基于MICRO850PLC的“百米赛跑”设计

Design of “100-meter Race” Based on MICRO850PLC

本文基于罗克韦尔自动化MICRO850可编程控制器,1024滚珠丝杠滑块,Kinetix3伺服电机,Power Flex525变频器和PVC600触摸屏等组成。通过上位机与PLC通讯,输入运行程序,设定参数。由PVC触摸屏输入指定位置信息X,伺服电机通过带动滚珠丝杠滑块旋转,而使被执行对象将以最快的速度向指定位置X运动,且误差不超过±2mm,通过光电旋转编码器确定位置信息和实现运动控制系统的闭环控制,已达到对系统快准稳的要求。

This article is based on Rockwell MICRO850 programmable controller, 1024 ball screw slider, Kinetix3 servo motor, PowerFlex525 Frequency converter and PVC600 touch screen and other components. Through the host computer and PLC communication, enter the running program, set the parameters. The specified position information X is input from the PVC touch screen, and the servo motor is rotated by driving the ball screw slider so that the object to be executed will move to the designated position X at the fastest speed with an error of not more than -＋ 2 mm and determined by the photoelectnc rotary encoder Location information and the realization of motion control system closed-loop control, has reached the system fast quasi-stability requirements.
