Active Line Modules Siemens

Обзор

The self-commutated infeed/regenerative feedback units (with IGBTs in infeed and regenerative feedback directions) generate a regulated DC link voltage. This means that the connected Motor Modules are decoupled from the line voltage. Line voltage fluctuations within the permissible supply tolerances have no effect on the motor voltage.

If required, the Active Line Modules can also provide reactive power compensation.

Active Line Modules are designed for connection to grounded TN/TT and non-grounded IT supply systems.

Liquid-cooled Active Line Modules are especially suitable for applications where installation space is restricted and for critical environmental conditions.

Active Line Modules are always operated together with the associated Active Interface Modules. These include the necessary pre-charging circuit as well as a Clean Power Filter.

System components such as line reactors, Active Interface Modules, motor reactors and motor filters are air-cooled.

Дизайн

The liquid-cooled Active Line Modules have the following interfaces as standard:

• 1 line supply connection
• 1 connection for the 24 V DC electronics power supply
• 1 DC link connection (DCP, DCN) for supplying the connected Motor Modules
• 3 DRIVE-CLiQ sockets
• 1 temperature sensor input (KTY84-130, PTC or Pt100)
• 1 PE/protective conductor connection
• 2 coolant connections

The following are included in the scope of supply of the Active Line Modules:

• 1 DRIVE-CLiQ cable to connect to the CU320-2 or SIMOTION D4x5 Control Unit
• 1 CD-ROM with Manual in PDF format
• 2 seals for coolant connections

Интеграция

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 precharging 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.
