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.
The value set to 1A, 2A or 3A
is a jump point and operation
is performed at this frequency.

31 Frequency jump 1A --- 0 to 120Hz,---
• - - -: Function invalid
•Setting is enabled when Pr.
30 = "1"
32 Frequency jump 1B --- 0 to 120Hz,---
33 Frequency jump 2A --- 0 to 120Hz,---
34 Frequency jump 2B --- 0 to 120Hz,---
35 Frequency jump 3A --- 0 to 120Hz,---
36 Frequency jump 3B --- 0 to 120Hz,---
•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.
•To jump to 35Hz between 30 and 35Hz, set 35Hz in
Pr. 33 and 30Hz in Pr. 34.
CAUTION
During acceleration/deceleration, the running frequency within the set area is
valid.
REMARKS
Write disable error " " occurs if the frequency jump setting ranges overlap.
