CU320-2 Control Unit
■
Design
CU320-2 Control Units feature the following interfaces as
standard:
•
4 DRIVE-CLiQ sockets for communication with other
DRIVE-CLiQ devices, e.g. Motor Modules,
Active Line Modules, Sensor Modules, Terminal Modules
•
CU320-2 PN: 1 PROFINET interface with 2 ports
(RJ45 sockets) with PROFIdrive V4 profile
•
CU320-2 DP: 1 PROFIBUS interface with PROFIdrive V4 pro-
file
•
12 parameterizable digital inputs (floating)
•
8 parameterizable bidirectional digital inputs/digital 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 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
power supply connector
•
1 PE (protective earth) connection
•
1 ground connection
A shield connection for the signal cable shield on the option mo-
dule is located on the CU320-2 Control Unit.
The available option slot is used to expand the interfaces, for
example, to include additional terminals or for communication
purposes.
The status of the CU320-2 Control Unit is indicated via multi-co-
lor 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 Control Unit can be mounted on the side of the
Line Module in booksize format via brackets integrated in a Line
Module. The CU320-2 Control Unit can also be fixed to the wall
of the control cabinet using the integrated fixing lugs. As the
CU320-2 Control Unit is not as deep as the Line Modules, suit-
able spacers are available to increase the depth of the CU320-2
Control Unit to 270 mm (10.6 in).
■
Integration
DRIVE-CLiQ components, for example, Motor Modules and
Active Line Modules, can be connected to a CU320-2 Control
Unit. The number of modules depends on the performance
required, including duty type and additional functions.
The BOP20 Basic Operator Panel can also be snapped onto the
CU320-2 Control Unit during operation to perform troubleshoo-
ting procedures.
The CU320-2 Control Unit and other connected components are
commissioned and diagnosed with the STARTER commissio-
ning tool.
The CU320-2 PN Control Unit requires a CompactFlash card
with firmware V4.4 or higher.
The CU320-2 DP Control Unit requires a CompactFlash card
with firmware V4.3 or higher.
