SINAMICS S120 CU320-2 Control Unit

SINAMICS S120 CU320-2 control unit

Each SINAMICS S120 CU320-2 control unit manages up to six high-performance servo or vector axes.  For standard applications, up to 12 V/Hz axes can be operated from one CU320-2. The enhanced processor enables increased functionality for positioning, safety integrated functions and drive control charts to be handled by one control unit, thus significantly reducing drive system costs.

This second-generation SINAMICS control unit also provides an Ethernet programming port, more I/O and controller-to-controller communication.

With the goal of delivering more functionality more economically, the SINAMICS S120 CU320-2 also cuts costs for users through simplified performance licensing, fewer hardware requirements and smaller cabinet space requirements.
