Communication Design of CAN Bus and AC Servo System Based on DSP

Cheng Shan-mei

Abstract

The characteristics of CAN bus and CAN controller of TMS320LF2407A are proposed in this paper.AC servosystem is connected with CAN bus by PCA82C250 and communicated with host computer by CAN card.The hardware interface circuit is presented,and the designs of system software and CAN communication software are analyzed respectively.Experimental results show that single servo controller can be connected with CAN bus as an intelligent node in a control network.
