Siemens Industry is launching a new control unit with positioning capability – enhancing the Sinamics G120 drive system portfolio. The new CU250S-2 adds functional support for vector control with encoder evaluation to the existing standard control units, which already offer comprehensive and integrated safety functions.

This new unit supersedes the CU240S unit within the G120 product portfolio. Single axis applications with induction motors, basic positioning tasks and applications requiring numerous I/Os can now be supported. The new control unit includes safety functions STO (Safe Torque Off), SBC (Safe Brake Control) and SS1 (Safe Stop 1). This allows for applications with basic safety requirements to be catered for. Extended safety functions can be activated via an optional software license.

In line with the modular concept of the Sinamics G120 range, the new control units can be easily combined with all relevant power modules and support all applications currently addressed by the Sinamics G120 portfolio – both with or without encoder evaluation. These include pump, fan and compressor applications, as well as mill, mixer and extruder applications across the automotive, textile, printing, chemical and material handling industrial sectors.
