ABSTRACT：with the constant improvement of the automation level, more and more industrial location requires accurate positioning. Therefore, how to more convenient, more accurate positioning is the industrial orientation in the field of an important issue. Servo system based on mechanical drive equipment, servo motor as the object of positioning, the locator as the core, in power electronics power converting device for executing agency, under the guidance of the theory of automatic positioning of electric drive automatic positioning system, this kind of positioning motor adjustable speed system, converts electrical energy into mechanical energy, and realize the motion mechanical movement requirements of this article mainly introduced the use of Siemens PLC output analog servo locator, localization of the servo motor speed accurately completed. To improve the reliability and precision positioning of the system. Meet the needs of the industrial field.
