Motor speed control exhibit with frequency changer
 Möhwald, Jiří ; Marada, Tomáš (referee) ; Němec, Zdeněk (advisor)
The following diploma thesis deals with the management of asynchronous motor revolutions by a frequency converter MICROMASTER 440 via the programmable controller S7-200. At the beginning, I researched the company documentation of Siemens, which is the producer of the frequency converter and the programmable controller mentioned above. As my work proceeded, I also started to study the company documentation of Mitsubishi Electric, which produces the operating pannel. The first part of my thesis provides a general description of the stated devices and the second part deals with the solution of the task itself. My task was to design a way of communication between the converter and the controller. I chose a USS protocol via serial port RS-485. The operation of the controller was performed by using an operating terminal type GOT1000 which was connected to the controller. In summary, my diploma thesis primarily deals with the construction of an operating programme for the controller and with creating of a graphical control on the terminal. In the end, I evaluated the knowledge gained during the work on this subject and suggested further procedures.
