Continuous speed control by PLC controlled motor

Tema ovog rada je kontinuirana regulacija broja okretaja elektromotora upravljana PLC-om. U teorijskom dijelu rada opisani su sustavi automatizacije i tipovi regulatora koji se koriste u industrijskim postrojenjima te njihova primjena. U praktičnom dijelu opisana je konstrukcija i izrada pojedinih dijelova za elektromotor, senzor i kočnicu. Napisan je programski kod za Siemens S7-1200 u programskom paketu TIA PORTAL V15(eng. Totaly Integrated Automation) za mjerenje broja okretaja, PID regulaciju i upravljanje elektromotorom. Međusobna komunikacija uređaja napravljena je koristeći PROFINET(eng. Process Field Net). Nadzor i unos parametara realiziran je na HMI KTP700 Basic PN (eng. Human Machine Interface) ekranu osjetljivom na dodir.The theme of this paper is the continuous control of the number of revolutions of the electric motor operated by the PLC. Theoretical part of the paper describes the automation systems and types of regulators used in industrial plants and their application. The practical part describes the construction and production of individual parts for an electric motor, a sensor and a brake. The software code for the Siemens S7-1200 is written in the TIA PORTAL V15 (Totaly Integrated Automation) package for measuring the speed, PID control and control of the electric motor. The mutual communication of the device was made using PROFINET (Process Field Net). Monitoring and parameter input is realized on the HMI KTP700 Basic PN (Human Machine Interface) touch screen
