Abstract:EtherCAT is becoming more and more widely used in the field of industrial real time Ethernet. Servo system is widely used in factory automation production,CNC machine tools,robot automatic control and other aspects. High-end servo system has some support for real-time Ethernet bus,and the use of EtherCAT for servo system control has a very wide demand. Starting with the introduction of EtherCAT technology and servo control specification,this paper shows how to use Linux operating system to develop and use EtherCAT master station to control servo on embedded platform.
Keywords:EtherCAT;servo system;real-time ethernet technology
