8.3.2 Skip frequencies
By means of the three parameterisable skip frequencies, crical frequencies can be sup-
pressed which lead to mechanical resonances in the system.
Details
A blocking zone is acve as soon as the frequency for this blocking zone is set to value unequal
to "0 Hz".
•
The set frequency denes the centre of the range to be masked out.
①
•
The set bandwidth denes its total size.

Example: For a blocking zone, the frequency is set to 20 Hz and the bandwidth to 10 Hz.
These sengs mask out the range from 15 Hz to 25 Hz.
Notes:
•
Skip frequencies are absolute values. With the seng "20 Hz", at the same me also the
skip frequency "-20 Hz" is dened.
•
The inverter accelerates/decelerates the motor by the range to be masked out. A connu-
ous operaon within this range is not possible.
•
A blocking zone is not acve if its bandwidth is set to "0 Hz".
Adjacent and overlapping ranges:
•
Example on the le: If the ranges are closely spaced, the ranges are passed through as
shown.
•
Example on the right: If the ranges overlap, the lowest and highest value form a new
range. In the status display 0x291F:016, both ranges are shown as acve.
