Torque Compensation Gain
Range
【
0.0~2.0】
In V/F mode the inverter automatically adjusts the output voltage to adjust the output torque during start or
during load changes based on the calculated loss of motor voltage.
The rate of adjustment can be changed with the torque compensation gain parameter.
Refer to the torque compensation gain adjustment shown in Figure 4.4.11.
Figure 4.4.11 Torque compensation gain to increase/decrease output torque
Increase value when:
The wiring between the inverter and the motor is too long
The motor size is smaller than the inverter size
Note: Gradually increase the torque compensation value and make sure the output current does not
exceed inverter rated current.
Reduce value when:
When experiencing motor vibration
Important:
Confirm that the output current at low speed does not exceed the rated output current of the inverter.

Selection of Torque Compensation Mode
Range
0: Torque Compensation Mode 0
1: Torque Compensation Mode 1
01-11=0: General torque compensation mode.
01-11=1: High-speed torque compensation mode (120~160Hz).
Compensation amount decreases as the frequency increases. Compensation in 0~120Hz is the same as
that in torque compensation mode 0.
