摘要
为了探究如何更方便、准确地实现位置控制,确保其位置控制的精度,探讨了基于西门子S7-200系列PLC和Copley系列伺服系统的位置控制方法。通过介绍系统软硬件构成及其特点,详细论述了PLC系统通过高速脉冲输出、EM253位置控制模块以及自由口通信这三种方式控制伺服电机,以实现绝对运动、相对运动等;同时对它们进行了一系列的比较。实验证明,三种控制方式各有其不同的应用场合,对类似的工业控制具有一定的借鉴参考意义。
In order to explore how to realize more convenient and more precise position control and to ensure the accuracy of position control, the position control method based on Siemens S7-200 PLC and Copley servo system is expounded. Through introducing the compositions and features of hardware and software of the system, three modes to control servo motor for absolute motion and relative motion implemented by PLC are described and compared, i. e. , high speed pulse output, EM253 position control module, and freeport communication. The experimenls prove that three control modes are respectively suitable for different applicable situations; the methods are valuable to be consulted in similar industrial process controls.
