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
b
-n*p/60
Of which, f
b
is motor rated frequency, corresponding to the function code P02.02; n is motor rated speed,
corresponding to the function code P02.03; p is motor pole pair, 100.0% corresponding to the rated slip

Under V/F control mode, especially the motor with big power, current oscillation may occur to some
frequency, causing unstable running of the motor or even VFD overcurrent. Eliminate the results by
adjusting the parameters properly.
