2 .3.16 Frequency jump to
When it is desired to avoid
resonance attributable to the
natural frequency of a mechanical
system, these parameters allow
resonant frequencies to be
jumped. Up to three areas may be
set, with the jump frequencies set
to either the top or bottom point of
each area.

Setting is enabled when
Pr. 30 = "1"
To fix the frequency at 30Hz between Pr. 33 and Pr. 34
(30Hz and 35Hz), set 30Hz in Pr. 33 and 35Hz in Pr. 34. Pr.34:35Hz
Pr.33:30Hz
To jump to 35Hz between 30 and 35Hz, set 35Hz in
Pr. 33 and 30Hz in Pr. 34.
Pr.33:35Hz
Pr.34:30Hz
CAUTION
During acceleration/deceleration, the running frequency within the set area is valid.
REMARKS
Write inhibit error " " occurs if the frequency jump setting ranges overlap.
