Thông tin chi tiết nhất về Biến tần SINAMICS G130 Drive converter chassis units > Control Unit and Control Unit Kit CU320-2 của SIEMENS

Là một thành phần độc lập của 2 modules  cấu thành nên SINAMICS G130 Drive converter chassis units. Bộ converter này cung cấp một bộ điều khiển drive phù hợp cho các nhà chết tạo máy và các nhà thầu nhà máy với các ứng dụng đa dạng. Module này có thể được chứa trong một khoản trống của Power module.

The communication, open-loop and closed-loop control functions for the Power Modules are executed in a CU320‑2 Control Unit.

Communication with the higher-level control system is performed via PROFIBUS DP or PROFINET.

The CU320‑2 Control Unit and the associated CompactFlash card can be ordered separately or as Control Unit Kit. The Control Unit Kit comprises the CU320‑2 Control Unit, a CompactFlash card and the stored drive software.

Design

The CU320‑2 Control Unit features the following connections and interfaces as standard:
- Fieldbus interface:
  +CU320‑2 PN: 1 PROFINET interface with 2 ports (RJ45 sockets) with PROFIdrive V4 profile
  + CU320‑2 DP: 1 PROFIBUS interface with PROFIdrive V4 profile
- 4 DRIVE-CLiQ sockets for communication with other DRIVE-CLiQ devices, e.g. Power Modules, Terminal Modules
- 12 parameterizable digital inputs (floating)
- 8 parameterizable bidirectional digital inputs/outputs (non-floating)
- 1 serial RS232 interface
- 1 interface for the BOP20 Basic Operator Panel
- 1 slot for the CompactFlash card on which firmware and parameters are stored
- 1 slot to install an option module for the interface expansion
- 2 rotary coding switches for manually setting the PROFIBUS address
- 1 Ethernet interface for commissioning and diagnostics
- 3 measuring sockets and one reference ground for commissioning support
- 1 connection for the electronics power supply via the 24 V DC supply connector
- 1 PE connection
- 1 ground connection

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

The available option slot is used to expand the interfaces, e.g. number of terminals.

The status of the CU320‑2 Control Unit is indicated via multi-color LEDs.

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

Integration

Communication between a CU320‑2 Control Unit and the connected components takes place via DRIVE-CLiQ.

A DRIVE-CLiQ cable for connecting the CU320‑2 to the SINAMICS G130 converter is included in the scope of delivery of the Power Module.

The BOP20 Basic Operator Panel can also be snapped onto the CU320‑2 Control Unit during operation for diagnostic purposes.

The CU320‑2 Control Unit and other connected components are commissioned and diagnosed with the STARTER commissioning tool and the installed SINAMICS Support Package.

The CU320‑2 PN Control Unit requires a CompactFlash card with firmware as of V4.4.
The CU320‑2 DP Control Unit requires a CompactFlash card with firmware as of V4.3.
