Three-phase servo-drive CWDS556

three-phase stepper20-54 Vcompact

Overview
The CWDS556 is a 3-phase closed-loop stepper servo driver delivering up to 5.6A at 20–50V DC. It combines 3-phase closed-loop control with DSP plus vector control to provide smooth motion, high positioning reliability and avoidance of missed steps in industrial motion applications. The unit is compact (118 x 75 x 34 mm) for easy integration into machine control enclosures.
