Current oscillation is prone to occur when the motor is running at certain frequency
segments, the light is to cause the motor instable running, and the serious is to cause inverter
overcurrent. When F8.04=0, enable vibration suppression function
，
when the set of F8.00, F8.01
is small, oscillation restraining effect and current increasing is obvious, and when the set of
F8.00, F8.01 is large, oscillation restraining effect is weak.
