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.
Function module
Frequently used function modules
Master/slave (r0108.19)
External Braking Module (r0108.26)
Additional function modules
Free function blocks (r0108.18)
Supplementary closed-loop control (r0108.3)
Dynamic grid support (r0108.7)
Grid droop control (r0108.12)
Recorder (r0108.5)
Line transformer (r0108.4)
Supplementary cosinus phi module (r0108.10)
Activating a function module
Proceed as follows to activate a function module:
1. Click on the desired function module (e.g. Master/Slave).
Repeat this step for all additional function modules that you wish to activate.
2. Save the project to back up the settings.

5.7 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 sequence
system current controller is used to balance the line currents and re‐
duce the DC link ripple.
For applications with resonance effects in the current or the filter volt‐
age (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. Compen‐
sation of direct current components and voltage drops at the trans‐
former 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).
