In this system ,we need to adjust the speed of electromotor .In order to make full use of energy and satisfy the need of production, considering the adjustment of speed, starting, running and braking. We use the MM 5SE92 of Siemens transducer whose functions of adding or decreasing speeding with high S form and torque promoting can solve the adjustment of speed and starting. This paper firstly introduce the meaning of subjects,summarize the development of configuration software technology, PLC technology and AC frequency conversion for speed adjustment. In the second chapter ,we introduce the structure of transducer arithmetic of controlling ,Basic principle and the advantage of AC frequency conversion for speed adjustment. In the third chapter, we introduce the structure, characteristic flowchart of data disposal of configuration software in detail and particularly introduce the siemens protocol/pro on windows. In the forth chapter, we introduce the structure and flowchart of PLC and introduce particularly the siemens S7 200 PLC and characteristics of software design. In the fifth chapter, we introduce the structure, the configuration of hardware and the implement of software in this system. The Last chapter, we summarise the article and prospect technology correlatively.
