Design of Motor Drive Module on CAN Bus

Abstract

Considering the limited function of RS-232 and RS-485 bus in communication, the motor drive module (MDM) uses CAN bus as a means of communication. The motor drive module (MDM) uses single-chip AT90CAN128 as main controller to control the velocity and position of drive mechanism. It combines input and display module and actuator through single-chip AT90CAN128 and CAN bus communications technology, which realize a multi-host of the real-time communication among modules. The motor drive module (MDM) based on CAN bus will be more efficient in communication, system expanding and better value.
