Detailed instruction of parameters
Setting range of P04.05: P04.03– P04.07
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 x p/60
b
Of which, f is the rated frequency of the motor, its
b
function 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.
Setting range: 0.0–200.0%
In the SVPWM control mode, current fluctuation may
occur to the motor on some frequency, especially the
motor with big power. The motor can not run stably or
overcurrent may occur. These phenomena can be
canceled by adjusting this parameter.
Setting range of P04.10: 0–100
Setting range of P04.11: 0–100
Setting range of P04.12: 0.00Hz–P00.03 (the Max.
frequency)
0: No operation
1: Automatic energy-saving operation
Motor on the light load conditions, automatically adjusts
the output voltage to save energy
Select the output setting channel at V/F curve
separation.
0: Keypad setting voltage: the output voltage is
determined by P04.28.
