基于PLC的步进电机控制系统设计

Design of the Step Motor Control System Based on PLC

以S7-200PLC为控制核心设计了一套步进电机控制系统,利用S7-200系列PLC的高速脉冲输出信号及方向信号对步进电机进行直接运动控制.给出了PLC控制的I/O端子接线图和梯形图程序.试验证明,采用该方案可以满足步进电动机的控制需要,对于相关行业或领域实现步进电机的精确定位控制具有较好的应用与参考价值.

In this paper,a control system of stepping motor is designed based on the control core of S7-200 PLC.By using the high speed pulse output signal and direction signal of S7-200 series of PLC,the direct motion of stepper motor is controlled.The procedures of I/O terminal wiring diagram and ladder diagram controlled PLC are given out.The test results show that the scheme can meet the control needs of the stepper motor,and has a good application and reference value for the precise positioning control of the stepper motor in the relevant industries or fields.
