01-10 Torque compensation gain
Range
0.0~2.0
In V/F or V/F + PG and SLV2 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.
Torque compensation gain (01-10) can adjust in the running time. No need to adjust in general except the
following:
If the wire between inverter and motor is too long, add the value of 01-10
If the capacity of motor is smaller than inverter, add the value of 01-10.
If the motor vibrates, reduce the value of 01-10
Refer to the torque compensation gain adjustment shown in Figure 4.4.14.
Figure 4.4.14 Torque compensation gain to increase/decrease output torque
Increase value when:
The wiring between the inverter and the motor very 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.
01-11 Selection of Torque Compensation Mode
Range
0: Torque Compensation Mode 0
1: Torque Compensation Mode 1
Torque compensation mode 0 is the general mode.
Torque Compensation Mode 1 is the high speed mode (120~160Hz) and the compensation amount decreases as
