When required, during the basic parameterization you can switch-in various function
modules for the selected infeed unit.
Note
You can only activate and deactivate function modules OFFLINE.
Note
The display of the function modules that can be activated is dynamic and depends on the
selected infeed and the configuration of this infeed.
The following table provides an overview of the function modules that can be used. In
addition to the individual function modules, the table includes an explanations of how each
function module can be used.

4.8 Basic parameterization of the drive objects
Explanation
Redundant operation of several ALMs connected to one DC link.
Control of an external Braking Module in order to be able to absorb
braking energy in the event of a power failure.
Activates the F blocks.
For applications with asymmetrical line voltages: A negative se-
quence system current controller is used to balance the line cur-
rents and reduce the DC link ripple.
For applications with resonance effects in the current or the filter
voltage (e.g. in line systems with low short-circuit power ratings).
Freely parameterizable band-pass filters for resonance damping.
For power generation applications in power grids: Functions for grid
support with fault ride-through and line monitoring (incl. active anti-
islanding) according to the applicable grid codes.
Installation, synchronization and operation of island grids: Control of
line frequency and line voltage in single operation or together with
other generators.
Function to record hardware-related fault events
For power generation applications: Magnetization of a transformer
to limit the inrush current when the line system is connected. Com-
pensation of direct current components and voltage drops at the
transformer in conjunction with dynamic grid support or grid droop
control.
Precise cos(Phi) determination based on fundamental current and
voltage components with BICO-interconnectable input variables (in
contrast to power factor r0038).
