Encoder origin designation The process display angle can be set to the origin as 0 at the press of a button. Angle display switch The unit can convert the display of absolute encoder values 256 divisions/revolution to 360/revolution. Rotation display monitor Graphic display of encoder rotational angle position. Teaching The unit can set the ON/OFF angle from actual operation of the machine. Monitor contents Process value display (character height: 11 mm), output display, settings display, set cam number display, mode display, revolution display, operation step display, and error message display. Operation The H8PS Cam Positioner receives angle signal inputs from the Encoder, and outputs the preset ON/OFF angles as control signals (cams number 1 to 8). Program Example Control output STEP 1 (cam number) ON angle STEP 2 OFF angle ON angle OFF angle 1 45 180 --- --- 2 0 90 180 270 . . . . . . . . . . . . . . . 8 135 225 315 45 Operation Example Note: 1. When the setting angles for STEP 1 and STEP 2 of same output are overlapped, the operation is as follows: 2. The operating output "RUN OUT" does not turn ON during programming. The operation output turns ON with the timing shown in the diagram, but it remains OFF when an error occurs. Thus, you can use the output as a timing signal during operation, including test runs. 5 H8PS H8PS Initializing Actual Setting Example 1.

Precautions Cam Positioner Error Displays and Cancelling When an error occurs, perform the following cancellation operation. (When the following errors occur, all outputs turn OFF except for the TACHOMETER output.) Display Description Cancellation method Set origin data error Reset the origin in the Programming Mode and return to the previous mode. Memory error, when settings have been modified Switch to the Programming Mode and confirm all settings. After correcting the settings, return to the previous mode. Encoder input data error Switch to the Programming Mode and check the following items. Return to the previous mode after corrections. 1. The Encoder is malfunctioning or a connector is disconnected. 2. The Encoder rotation speed exceeds the response limit. 3. The Encoder output data became scrambled because of noise. 1. Encoder abnormality 2. Faulty Encoder connector contacts 3. Encoder rotation speed and response speed settings 4. Noise and surge protection 4. A line to the Encoder is cut. 13 H8PS H8PS The external finish of the main unit is prone to organic solvents (thinner, benzene, etc.), strong alkali (ammonia, sodium hydroxide), and strong acid. Please avoid contact with theses chemicals. Store the devices between -25C and 65C. For storage below -10C, power the unit up after letting it stand at room temperature for three hours. To perform dielectric testing, impulse-voltage testing, and insulation-resistance measuring between the electrical circuitry and the uncharged metal parts when the unit is mounted in a control panel, first disconnect the wiring of the unit from the circuitry. (This prevents degradation of damage of internal circuitry in the event that part of the control-panel equipment has faulty voltage resistance or faulty insulation. The test voltage might go to the power-supply terminals of the main unit.) The Encoder consists of precision parts. Exercise care in handling, and make sure no excessive shock or pressure is applied to the Encoder. Especially make sure that the Encoder's rotating shaft is not subjected to excessive force. The connections for the main unit connectors should have no undue stress applied. Wire cables accordingly. After turning on the power, it takes approximately two seconds until normal operation, When the ON angle and OFF angle are the same value, no output will occur. Handling Turn the operation power on or off instantaneously via a contact such as a switch or relay. Avoid operation in the following environments: 1. An ambient temperature below -10C or above 55C. 2. Very dusty locations. 3. Very humid locations. 4. Locations where corrosive gasses are generated. 5. Locations with heavy vibrations or shock. 6. Locations prone to water or oil. 7. Locations with direct sunlight. For operation in environments with excessive electrical noise generation, separate the Encoder cords and the main unit of the H8PS from high-power cables that have noise or noise-generating sources. How to Use the Table Angle Data Table The H8PS uses an absolute Encoder with 256 divisions per revolution. To assist with programming, displays and settings may be done by conversion to 360 degrees by a switch on the front panel. The following table shows the conversions. 0 1 256 display (Encoder output data) 0 1 360 display (360 converted data) 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0 1 3 4 6 7 8 10 11 13 14 15 17 18 20 21 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 23 24 25 27 28 30 31 32 34 35 37 38 39 41 42 44 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 45 46 48 49 51 52 53 55 56 58 59 60 62 63 65 66 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 293 294 295 297 298 300 301 302 304 305 307 308 309 311 312 314 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 315 316 318 319 321 322 323 325 326 328 329 330 332 333 335 336 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 338 339 340 342 343 345 346 347 349 350 352 353 354 356 357 359 WARNING 1. The H8PS has a built-in lithium battery. Be sure to dispose of the old H8PS properly, as lithium batteries are likely to explode if incinerated. 2. Electrical shock hazard Never touch the input terminals of any H8PS Cam Positioner when power is being applied to the Cam Positioner. 14 H8PS H8PS Rotary Encoder Make sure that the E6CP Encoder is not subjected to oil or water. If oil or water enters the interior, malfunctions may occur. For use in environments subject to water drops or oil, use the E6F. Rotary Encoders consist of precision parts. Their operation may be damaged if the Encoder is dropped. Be very careful with handling. When joining to a chain, timing belt, or gears, interpose a coupling and bearings before the Encoder. Large mounting deviations (eccentric centers or angles) may cause an excessive load on the Encoder's shaft, resulting in damage or drastically reduced life expectancy. Take care not to place excessive loads on the shaft. Keep the tightening torque around 5 kg S cm when fastening the rotary Encoder. Do not pull the wiring at a force greater than 3 kg when the main unit is fastened and wired. If you insert a coupling on the shaft, do not hammer on the coupling or otherwise subject it to shock. Mounting Procedure 1. Place a coupling on the shaft. Do not screw the coupling and shaft tight. 2. Fasten the Encoder. Do not insert the shaft to the coupling more than the length shown below. Shaft coupling Length of insertion E69-C06B 5.5 mm E69-C10B 7.1 mm 3. Fasten the coupling. Shaft coupling Tightening torque E69-C06B 2.5 kgf S cm E69-C10B 4.5 kgf S cm 4. Connect power supply and input/output lines. Make sure you turn off the power supply when wiring. 5. Turn on the power and check outputs. 15 H8PS H8PS ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
