摘要
数控系统的点位控制一般用在孔加工机床上,其特点是:机床移动部件能实现由一个位置到另一个位置的精确移动,即准确控制移动部件的终点位置,但并不考虑其运动轨迹。PLC具有抗干扰能力强、可靠性极高、编程方便等显著优点,文章以OMRON公司CP1H-X40D型PLC为例,分析如何利用PLC指令软件编程实现对步进电机的定位/速度控制,提供了实现数控系统中点位控制的经济、有效的具体方法。
Point control of CNC system is generally used in the hole processing machine tool. Its features are as follows： machine moving parts can achieve precise movement from one location to another one, i.e. it can accurately control the final location of moving parts, but it won＇ t consider the motion trajectory. PLC has strong anti-interference ability, high reliability, convenient programming and other significant advantages. In this paper, CPIH-X40D-based PLC of OMRON Corporation is taken as example to analyze how to make use of PLC software programming instructions to achieve the position/speed control of stepper motor. The concrete methods of achieving the point control during the CNC system economically and effectively are given finally.
