When it is desired to avoid resonance attributable
to the natural frequency of a mechanical system,
these parameters allow resonance occurrence
speeds to be jumped. Up to three areas may be
set, with the jump speeds 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 speed.

• To fix the speed at 600r/min between Pr. 33 and Pr. 34 (600r/min
and 700r/min), set 600r/min in Pr. 33 and 700r/min in Pr. 34.
• To jump to 700r/min between 600r/min and 700r/min, set 700r/
min in Pr. 33 and 600r/min in Pr. 34.
CAUTION
During acceleration/deceleration, the running speed within the set area is valid.
REMARKS
If the speed jump setting ranges overlap, a write disable error "
" appears.
The units of the running speed monitor display of the PU (FR-DU04
-1
/FR-PU04V), the running speed/
frequency setting in the PU operation mode, and the parameter setting unit used for frequency setting can be
changed from the frequency to the motor speed or machine speed.
