When P04.00 =1, the user can set V//F curve
through P04.03
–P04.08.
V/F is generally set according to the load of the
motor.

frequency voltage will heat the motor excessively or
cause damage. The VFD may stall when overcurrent
or overcurrent protection.

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*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
