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.
Note:V1<V2<V3,f1<f2<f3. Too high low
frequency voltage will heat the motor excessively or
cause damage. The inverter may stall when
overcurrent or overcurrent protection.
The setting range of P04.03: 0.00Hz~P04.05
The setting range of P04.04:0.0%~110.0%
The setting range of P04.05:P04.03~ P04.07
The setting range of P04.06:0.0%~110.0%(the rated
voltage of motor 1)
The setting range of P04.07:P04.05~ P02.02(the
rated frequency of motor 1) or P04.05~ P02.16(the
rated frequency of motor 1)
The setting range of P04.08:0.0%~110.0%(the rated
voltage of motor 1)
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
