This parameter may be set so that the AC motor drive will increase its voltage output to obtain

 

a higher torque. Only to be used for SVC control mode.

 

 

Too high torque compensation can overheat the motor.

When the asynchronous motor is driven by the drive, the load and slip will be increased. This parameter can be used to correct frequency and lower the slip to make the motor can run near the synchronous speed under rated current. When the output current is larger than the motor no-load current, the drive will compensate the frequency by Pr.05-25 setting. If the actual speed is slower than expectation, please increase the setting and vice versa.

It is only valid in SVC/VF mode.

The factory settings are:

A. In SVC mode, the factory setting is 1.00.

B. In VF mode, the factory setting is 0.00.
