Overview
CU320-2 PN Control Unit
The communication, open-loop and closed-loop control functions
for one or more Motor Modules and the Line Module are executed
in a CU320-2 Control Unit. The CU320-2 Control Unit is essentially
designed for multi-axis operation.
CU320-2 DP Control Unit with BOP20 Basic Operator Panel
CompactFlash card for CU320-2 Control Units
The CompactFlash card contains the firmware and parameter
settings. The CompactFlash card is plugged into the appropri-
ate slot on the CU320-2 Control Unit.
A CU320-2 Control Unit can perform the communication, open-
loop and closed-loop control functions for several Motor Modules.
The computing capacity required increases in proportion to the
number of connected Motor Modules and system components
and in relation to the dynamic response required. For the CU320-2
Control Unit, the performance expansion is necessary for ma-
chines with 4 axes or more. The utilization of the CU320-2 Control
Unit can be calculated with the SIZER for Siemens Drives
engineering tool.
In addition to the firmware, the CompactFlash Card also con-
tains licensing codes which are required to enable firmware
options.
In addition to the Article No., the following firmware options can
currently be ordered with or without performance expansion:
•
Safety Integrated Extended Functions, order codes per axis
F01 to F06
(see section Safety Integrated)
•
High output frequency

, order code
J01
•
DCB Extension, order code
U01
(further information about
DCB Extension and license upgrades can be found under
Drive Control Chart (DCC) in the section Engineering tools)
After the appropriate license has been purchased via the WEB
License Manager available on the Internet, firmware options can
also be subsequently enabled.

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, 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
profile
•
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 for mounting an option module (e.g. TB30 Terminal
Board)
•
CU320-2
DP: 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 of an option
module is located on the CU320-2 Control Unit.
The available slot is used to optionally 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-
color LEDs.
