CU320-2 DP Control Unit Siemens

Обзор



The communication, open-loop and closed-loop control functions for one or more Line Modules and/or Motor Modules are executed in the CU320-2 DP Control Unit. It communicates with the higher-level control via PROFIBUS DP.

Дизайн



The CU320-2 DP Control Unit has the following interfaces as standard:

• 4 x DRIVE-CLiQ sockets for communication with other DRIVE-CLiQ nodes, e.g. Motor Modules, Active Line Modules, Sensor Modules, Terminal Modules

• 1 PROFIBUS interface with PROFIdrive profile

• 12 parameterizable digital inputs (isolated)

• 8 parameterizable bidirectional digital inputs/digital outputs (non-floating)

• 1 serial RS232 interface (e.g. to connect the AOP30 Advanced Operator Panel)

• 1 interface for the BOP20 Basic Operator Panel

• 1 slot for the CompactFlash card on which firmware and parameters are stored

• 1 slot for mounting an option module (e.g. TB30 Terminal Board)

• 2 rotary coding switches for manually setting the PROFIBUS address

• 1 Ethernet interface for commissioning and diagnostics

• 3 test sockets and one reference ground for commissioning support

• 1 connection for the electronics power supply via the 24 V DC supply connector

• 1 PE/protective conductor connection

• 1 ground connection

A shield connection for the signal cable shield on the option module is located on the CU320-2 DP Control Unit.

The available option slot is used to expand the interfaces, e.g. terminals or communication.

The status of the CU320-2 DP Control Unit is indicated via multicolor LEDs.

As the firmware and parameter settings are stored on a plug-in CompactFlash card, the Control Unit can be changed without the need for software tools.

The CU320-2 DP Control Unit can be mounted on the side of the Line Module via brackets integrated in a Line Module. The CU320-2 DP Control Unit can also be fixed to the wall of the control cabinet using the integrated fixing lugs.

Интеграция



DRIVE-CLiQ components such as Motor Modules and Active Line Modules can be connected to a CU320-2 DP Control Unit. The number of modules depends on the performance required, including duty type and additional functions.

The CU320-2 DP Control Unit and other connected components are commissioned and diagnosed using the STARTER commissioning tool from Version 4.1 SP5 and the installed SINAMICS Support Package SSP_SINAMICS_V4_3_2 or the AOP30 Advanced Operator Panel.

The BOP20 Basic Operator Panel can also be snapped onto the CU320-2 DP Control Unit during operation for troubleshooting.

The CU320-2 DP Control Unit requires a CompactFlash card with firmware version 4.3 or higher.
