Function

These parameters are used to jump resonant frequencies to avoid resonance with the natural frequency of the mechanical equipment operated. In jump mode, the motor exhibits hysteresis with respect to the jump frequency.

If the upper limit frequency () is within a jump frequency range, it is limited to the lowest frequency in the jump frequency range.

If the lower limit frequency () is within a jump frequency range, it is limited to the highest frequency in the jump frequency range.

Do not overlap upper limit freqency () and lower limit frequency () within a jump frequency range. If they are overlapped,it is operated lowest jump frequency.

Do not overlap two or more jump frequency ranges,or it cannot be operated within normal range.

The operation frequency is not jumped during acceleration or deceleration.
