Additional controls for Active Infeed

Function description
With the "Supplementary closed-loop control" function module, parameterizable band-stop
filters (Page 40) can be used with whose help path resonances can be attenuated.
The main application for these band-stop filters is in weak line supplies in which the resonance
point of the line filter can drop to one quarter of the controller frequency.

To activate the function module, proceed as follows:
1. Select the infeed unit in the project navigator and open the "Properties" shortcut menu.

2. Click the "Function modules" tab.
