Setting range of P04.01: 0.0%: (automatic) 0.1%–

Setting range of P04.02: 0.0%–50.0%
P04.03
V/F frequency
point 1 of motor 1
When P04.00 =1 (multi-point V/F curve), users can
set V/F curve via P04.03–P04.08.
V/F curve is usually set according to the
characteristics of motor load.
Note: V1<V2<V3, f1<f2<f3. If low-frequency
voltage is set too high, motor overheat or
burnt-down may occur, and overcurrent stall or
overcurrent protection may occur to the VFD.

This parameter is used to compensate for the motor
rotating speed change caused by load change in
the SVPWM mode, and thus improve the rigidity of
