基于CPLD的数字交流伺服系统接口设计

A design of interface in digital AC servo system based on CPLD

为了解决伺服系统的接口电路结构复杂和可靠性低的问题,研究了一种基于CPLD的接口设计方法;通过对CPLD编程完成大量的逻辑电路设计,简化了接口电路。本设计在工程项目中得到应用,获得了较好的运行效果。

A design of interface in digital AC servo system based on CPLD is presented in this paper to solve the problem that the interface circuit is too complex and fallibility. A large number of logic circuits are designed by CPLD programming,then the interface circuit is simplified. The design has been used in the project and also has well performance.
