Abstract: Aiming at the shortcomings of the traditional field bus technology in industrial motion control systems, such as poor realtime performance and small capacity, the characteristics of the motion control system are studied and EtherCAT communication technology is introduced into industrial motion control systems. The hardware of the EtherCAT slave motion controller is developed using STM32F427 master controller chip, AX58100 slave controller and JY02 motor driver chip. The experimental results show that the developed slave control system is fully compatible with the master TwinCAT 3 communication, and the communication speed and reliability are greatly improved compared with the traditional bus communication technology, which can better meet the development needs of intelligent and flexible production.
