Study on the Multi-Axis Motion System Based on EtherCAT
To obtain a faster response speed and higher synchronization accuracy, the paper firstly discusses the difficulties and disadvantages of organizing servo motion network with traditional fieldbus. Then, a novel method for constructing multi-axis motion system based on EtherCAT is presented. With DSP and an improved PID control algorithm, the hardware and software design is introduced in details. The system has realized high-speed remote data transmission and high-precision velocity control for Multi-axis which the traditional fieldbus can’t achieve.
