Based on the high real-time and high reliability of multi-axis synchronous motion technology,this paper addresses the problems of data exchange delay,high fault detection cost,complicated communication network wiring,complex fault diagnosis and failure to locate faults quickly.Designed a control and debugging method for 64-axis synchronous operation multi-axis motion control system based on high-speed D-BUS(Dual-BUS)network,and designed the verification platform.The high-speed D-BUS network consists of a high-speed ReBUS bus of ring Ethernet and an MB+high-speed bus based on RS485.In the field of modern motion control,motion control technology is required not only to have high speed and high precision,but also to improve the linkage accuracy between multiple axes.The networked multi-axis motion control system designed in this paper guarantees high real-time and high reliability of multi-axis synchronous motion.At the same time,the DHMI human-machine interface displays the working status of the system and the specific conditions during the monitoring operation.The hardware and software components are designed according to the motion control system design requirements.The hardware part design mainly includes three parts:logic control module,motion control module and upper computer module during system operation.The software part is designed and implemented by the programmable controller MAC1620 to collect and transmit the control signals during the operation of the system.The servo driver receives the signals and processes them through the output module to the output device.In the aspect of network communication technology,the ReBUS network communication protocol and MB+network fault detection are introduced,including the network communication protocol message structure,address classification,addressing mode,and communication service.The performance of ring Ethernet communication is studied.The mathematical communication model is used to calculate and verify the data communication delay,total frame transmission period and total frame return period.Finally,build a multi-axis motion control system,and the system is continuously debugged and optimized,and its hardware and software functions are tested to meet the design requirements.Based on the networked multi-axis motion control system,the experimental platform is built to test the data transmission between the master and slave stations of the system,measure the communication delay time of the single node of the ring Ethernet,and verify the reliability of the network communication of the 64-axis networked motion control system.
