Abstract: Aiming at the problem of the normal testing and running of motor control system was affected by monitoring the multichannel internal operation datum of system, a new scheme was put forward, where main controller of PWM induction motor control system TMS320F28069 and auxiliary controller TMS320F2812 were cooperated. The hardware and software of communication system of tested datum on CAN bus were designed by eCAN modules of main and auxiliary controllers. The waveforms of multichannel variables were monitored and shown in real time with graph function of TI integrated design tools CCS3.3. The experimental results indicate that the communication system of tested datum peculiarity such as strong antiinterference ability, good realtime, high accuracy, simpleness, reliability, no effect to main control program, and so on.
Key words: CAN bus; test data; communication system
