V/F slip
compensation
gain of motor 1
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:
△
f=fb-n×p/60
where fb is the rated frequency of motor 1,
corresponding to P02.02; n is the rated speed of
motor 1, corresponding to P02.03; p is the number of
pole pairs of motor 1. 100% corresponds to the rated
slip frequency
△
f of motor 1.

P04.10
Low-frequency
oscillation control
factor of motor 1
Under SVPWM control mode, the motor, especially
the large-power motor may experience current
oscillation during certain frequencies, which may
lead to unstable motor operation, or even inverter
overcurrent, users can adjust these two parameters
