Torque Compensation Function
Chapter 6-5
Set Values n61
Setting range
0.1 to 10.0 (s)
Set the parameter as percentage based on the rated Inverter current as
100%.
Overtorque Detection Time No
Unit of setting
0.1 s
Changes during operation
Default setting 0.1
Set Values • Set the overtorque detection time.
• The Inverter will detect overtorque when the current the same as or higher than the detection level is output for the preset detection time.

6-5 Torque Compensation Function
This function increases the output torque of the Inverter by detecting an increase in the motor load.
n63
Setting range
0.0 to 2.5
Torque Compensation Gain
Unit of setting
0.1
Changes during operation
Default setting 1.0
Yes
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.
