Example:
Resonant frequencies
occur in the 60–65 Hz
range.
Setting:
1. P25 = Er1
2. P26 = 62.5 Hz
3. P27 = 2.5 Hz

Suppression of resonant frequencies
The suppression of resonant frequencies serves to suppress mechanical
resonant sounds of the machine and thus to achieve smooth machine
operation.
A maximum of 3 frequency ranges can be suppressed. The center
frequencies and bandwidths of the desired ranges must be entered in order
to be able to pass these ranges as fast as possible using the selected
acceleration and braking ramps.
.
The f
max
and f=0 limit values are used by the drive even if they are
within the suppressed range.
