Additional controls for Active Infeed
With the "Additional controls" function module, parameterizable bandstop filters (Page 39)
can be used with whose help path resonances can be attenuated.
The main application for these bandstop filters is in weak line supplies in which the
resonance point of the line filter can drop to one quarter of the controller frequency.
Activating the function module
1. Select the infeed in the project navigator and open the "Properties" shortcut menu.
The "Object properties" dialog then opens.
2. Click the "Function modules" tab.
3. Activate the "Additional closed-loop controls" function module in the function modules
selection with a mouse click.
Parameter r0108.03 indicates whether the function module has been activated.
