Filter for the acceleration feedforward
This filter filters the acceleration feedforward. With this filter at oscillatory systems the
feedforward can be adapted, so that the system shows the requested behavior. The set-
tings of the filter are made via the parameters

. The calculation of the
filter constants are made via the command 2 of parameter

Filter for speed set value
The speed set value can be filtered via a PT
1
filter as well as via a biquad filter. The bi-
quad filter can be used if a specified resonance frequency is not supposed to be excited.
A plain smoothing (

) can be used at the acceleration feedforward via the entire
speed set value (
Z

, bit 1), which should approximately accord to the additional time
constant of the speed closed loop.
The calculation of the filter constants of the biquad filter is made via the command 3 of
the parameter

. The filter is activated via the bit 20 of

, otherwise the PT
1
element is effective.
