摘要
本文介绍了一种基于单片机为控制器,结合专用运动控制芯片LM629构成的全数字化位置伺服系统。单片机主要完成对系统进行故障检测、自动保护、系统参数给定、状态显示等控制管理工作;PWM脉冲由专用芯片LM629产生并驱动主回路,系统硬件结构简单;由于速度线生成和PID调节由LM629硬件完成,系统软件编程得到了大大简化。
This article introduces a kind of total numerical position serve system with microcomputer and special move control chip LM629, The microcomputer's main job is to complete the system' s Fault detection test , Automatic protection system parameter give, situation display etc. The PWM pulses come from chip LM629 and drives the main circuit. The structure of the system hardware is simple and system software development gets to simply, because speed line's bom and the PID control are completed by the LM629.
