V/F slip
compensation
gain
This function code is used to compensate the change of
the rotation speed caused by load during compensation
SVPWM control to improve the rigidity of the motor. It
can be set to the rated slip frequency of the motor which
is counted as below:
△
f=f
b
-n x p/60
Of which, f
b
is the rated frequency of the motor, its
function code is P02.02; n is the rated rotating speed of
the motor and its function code is P02.03; 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 can not run stably or
overcurrent may occur. These phenomena can be
canceled by adjusting this parameter.
