P04.09
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.
Setting range: 0.0–200.0%

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, you can adjust these two parameters
properly to eliminate such phenomenon.
Setting range of P04.10: 0–100
