• When the set frequency is increased and the set frequency enters the jump frequency band, the in-
ternal set frequency is kept constant at the lower limit of the jump frequency band. If the set frequen-
cy exceeds the upper limit of the jump frequency band, the internal set frequency reaches the value
of the set frequency. When the set frequency is reduced, the opposite relationship to that during in-
crease is realized.

• If two or more jump frequency ranges overlap each other, the lower limit value and the upper limit
value of the overlapped jump frequency become the lower limit and upper limit frequencies of the
actual jump frequency range.

During acceleration and deceleration, the output frequency changes continuously in accordance with
the acceleration/deceleration time.
Although the jump frequency can be set at three locations, the jump frequency width is common at the
three locations.
