Description
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
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)
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
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,
b
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
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
adjusting this parameter.
Setting range of P04.10: 0–100
Setting range of P04.11: 0–100
