Návrh ovládání elektrického pohonu s frekvenčním měničem.

Abstract

This diploma thesis deals with the issue of frequency converters with the possibility of control using HMI touch panels. This thesis examines the possibilities of control and operation of an electric drive with a frequency converter using a combination of an HMI control panel and a control programmable logic controller. The theoretical part is focused on the analysis of management options and control of the frequency inverters via the Profinet communication bus, the standardized PROFIdrive profile, the relevant telegram, the HMI control panels and the master control unit. The practical part is focused on the complete design of a learning workplace for control, operation and parameterization of a selected electric drive. The project documentation contains the design of the control cabinet together with the protocol on the determination of external influences and the assessment and reduction of the risk of the selected workplace. The software part includes the visualization of the HMI touch panel, the parameterization of the frequency converter and main program of the control part of the programmable logic controller.
