Torque Compensation Function
Chapter 6-5
Set Values Set the parameter as percentage based on the rated Inverter current as
100%.
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.
#
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.
