The programmable electronic cam has the characteristics of cam mechanism with indexing movement, and has the characteristics of the output motion controlled. In reality production, people can achieve a variety of motion by changing the control algorithm. This paper introduces the MITSUBISHI PLC as the core, the servo motor for the application of electronic cam.%电子凸轮既具备了机械凸轮机构分度运动的特点又有输出运动可控的特点，在现实生产中可以通过改变控制算法实现多种运动规律，提高了生产效率，节约了成本。本文介绍了以三菱PLC为核心，伺服电机为执行件的电子凸轮应用。
