SINAMICS S110 servo drives
0.12 kW to 90 kW (0.16 hp to 125 hp)
CU305 Control Unit
■
Overview
CU305 PN Control Unit
The CU305 Control Unit for the communication and open-loop/
closed-loop control functions of a SINAMICS S110 is combined
with the PM340 Power Module to create a powerful single drive.
■
Design
The CU305 Control Unit features the following connections and
interfaces as standard:
•
Fieldbus interface
- CU305 PN: 1 PROFINET interface with 2 ports
(RJ45 sockets) with PROFIdrive V4 profile
- CU305 DP: 1 PROFIBUS interface with PROFIdrive V4
profile
- CU305 CAN: 1 CANopen interface with DS301 V4.0,
DSP402 V2.0, DR303-3 V1.0 profile
•
1 DRIVE-CLiQ socket, used solely to connect a DRIVE-CLiQ
motor or a Sensor Module
•
1 onboard 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 digital inputs (floating), or
alternatively 6 parameterizable digital inputs (floating)
•
5 parameterizable digital inputs (floating)
•
1 parameterizable, fail-safe digital output (floating), or
alternatively 1 digital output (floating)
•
4 parameterizable bidirectional digital inputs/outputs
•
1 analog input ± 10 V, resolution 12 bit + sign
•
1 serial RS232 interface
•
1 slot for the memory card on which the firmware, parameters
and licenses can be stored
•
1 PM-IF interface for communication with PM340 Power
Modules in blocksize format
•
2 test sockets and one reference ground for commissioning
support
•
1 interface to the BOP20 Basic Operator Panel
■
Integration
The CU305 Control Unit controls the PM340 Power Module via
the PM-IF interface.
A BOP20 Basic Operator Panel can also be snapped directly
onto the CU305 for diagnostic purposes. For comprehensive
diagnostics and commissioning functions, an Intelligent Opera-
tor Panel (IOP) can be connected to the RS232 interface.
DRIVE-CLiQ motors can be connected to the integrated
DRIVE-CLiQ socket as well as Sensor Modules (SMC) to permit
the operation of motors without a DRIVE-CLiQ interface.
The status of the CU305 is indicated via multi-color LEDs.
The CU305 can be operated optionally
with a memory card. The
firmware and project data are stored on the plug-in card under-
neath, so that the CU305 can be replaced without the support of
software tools. This memory card can also be used to perform
standard commissioning on multiple drives of identical type. The
card is available as an empty memory card or containing the
latest drive firmware version. The card also contains the safety
license for the Extended Safety Functions. To use these Ex-
tended Safety Functions, a memory card containing the safety
license must be permanently inserted.
The CU305 and other connected components are commis-
sioned and diagnosed with the STARTER commissioning tool.
