Sinamics CU250S-2 control units complement Sinamics G120 variable-speed drives, and are especially suited to high-speed applications. The units have voltage and current control modes, along with sensorless vector control, closed-loop vector control via speed encoder, and position control via positional encoder. The units use a 1x integrated PID controller and feature a motor holding brake.
Targeting applications with numerous inputs and outputs, the Sinamics CU250S-2 units feature eleven 24-V digital inputs, two analog inputs, four selectable direct input/direct output, and three fail-safe direct inputs. They integrate STO (Safe Torque Off), SBC (Safe Brake Control), and SS1 (Safe Stop 1) features to suit safety requirements.
