This function is only active when P4.00 is set to be 1. P4.03~P4.08 are used to set the
user-defined V/F curve. The value should be set according to the load characteristic of
motor.

The motor
’
s slip changes with the load torque, which results in the variance of motor
speed. The inverter

s output frequency can be adjusted automatically through slip
compensation according to the load torque. Therefore the change of speed due to the
