voltage for low frequency will cause motor
overheat or damage and cause VFD
overcurrent stall or overcurrent protection.

V/F slip
compensati
on gain
This function code is used to compensate for
the motor rotating speed change caused by
load change in SVPWM control mode, and
thus improve the mechanical characteristics
of the motor. You need to calculate the rated
slip frequency of the motor as follows:
