Modbus RS485 Closed Loop Stepper Motor Driver 2.1-8.0A 30-110VDC or 18-80VAC

CLRS Series are closed loop stepper driver based on standard Modbus RS485 protocol, using RS485 communication can network up to 31 axes, built-in PR feature with 16-segment position table(PR Mode). They can not only solve the problem of step loss in the open loop stepper system, but also can save additional controllers in most of point-to-point applications, to greatly enhance system reliability and reduce the cost. CLRS Series also support the feature of teaching, the operation modes of Profile Position, Profile Velocity and Homing.
