7.3.2. Skip frequencies
By means of the three parameterisable skip frequencies, critical frequencies can be
suppressed which lead to mechanical resonances in the system.
Details
A blocking zone is active as soon as the frequency for this blocking zone is set to value
unequal to "0 Hz".
• The set frequency defines the centre of the range to be masked out.
①
• The set bandwidth defines its total size.
②
Example: For a blocking zone, the frequency is set to 20 Hz and the bandwidth to 10 Hz.
These settings mask out the range from 15 Hz to 25 Hz.
Notes:
• Skip frequencies are absolute values. With the setting "20 Hz", at the same time also
the skip frequency "-20 Hz" is defined.
• The inverter accelerates/decelerates the motor by the range to be masked out. A
continuous operation within this range is not possible.
• A blocking zone is not active if its bandwidth is set to "0 Hz".
Adjacent and overlapping ranges:
• Example on the left: 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 active.
