Siemens sets new standards in drive technology with Sinamics S220 drive system
Multi-Axis Control Unit CU320-3: The Technological Heart
At the core of Sinamics
S220, the newly developed control unit CU320-3 sets pioneering standards in
drive technology with its unique architecture. With the ability to operate up
to 12 axes on a single control unit, the system achieves an outstanding level
of integration density. The built-in multicore processor provides the necessary
computing power, while the Drive-Cliq-Express interface, with a speed of
1GBit/s, ensures rapid data transfer. An innovative test pulse method using
three voltage sensors per axis enables sensorless control with near-encoder
quality – while also improving energy efficiency and robustness.
Digitalization and Future-Readiness
Sinamics S220 has been
fundamentally reconceived to meet the demands of digital transformation. The
targeted generation of high-quality field data opens up new business models in
Industry 4.0. High-frequency data transmission for predictive maintenance
occurs via the X128 interface. Integration into the TIA Portal, as well as
virtual commissioning with DriveSim Designer, significantly improve the
engineering workflow. New assistants and an undo function facilitate operation.
The Smart Drive Interface is available as a compact panel (SDI S220) directly
on the CU320-3 or as a remote version (SDI Pro with a larger display and web
server). Optionally, a Smart WiFi adapter enables flexible remote access.
Flexibility and scalability
The Sinamics S220 drive
system offers a broad performance spectrum for industrial applications. Upon
market launch, air-cooled motor modules in booksize and chassis designs, with a
voltage range of 3AC 380 to 480 V, are available. The rated current ranges from
3 A (1.1 kW) to 1.518 A (900 kW) and can be expanded up to 6.984 kW through
8-fold parallel connection. For power supply, regenerative active infeeds
ranging from 210 kW to 921 kW are available, also scalable through parallel
connection. Additionally, air-cooled universal modules are introduced, which
can be flexibly operated as motor modules or active line modules. Six devices
cover the entire functional and performance range for spare parts cases and
allow rapid adaptation to changing requirements.
Safety integrated and cybersecurity at the highest level
With software version 6.6,
the Sinamics S220 sets new standards in plant safety. The new safety
architecture reduces the safety cycle from 12 ms to 4 ms, enabling faster
reactions and higher productivity. Automatic background tests ensure
uninterrupted operation, while offline parameterizable safety functions greatly
simplify engineering. The drive is SIL 3 certified for all operating states and
offers the certified level of safety in critical applications. The Sinamics
S220 was developed within a secure development process according to the
standard IEC 62443-4-1, independently certified by TÜV SÜD. The drive system
features numerous integrated safety functions, including user and access
control, encrypted drive data, and integrity and authentication checks for
firmware and configuration data. These features, along with additional measures
within the machine, enhance resilience against cybersecurity risks.
Sustainable Drive System for the Future of Industry
With Sinamics S220, Siemens
presents a drive system that combines sustainability and performance. Its
compact design saves space while resource-saving materials and high
reparability and recyclability contribute to reducing carbon impact. Industrial
Edge applications enable the capture and visualization of energy consumption
and CO₂
emissions. The ISO 14021 certified Environmental Product Declaration (EPD)
documents its environmental performance over the entire lifecycle, underscoring
Siemens’ commitment to sustainable industrial solutions.
