When P04.00=1 (multi-dot V/F curve), set the V/F curve by P04.03~P04.08.
The V/F curve is usually set according to the load feature of the motor.
Note: V1<V2<V3, f1< f2<

compensation gain
This function code is used to compensate the change of the rotating speed caused by the change of load
at V/F control to improve mechanical rigidity of the motor. The rated slip frequency of the motor should be
calculated as follows:
△
f=f -n*p/60
b
Of which, f is motor rated frequency, corresponding to the function code P02.02; n is motor rated speed,
b
corresponding to the function code P02.03; p is motor pole pair, 100.0% corresponding to the rated slip
△
frequency f.
