■ Function
When you want to avoid resonance caused by the natural frequency of the mechanical system to
run the inverter, the resonant frequency can be jumped.
This characteristic has hysteresis given to the jump frequency.
■ Parameter setting
■ Setting method
You can set three jump frequencies. To do that, avoid the overlap of the adjustment range of each
jump frequency.
The frequency does not jump during acceleration or deceleration.
