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 V/F 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 V/F 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 properly to eliminate such
phenomenon.
