Control signal filter / filter of actual acceleration value

The filters in the Compax3 firmwar are implemented as P-T1 filters (first order de-
lay component see chapter 0)
The two "control signal filter (velocity loop)" (Object 2100.20) and "acceleration
value filter" (Object 2100.21) are set in µs. The value range for these filters is 63...
8 300 000µs. Depending on the replacement time consant of the closed velocity
loop, we can make recommendations for the setting.
Setting recommendation for "control signal filter (velocity loop)":
O2100.20 = O2210.17[µs] / 5
O2100.20 = O2210.17[µs] / 3 - 1333µs
O2210.20 = 0
O2210.17: Object recplacement time constant of the velocity loop in µs.
O2100.20: Object control signal filter (velocity loop) in µs.
It cannot be excluded that the filter may have a destabilizing effect even though set
according to the above recommendation. In this case the filter time constant must
be reduced.
