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:
△f=fb-n*p/60
where fb is the rated frequency of motor 2,
corresponding to P12.02; n is the rated speed of
motor 2, corresponding to P12.03; p is the number
of pole pairs of motor 2. 100% corresponds to the
rated slip frequency △f of motor 2.
Setting range: 0.0–200.0%
Low-frequency
oscillation control
factor of motor 2
In the SVPWM mode, current oscillation may easily
occur on motors, especially large-power motors, at
some frequency, which may cause unstable running
of motors or even overcurrent of VFDs. You can
modify this parameter to prevent current oscillation.
Setting range of P04.23: 0–100
Setting range of P04.24: 0–100
Setting range of P04.25: 0.00 Hz–P00.03 (Max.
