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 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 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 V/F 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 inverters.
