!
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.

!
To fix the frequency at 30Hz between Pr. 33 and
Pr. 34 (30Hz and 35Hz), set 35Hz in Pr. 34 and
30Hz in Pr. 33.
!
To jump to 35Hz between 30 and 35Hz, set 35Hz in
Pr. 33 and 30Hz in Pr. 34.
Note: During acceleration/deceleration, the running frequency within the set area is
valid.
