Parameter Description
P254* At filter characteristic 1 (P256=1):
Filter Frequency Resonant frequency of the band-stop filter.
254 Harmonics of exactly this frequency are completely
eliminated by the band-stop filter.
The extent to which neighbouring frequencies are
weakened depends on the quality/selectivity of band-stop
filter P253.
At filter characteristic 2 (P256=2):
Key frequency (-3dB) of the low-pass filter. At this
frequency the amplitude is weakened to 70% (=3dB).
r255 Visualization parameter for displaying the torque setpoint
Torq(set,n-Reg) at the output of the speed controller.
255
P256* The parameter defines the filter characteristic.
Filter Character
Value = 0: Enabled
256 Value = 1: Band-stop
Value = 2: Low pass
Value = 3: extended band-stop
Further values for future use !
P257* Further essential quantities of the filter can be preset via
Filter Adjust1 this parameter depending on the filter characteristic.
257 Filter characteristic 1 (band-stop):
The remaining amplitude at filter frequency can be preset
via this parameter. In view of the phase response, it can
be worthwhile not to suppress this amplitude completely.
Filter characteristic 2 (low-pass):

Without function.

P258* Further essential quantities of the filter can be preset via
Filter Adjust2 this parameter depending on the filter characteristic.
258
P259 Function parameter for entering the dead time for the filter
Tdead RefModel of the reference model. The parameter is only effective if
the structure "PI controller with reference model" has
259 been selected in P238.

P260* BICO parameter for selecting the connector from which
S.Torq (set) the torque setpoint is to be read in during "Master drive"
operating mode.
