Abstract:With small Germany Siemens S7-200 programmable logic controller of the central processing unit, with stepping motor as control object. This paper introduces the concept of PLC principle and advantage of the control, the concept and working principle of stepper motor, the current situation and development direction. bined with stepper motor has a high research value and significance. In this paper, based on the introduction to the characteristics of the stepper motor control, step motor control strategies are researched. Design the hardware of the control system scheme, and write the corresponding control process, test the actual control effect, and puts forward the corresponding rectification measures, achieve more reasonable and efficient. For using stepper drive stepper control system, the controller of stepper motor control is the key to control the generation of pulse signal. This paper introduces the control using the controller a variety of different implementation methods of the pulse signal, then the method to realize different control the stepper motor.
Key words: Programmable logic controller; Stepping motor; The control strategy; Control the process
引言
伴随着经济的快速发展,科技的日新月异,产品更新换代周期缩短,生产效率有了更高的要求,特别是计算机技术的广泛的推广和普及,信息产业发挥了它无与伦比的优越性和高效性,其中可编程逻辑器件就有了更多的用武之地。
可编程序控制器(programmable logic controller),俗称PLC,它是一种基于数字运算操作的电子系统,现在在工业环境设计中它产生了很高的价值,并带来了很大的效益。PLC在工业控制领域得到了广泛的应用, 同时微电子技术和计算机技术的更新,其功能也相应的得到了很大的发展,PLC已经不再局限于逻辑控制、顺序控制的普通技术层面,现在已经深入到模拟量控制,甚至远程通信功能等高技术领域。所以PLC与CAD/CAM、机器人技术一起被称为当代工业自动
