Laboratorní ukázka řízení asynchronního motoru / Laboratory example of synchronous motor control

Vrtal, Václav January 2010 (has links)
This thesis deals with the speed control three-phase asynchronous motor revolutions by a frequency converter Sinamics G110 by way of the programmable automat SIMATIC S7-224XP. Control of programmable automat is realized the operator panel TP 177 micro. Communication between the PLC and frequency converter is realized by USS protocol on bus RS-485. The main goal was to design and implement software, which would allow operation to choose different variations of speed time histories (sinusoid, saw, jump course, etc.), but also the possibility to control the position. Another goal was to create graphical environment for the operator panel that allows manual control, editing and monitoring of engine speed. The last goal was to evaluate the results and summary of findings during commissioning.
