摘  要
變頻調速以其優異的調速和啟制動性能,高效率、高功率因數和節能效果,廣泛的適用范圍及其他許多優點而被國內外公認為最有發展前途的調速方式,是當今節能、改善工藝流程以提高產品質量和改善環境,推動技術進步的一種主要手段。
可編程程序控制器(簡稱PLC)以其功能完備、組合靈活、編程方便、同時可靠性高、開發周期短而廣泛應用于工業生產與控制的各個領域中。因此，以PLC作為控制系統，大大提高了對交流電機變頻調速的穩定性、可靠性、準確性。同時，由觸摸屏作為控制系統的人機界面，對實時數據、系統動作等進行監控和調整，更加直觀和易操作。
本文設計了基于變頻調速的疲勞實驗裝置，并用三維軟件SolidWorks畫出該系統裝置的三維圖；由三凌PLC編輯程序梯形圖，以實現對系統的各種運動，如連續運動，往復運動，正反轉等；最終由EasyBuilder做出觸摸屏控制的各種人機界面。
關鍵詞：變頻調速； PLC；觸摸屏；往復運動

Abstract
Frequency Control its excellent speed and start-stop performance, high efficiency, high power factor and energy-saving effect, a broad scope of application and many other advantages at home and abroad were recognized as the most promising of the governor, is the energy-saving, improve the process to improve product quality and improving the environment, promote technological progress as a major means.                
Programmable process controller (PLC) for its complete functions, the combination of flexible, easy programming, high reliability, short and exploitation cycles widely used in industrial production and control in all areas. So, using the PLC as control system, it thereby greatly increases the stability, reliability and accuracy of the frequency control of the AC motor. At the same time, the touch-screen control system, as the man-machine interfaces, the real-time data, the system moves to carry out monitoring and adjustment, more intuitive and easy operation.     This paper was designed based on Frequency Control of fatigue experimental device and used 3D SolidWorks software to draw installation of the system of three-dimensional map; Compiled ladder diagram by Mitsubishi PLC to achieve the system's various campaigns, such as continuous movement, reciprocating movement, Positive and; Finally made the touch-screen control of man-machine interface by the EasyBuilder.

Keywords: frequency control; PLC; touch-screen; reciprocating movement.
