Description
0～2000
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.
Oscillation suppression effective
range :100%～1200%
Set the range of the oscillation
suppression function, 100%
corresponds to the rated frequency of
the motor
0：ineffective
1：only adjust output voltage (Current
limiting for general VF separation)
2：adjust output frequency
20%～180% drive rated current
0.50-2.00 optimize dynamic
performance of Weak magnetic zone
100%~130%, increasing this
parameter can improve the load
capacity of VF control in the weak
magnetic area.
