Integration
Active Line Modules are always operated together with the
associated Active Interface Modules. Active Interface Modules
contain a Clean Power Filter with basic RI suppression, the pre-
charging circuit for the Active Line Module, line supply voltage
sensing circuit and monitoring sensors.
The liquid-cooled Active Line Modules communicate with the
higher-level control module via DRIVE-CLiQ. The control module
in this case can be a CU320-2 or a SIMOTION D Control Unit. An
external 24 V DC power supply is required to operate the Active
Line Modules.

DC link voltage, approx.
The DC link voltage is regulated and can be adjusted as a voltage decoupled from the line voltage.
Factory setting of the DC link voltage: 1.5 × line voltage
