P04.05
V/F
frequency
point 2
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.
Setting range of P04.03: 0.00Hz–P04.05
Setting range of P04.04, P04.06 and P04.08:
0.0%–110.0% (rated motor voltage)

V/F slip
compensat
ion gain
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 x 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 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%

frequency
vibration
control
factor
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.
