Siemens Launches New SINAMICS S220 Drive System

2025-11-12

Siemens has officially launched the new SINAMICS S220 drive system, setting a new benchmark for industrial drive technology. As an upgrade to the SINAMICS S120, the S220 features the new CU320-3 control unit and version 6.6 software, achieving a significant performance leap. This system is a key component of Siemens' Xcelerator portfolio, seamlessly integrating into digital workflows to help companies improve productivity, optimize engineering processes, and enhance system reliability.

Core Technology: CU320-3 Multi-Axis Control Unit

At the heart of the S220 is the new CU320-3 control unit, whose unique architecture supports single-machine control of up to 12 axes, boasting industry-leading integration density. A built-in multi-core processor provides powerful computing capabilities, while the Drive-Cliq-Express interface ensures smooth data transmission at 1GBit/s high speed. Innovative pulse sequence technology achieves sensorless control through three voltage sensors per axis, achieving near-encoder accuracy while improving energy efficiency and system stability.

Intelligent Drives for Digitalization

The S220 supports high-quality field data acquisition, providing a foundation for Industry 4.0 and new business models. The X128 interface enables high-frequency data transmission, supporting predictive maintenance and intelligent optimization. The system can be integrated into the TIA Portal platform and used with DriveSim Designer for virtual commissioning, significantly optimizing engineering processes. The intelligent drive interface is available in a compact panel (SDI S220) or a remote version (SDI Pro), with an optional WiFi adapter for flexible remote access, convenient and efficient operation.

Modular and Flexible Performance

The S220 motor modules are available in book-sized and rack-mount options, with a voltage range of 380–480V and rated current from 3A (1.1kW) to 1,518A (900kW). It can be expanded to 6.984MW through eight-way parallel connection, with a module overload capacity of 300%. Regenerative active power modules range from 210–921kW and also support parallel expansion. The air-cooled universal module can be flexibly used as a motor or power supply module, covering full functionality and performance requirements with only six devices, enabling rapid response to diverse industrial applications.

Safety and Cybersecurity Assurance

The S220 is equipped with version 6.6 software, reducing the security cycle from 12 milliseconds to 4 milliseconds, achieving faster response and higher productivity. Automated background testing ensures continuous operation, and offline parameterizable security functions simplify engineering implementation. The system is SIL 3 certified for all operating states, complies with the IEC 62443-4-1 standard, and is independently certified by TÜV SÜD. Built-in security functions such as access control, data encryption, and firmware integrity checks effectively enhance network protection capabilities.

Sustainability and Green Design

The S220 balances performance and environmental protection. Its compact design saves installation space, uses energy-saving and recyclable materials, and its high repairability reduces its carbon footprint. The Industrial Edge application can collect and visualize energy consumption and CO₂ emissions in real time, and the ISO 14021 certified Environmental Product Declaration (EPD) records the entire lifecycle performance, reflecting Siemens' commitment to green industry and sustainable development.

High-Efficiency Integration and Application Value

Enterprises can choose the CU320-3 and motor/power supply modules according to their needs, perform virtual commissioning through TIA Portal and DriveSim Designer, and achieve predictive maintenance through the X128 interface and Industrial Edge. The choice of compact or remote SDI interface makes operation more efficient and convenient. The S220 not only improves production efficiency and system integration, but also ensures the safety and stability of critical applications, providing reliable support for smart manufacturing and digital transformation.

Summary

The SINAMICS S220 drive system integrates high performance, multi-axis control, digital integration, safety, and sustainable design, providing industrial enterprises with a future-oriented drive solution. It significantly improves production efficiency, system integration, and operational safety, while supporting predictive maintenance and rapid response to production needs. Its compact design and application of environmentally friendly materials reflect Siemens' commitment to green industry, laying a solid foundation for smart factories and digital production.
