bolt and the point at which the bolt is screwed in. Tightening torques The bolted connections with metal contact surfaces, such as end shields, bearing cartridge parts, terminal box parts bolted onto the stator frame, should be tightened to the following torques, depending on the thread size: Table B-1 Tightening torques for bolted connections with a tolerance of 10%.
