4.7 Basic parameterization of the drive objects
The function modules that can be used are presorted in two areas:
● Frequently used function modules
– Master/slave
– External Braking Module
● Additional function modules
– Fault ride-through
– Line droop control; installation, synchronization and operation of stand-alone systems:
– Line transformer
– Recorder
– Cosine Phi add-on module
– Additional control
Activating function modules
1. Activate the required function module by clicking the option.
Repeat this for all additional function modules that you wish to activate.
2. Save the project to backup the settings.

Redundant operation of several ALMs on one DC link.
Control of an external Braking Module in order to be able to collect braking energy in
the event of a power failure.
For power generation applications in an interconnected system: Functions for fault
ride-through and line monitoring (incl. active anti-islanding) according to power system
guidelines.
Control of line frequency and line voltage in single operation or together with other
generators.
For power generation applications: Magnetization of a transformer to limit the inrush
current when the line system is connected.
Compensation for direct current components and voltage drops on the transformer in
conjunction with fault ride-through or line droop control.
Recording fault events
Precise cos(Phi) determination based on fundamental current and voltage
components with BICO-connectable input variables (in contrast to power factor r0038).
For applications with asymmetrical line voltages: A negative sequence system current
controller is used to balance the line currents and reduce the DC-link ripple.
For applications with resonance effects in the current or the filter voltage (e.g. in
systems with low short-circuit power rating): Freely parameterizable band-pass filters
for resonance damping
