S7-1200 PLC在伺服电动机位置控制中的应用

随着生产技术的提升,工艺领域对伺服电动机的运动控制模块要求更加精确的位置控制,西门子公司的SIMATIC S7-1200PLC有着良好的工艺和性能,其通过脉冲接口的方式给电机的运行控制提供支持,满足当前工艺要求的水平,并且功能完善。文中对西门子S7-1200 PLC在松下伺服电动机位置控制中的应用进行研究,阐述了松下伺服电动机A5系列硬件和PLC系统的接线步骤,通过软件程序实现对伺服电动机的位移运动的控制。实验验证了程序的正确性,结果表明,位移的操作精准度可以达到0.1 mm,满足位置控制的性能要求。

Application of S7-1200 PLC in Position Control of Servo Motor

With the improvement of production technology, the motion control module of servo motor requires more precise position control. The SIMATIC S7-1200PLC designed and developed by Siemens has good modern process performance. It is given by pulse interface. The motor’s operational control functions are supported to meet current process requirements and are fully functional. This paper studied the application of SIEMENS S7-1200 PLC in the position control of Panasonic servo motor. This paper firstly explained the wiring steps of Panasonic servo motor A5 series hardware and PLC system, and then controled the displacement motion of servo motor through software program. Finally, the experiment was used to verify the correctness of the program. The results showed that the accuracy of the displacement operation could reach 0.1 mm, which could meet the performance requirements of position control.
