Detailed instruction of parameters
The setting range of P04.01:0.0%:(automatic) 0.1%~10.0%
The setting range of P04.02:0.0%~50.0%
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 damage.
Overcurrent stall or overcurrent protection may occur.
The setting range of P04.03: 0.00Hz~P04.05
The setting range of P04.04, P04.06 and P04.08 :
0.0%~110.0% (rated motor voltage)
The setting range of P04.05: P04.03~ P04.07
The setting range of P04.07: P04.05~P02.02 (rated motor
voltage frequency)
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 -n*p/60
b
Of which, f is the rated frequency of the motor, its function
b
code is P02.02; n is the rated rotating speed of the motor
and its function code is P02.03; p is the pole pair of the
motor. 100.0% corresponds to the rated slip frequency △ f.
