☆ 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 the upper limit freqency (

) and the lower limit
frequency (

) within a jump frequency range. If they overlap, 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.

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.
