V/F slip
compensation
gain of motor 2
This parameter is used to compensate for the motor
rotating speed change caused by load change in the
SVPWM mode, and thus improve the rigidity of the
mechanical characteristics of the motor. You need to
calculate the rated slip frequency of the motor as
follows:
0.0%
