SINAMICS S120 drive system
Control Units
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. A PROFINET (PN)
variant and a PROFIBUS (DP) variant are available for fieldbus
communication.
CompactFlash card for CU310-2 Control Units
The CompactFlash card contains the firmware and set parame-
ters. The CompactFlash card is plugged into the appropriate 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 con-
tains licensing codes which are required to enable firmware
options.
Currently, the following firmware options can be ordered in
addition to the article number:
•
Safety Integrated Extended Functions, order code
F01
•
High output frequency
1)
, order code
J01
The firmware options can also be enabled on-site, for example,
if the Safety Integrated Extended functions are to 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
cannot be transferred to other CompactFlash cards.

Design
CU310-2 Control Units feature 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 encoders without incremental signals
•
1 PE connection
•
1 connection for the electronics power supply via the 24 V DC
supply connector
•
1 temperature sensor input (KTY84-130/PT1000 or PTC)
•
3 parameterizable, fail-safe digital inputs (floating) (can be
used with firmware version V4.5 or higher) or alternatively
6 parameterizable digital inputs (floating).
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 (floating)
•
1 parameterizable, fail-safe digital output (floating) (can be
used with firmware V4.5 or higher) 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
diagnostics
•
1 slot for the CompactFlash card on which firmware and
parameters are stored
•
1 PM-IF interface for communication with the Power Modules
in blocksize format
•
3 measuring sockets and one reference ground for
commissioning support
•
1 interface to the BOP20 Basic Operator Panel
3)
The status of the CU310-2 Control Unit is indicated via
multi-color LEDs.
A BOP20 Basic Operator Panel can also be snapped directly
onto the CU310-2 Control Unit for diagnostic procedures.
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, an external 24 V power supply must be
connected to terminal X124.

BOP20 is not used on machine tools.
