6.2.6 frequency jump
In systems with mechanical resonances, you can skip this frequency range
for stationary operation.

The skip frequency function is used to prevent the frequency inverter
from being run at a specific output frequency, e.g. at a frequency that
will cause mechanical resonance in a specific machine.
Parameter P-27 is used to define the center of the skip frequency band
and is used together with parameter P-26. The output frequency will
run through the specified band at the speeds set in P-03 or P-04 without
holding an output frequency that falls within the defined band.
If the frequency reference value applied to the frequency inverter falls
within the band, the output frequency will remain at the upper or lower
limit of the band.
