Torque Compensation Function

This function increases the output torque of the Inverter by detecting an increase in the
motor load.
n103
Torque Compensation Gain
Setting 0.0 to 2.5
range
Set Values
• The default setting does not need any changes in normal operation.
• Change the default setting in the following cases.
The wiring distance between the Inverter and motor is long:
Set the gain to a larger value.
The capacity of the motor is lower than the maximum applicable motor capacity of the Inverter:
Set the gain to a larger value.
The motor vibrates:
Set the gain to a smaller value.
• The torque compensation gain must be adjusted so that the output current at low speed will not exceed
50% of the rated output current of the Inverter, otherwise the Inverter may be damaged.
n104
Torque Compensation Primary
Delay Time Constant
Setting 0.0 to 25.5 (s)
range
Note The default value is 0.2 (s) with the Inverter set to vector control mode.
Set Values
• This parameter is used for adjusting the response of torque compensation.
• Normally, the default setting does not need to be changed.
• Adjust the parameter in the following cases.
The motor vibrates: Increase the set value.
The response of the motor is slow: Decrease the set value.
n105
Torque Compensation Core Loss
Setting 0.0 to 6,550 (W)
range
Note 1. The value will be set in 0.1-W increments if the loss is less than 1,000 W and 1-W increments if
the loss is 1,000 W or over.
Note 2. The default setting varies with the capacity of the Inverter model.
