5.1.11

Suppression of resonant frequencies

P25 (A-0-0025)
P26 (A-0-0026)
Example:
Resonant frequencies
occur in the 60–65 Hz
range.
Setting:
1. P25 = Er1
2. P26 = 62.5 Hz
3. P27 = 2.5 Hz
P27 (A-0-0027)
P28 (A-0-0028)
P29 (A-0-0029)
P30 (A-0-0030)
P31 (A-0-0031)
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 and f=0 limit values are used by the drive even if they are
max
within the suppressed range.
