PMC007BxSxP is a kind of miniature integrated stepper motor microstepping controller, which can be directly installed in the rear of 42/57/86 series stepper motor. The series controller provides a variety of models which can be chosen based on bus control of modbus-RTU and different current value. It is easy to achieve industrial control network of as many as 120 nodes, which can achieve closed-loop control based on encoder according to the requirements of user. PMC007BxSxP adopts industrial standard modbus-RTU control protocol, which not only greatly simplifies the complexity of the upper layer control system, but also maximally reserves flexibility of control, and is suitable for all kinds of high precision, wide range of industry using.
