6.3.2 Avoid mechanical resonance points (frequency jumps) (Pr. 31 to Pr. 36)
When it is desired to avoid resonance attributable to the natural frequency of a mechanical sys-
tem, these parameters allow resonant frequencies to be jumped.
The above parameters can be set when Pr. 160 = 0.
Up to three areas may be set, with the jump frequencies set to either the top or bottom point of
each area.
The settings of frequency jumps 1A, 2A, 3A are jump points, and operation is performed at these
frequencies in the jump areas.
