Benefits
•
Modularity ensures flexibility for a drive concept that is fit for
the future
- Control Unit can be hot-swapped
- Pluggable terminals
- The modules can be easily replaced, which makes the
system extremely service friendly
•
The integrated safety functions significantly reduce the costs
when integrating drives into safety-oriented machines or
systems
•
Communications-capable via PROFINET or PROFIBUS with
PROFIdrive Profile 4.0
- Plant-wide engineering
- Easy to handle
•
The innovative circuit design (bidirectional input rectifier with
"pared-down" DC link) allows the kinetic energy of a load to be
fed back into the supply system when PM250 Power Modules
are used. This feedback capability provides enormous poten-
tial for savings because generated energy no longer has to be
converted into heat in a braking resistor
•
Integrated USB interface for simplified, local commissioning
and diagnostics
•
Application-specific functions for pumps, fans and
compressors
Integrated are, e.g.:
- 4 freely-programmable PID controllers
- Application-specific wizards
- Pt1000/LG-Ni1000 temperature sensor interface
- 230 V AC relay
- 3 freely-programmable digital time switches
•
New with CU250S-2 Control Units: Integrated positioning
functionality (basic positioner EPos) supports process-related
implementation of positioning tasks with a high dynamic re-
sponse. Positioning can be implemented with an incremental
and/or absolute encoder (SSI)
•
New with CU250S-2 Control Units: Encoder interfaces
Drive-CLiQ, HTL/TTL/SSI (SUB-D) and Resolver/HTL (termi-
nal)
•
New with CU250S-2 Control Units: Vector control with or
without sensors
•
Integrated control functionality by using BICO technology
•
An innovative cooling concept and coated electronic modules
increase robustness and service life
- External heat sink
- Electronic components are not located in air duct
- Control Unit that is completely cooled by convection
- Additional coating of the most important components
•
Simple unit replacement and quick copying of parameters
using an optional Operator Panel or an optional memory card
•
Quiet motor operation as a result of the high pulse frequency
•
Compact, space-saving design
•
Software parameters for simple adaptation to 50 Hz or 60 Hz
motors (IEC or NEMA motors)
•
2/3-wire control for static/pulsed signals for universal control
via digital inputs
•
Fast engineering and commissioning by using standard
engineering tools such as SIZER for Siemens Drives,
STARTER and Drive ES – STARTER is integrated into STEP 7
using Drive ES Basic, with all of the benefits of central data
management and totally integrated communication
•
Certified worldwide for compliance with CE, UL, cUL, C-Tick
and Safety Integrated according to IEC 61508 SIL 2 and
EN ISO 13849-1 PL d and Category 3

Design
Application-orientated design of SINAMICS G120
SINAMICS G120 standard inverters are modular inverters for
standard drives. Selection of the SINAMICS G120 is reduced to
two or three steps thanks to the modular system used.
Selecting the Control Unit
The optimum Control Unit is selected first, based on the number
of I/Os and any additional functions required such as Safety
Integrated or HVAC. The communication options are already
integrated and do not have to be additionally ordered or plugged
in. Three product series are available corresponding to the partic-
ular application.
CU230P-2 Control Units
The CU230P-2 Control Units have been specifically designed for
pump, fan and compressor applications.
The CU230P-2 is the Control Unit for SINAMICS G120P and
SINAMICS G120P Cabinet for pumps, fans and compressors.
Detailed information can be found in Catalog D 35.
CU240B-2 and CU240E-2 Control Units
The CU240B-2 and CU240E-2 Control Units are suitable for a
wide range of applications in general machine construction,
such as conveyor belts, mixers and extruders.
CU250S-2 Control Units
The CU250S-2 Control Units are suitable for applications invol-
ving single drives with exacting speed control requirements
such as extruders and centrifuges, and for positioning tasks
such as conveyor belts, lifting/lowering devices, etc. They can
also be used to implement multi-motor drives without DC cou-
pling such as wire-drawing machines and simple material lines.
