P-0-1122, Velocity control loop filter: bandwidth of band-
stop filter
Input min/max: Default value: Unit:
MPB: 10,0 / 1000,0 --- Hz
This parameter is used to parameterize the bandwidth of the 4 band-stop
filters that can be selectively activated via P-0-1120 [n] = 2. The input
value is in Hz, i.e. the actual frequency (f=1/T) is input. Notes on how to
parameterize the band-stop filter are contained in the Functional
Description.

P-0-1123, Vel. cont. loop filter: center frequency of band-
stop filter
Input min/max: Default value: Unit:
MPB: 4,0 / 4000,0 --- Hz
This parameter is used to parameterize the center frequency of the 4
band-stop filters that can be selectively activated via P-0-1120 [n] = 2. The
input value is in Hz, i.e. the actual frequency (f=1/T) is input. Notes on
how to parameterize the band-stop filter are contained in the Functional
Description.

P-0-1125, Velocity control loop: average value filter clock
Input min/max: Default value: Unit:
MPB: 1 / 16 1 --
This parameter allows filtering the velocity control loop deviation with a
moving average filter. In the case of this filter type and with constant input
value, the output is always:
M
X
Y =∆
This means that the filter output, with constant input value, increases in a
linear way and has reached its final value at the filter output after the time
tMT
A
=⋅.
Note: This filter type therefore does not show the typical "creep
behavior" (filter output increases and decreases according to
an e-function!) of the usual VZ1 and VZ2 filters.
