V/F slip
compensation
gain
This function code is used to compensate the
motor rotation speed change caused by load
change during SVPWM control to improve the
rigidity of the motor. The rated slip frequency of
the motor needs to be calculated.

Of which, f
b
is the rated frequency of the motor,
its function code is
. n is the rated rotating
speed of the motor and its function code is
. p is the pole pair of the motor. 100.0%
corresponds to the rated slip frequency

P04.10
Low frequency
vibration control
factor
In the SVPWM control mode, current fluctuation
may occur to the motor on some frequency,
especially the motor with big power. The motor
cannot run stably or overcurrent may occur.
These phenomena can be canceled by adjusting
the parameters.
