SINAMICS S120 built-in devices
CU310-2 Control Units for single-axis drives
■
Overview
CU310-2 PN and CU310-2 DP Control Units
The CU310-2 Control Unit that is designed for the communica-
tion and open-loop/closed-loop control functions of a
SINAMICS S120 (AC/AC) is combined with the PM340 Power
Module to create a powerful single-axis drive. PROFINET (PN)
and PROFIBUS (DP) variants are available for fieldbus commu-
nication.
CompactFlash Card for CU310-2 Control Units
The CompactFlash card contains the firmware and parameter
settings. The CompactFlash card is plugged into the appropri-
ate slot on the CU310-2
Control Unit.
A CU310-2 Control Unit can perform the communication, open-
loop and closed-loop control functions for one Power Module.
The performance expansion is not required in this case.
In addition to the firmware, the CompactFlash card also contains
licensing codes which are required to enable firmware options.
Currently, the following firmware options can be ordered in addi-
tion to the article number:
•
Safety Integrated Extended Functions, order code
F01
•
High output frequency
1)
, order code
J01
•
DCB Extension, order code
U01
The firmware option can also be enabled on-site, for example,
if the Safety Integrated Extended functions should be enabled
later. You will need the serial number of the CompactFlash card
and the Article No. of the firmware option to be enabled. With this
information, you can purchase the associated license code from
a license database and enable the firmware option. The license
code is only valid for the CompactFlash card declared and can-
not be transferred to other CompactFlash cards.

Design
The CU310-2 Control Unit features the following connections
and interfaces as standard:
•
Fieldbus interface
- CU310-2 PN: 1 PROFINET interface with 2 ports
(RJ45 sockets) with PROFIdrive V4 profile
- CU310-2 DP: 1 PROFIBUS interface with PROFIdrive V4
profile
•
1
DRIVE-CLiQ socket for communication with the DRIVE-CLiQ
motor or other DRIVE-CLiQ devices (e.g. Sensor Modules or
Terminal Modules)
•
1 encoder evaluation for evaluating the following encoder
signals
- Incremental encoder TTL/HTL
- SSI encoder without incremental signals
•
1 PE/protective conductor connection
•
1 connection for the electronics power supply via the 24 V DC
power supply connector
•
1 temperature sensor input (KTY84-130 or PTC)
•
3 parameterizable, fail-safe (can be used with firmware ver-
sion 4.5 and higher) digital inputs (isolated) or alternatively
6 parameterizable digital inputs (isolated).
The fail-safe digital inputs can be routed, i.e. they can be
routed via PROFIsafe to a higher-level controller.
•
5 parameterizable digital inputs (isolated)
•
1 parameterizable, fail-safe (can be used with firmware ver-
sion 4.5 and higher) digital output (floating) or alternatively
1 digital output (floating)
2)
•
8 parameterizable bidirectional digital inputs/outputs (non-
floating)
2)
•
1 analog input, either ± 10 V (resolution 12 bit + sign) or
± 20 mA (11 bit + sign)
•
1 Ethernet interface (socket RJ45) for commissioning and di-
agnostics
•
1 slot for the CompactFlash card on which firmware and para-
meters are stored
•
1 PM-IF interface for communication with the Power Modules
in blocksize format
•
3 test sockets and one reference ground for commissioning
support
•
1 interface to the BOP20 Basic Operator Panel
The status of the CU310-2 Control Unit is indicated via multi-co-
lor LEDs.
A BOP20 Basic Operator Panel can also be snapped directly
onto the CU310-2 Control Unit for diagnostic purposes, for ex-
ample.
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.

In order to use the digital outputs, a 24 V supply voltage must be connec-
ted to terminal X124.
