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%
