F4.03~F4.08 are used to set the user-defined V/F
curve. The value should be set according to the
load characteristic of motor.

【 0.0% 】
The slip compensation function calculates the
torque of motor according to the output current
and compensates for output frequency. This
function is used to improve speed accuracy when
operating with a load. F 4.0 9 sets the slip
compensation limit as a percentage of motor rated
slip; the slip compensation limit is calculate d as
the formula:
F 4.09=fb-n*p/60
Fb = Motor rated frequency (F 2.0 2)
N = Motor rated speed (F2.03)
P= Motor poles
