4.2.16 Frequency jump (Pr. 31 to Pr. 36)
Pr. 31 "frequency jump 1A"
Pr. 32 "frequency jump 1B"
Pr. 33 "frequency jump 2A"
Pr. 34 "frequency jump 2B"
Pr. 35 "frequency jump 3A"
Pr. 36 "frequency jump 3B"
#
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
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
Note: 1. During acceleration/deceleration, the running frequency within the set area is valid.
