Common Specifications
Note: 1.
The applicable motor is a 3-phase standard motor. For using any other type, be sure that the rated current does not exceed that of the Inverter.
2. Output voltage decreases according to the level of the power supply voltage.
3. The braking torque at the time of capacitor feedback is an average deceleration torque at the shortest deceleration (when it stops from
50 Hz). It is not a continuous regeneration torque. Also, the average deceleration torque varies depending on the motor loss. The value
is reduced in operation over 50 Hz.
*1. Protection method complies with JEM 1030.
*2. To operate the motor at over 50/60 Hz, contact the motor manufacturer to find out the maximum allowable speed of revolution.
*3. For the stable control of the motor, the output frequency may exceed the maximum frequency set in A004 (A204) by 2 Hz max.
