The book \"Principles and Applications of Machine Automation Controllers\" written by Xu Shixu is divided into 8 chapters. First, the working principle of NJ, the hardware unit and system configuration of NJ are introduced. Then the program organization and programming technology of NJ are introduced, and the IEC6113l-3 standard programming language is described in detail with a large amount of space, including tasks, program organization units (programs, function blocks and functions), data types, variables, programming languages (ladder diagrams, structured texts), etc. The instruction system of NJ is introduced, mainly describing the functions and usage methods of common instructions. The use of automation platform software Sysmac Studio is introduced, such as using Sysmac Studio for basic system configuration, EtherCAT network configuration, controller, motion control, cam data, task and data tracking settings; using Sysmac Studio for programming and debugging. The book focuses on the EtherCAT communication, motion control principle, motion control instructions and motion control functions of NJ, and describes in detail the implementation methods of single-axis and axis group motion control, such as single-axis speed, positioning, gear, cam and other controls, and axis group linear interpolation and circular interpolation control, and provides complete programming examples. Finally, the EtherNet/IP network function of NJ is briefly introduced.
