P4.03 V/F FREQ 1 0.00Hz~ P4.05 0.00~P4.05 5.00Hz
P4.04 V/F VOLTAGE 1 0.0%~100.0% 0.0~100.0 10.0%
P4.05 V/F FREQ 2 P4.03~ P4.07 P4.03~ P4.07 30.00Hz
P4.06 V/F VOLTAGE 2 0.0%~100.0% 0.0~100.0 60.0%
P4.07 V/F FREQ 3 P4.05~ P2.01 P4.05~ P2.01 50.00Hz
P4.08 V/F VOLTAGE 3 0.0%~100.0% 0.0~100.0 100.0%
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.
Notice:
 0 ＜ V1 ＜ V2 ＜ V3 ＜ rated voltage.
 0 ＜ f1 ＜ f2 ＜ f3 ＜ rated frequency.
 The voltage corresponding to low frequency should not be set too high,
otherwise it may cause motor overheat or inverter fault.
