Based on dsPIC30F6010A which was specifically designed for the digital motor control,the digital DC-motor control system which adopting H-mode bipolar reversible PWM speed-governing method was devel-oped to drive a DC brush motor and to digitalize double closed-loop speed regulation as well as to realize RS-485 communication between micro-processor and touch panel which supporting Modbus protocol.The experi-mental results indicate that excellent speed-adjusting performance and friendly operation interface can be a-chieved in this system,and the system’s simple circuit structure and high reliability can bring about a favora-ble effect in wire-feeding control device.
