Siemens Sinamics S220 drive system

Siemens has launched the Sinamics S220 high-performance drive system. The CU320-3 control unit gives the ability to operate up to 12 axes, achieving good integration density. The built-in multicore processor provides the necessary computing power, while the Drive-Cliq-Express interface, with a speed of 1 Gbps, allows for rapid data transfer.

The system has also been designed to meet the demands of digital transformation. High-frequency data transmission for predictive maintenance occurs via the X128 interface, and integration into Siemens’ TIA Portal, as well as virtual commissioning with DriveSim Designer, improves the engineering workflow. 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 Wi-Fi adapter enables flexible remote access.

The drive system offers a broad performance range. Air-cooled motor modules in book-size and chassis designs, with a voltage range of 380–480 V, are available. The rated current ranges from 3 A (1.1 kW) to 1518 A (900 kW) and can be expanded up to 6984 kW through an eightfold parallel connection. For power supply, regenerative active in-feeds ranging from 210 to 921 kW are available, also scalable through parallel connection.

With software version 6.6, the safety architecture reduces the safety cycle from 12 to 4 ms, enabling faster reactions and higher productivity. The drive is SIL 3 certified for all operating states and offers the certified level of safety in critical applications.
