Abstract
U ovom diplomskom radu realiziran je sustav upravljanja asinkronim elektromotorom koristeći PLC S7 1200 i frekvencijski pretvarač SINAMICS G 120 koji su povezani PROFINET komunikacijom, pri čemu je realiziran jednostavni sustav skalarnog upravljanja elektromotorom promjenom U/f omjera. Komunikacijskim putem PLC dobiva mjerenja brzine, momenta, struje, snage i napona, te statusnu riječ, a zadaje frekvencijskom pretvaraču referencu brzine i jednu upravljaču riječ pomoću koje su realizirane sve upravljačke naredbe. Navedenom sustavu nadograđeno je mjerenje težine upotrebom mjerne opreme SIWAREX koja je realizirana kao sastavni dio PLC-a skupa sa HMI panelom na kojem je riješeno grafičko sučelje za nadzor i upravljanje. Na HMI panelu realizirana su dva načina upravljanja elektromotorom, a to su ručni i automatski gdje u ručnom načinu rada korisnik zadaje referencu motoru sa HMI panela, dok je u automatskom načinu rada referenca mjerena težina skalirana u omjeru od 0 do 5 kg. Kao dokaz ispravnosti realiziranog sustava sve krivulje mjerenja u vremenu snimljene su na HMI panelu u laboratoriju.
Abstract (english)
In this thesis, an asynchronous electric motor control system using a PLC S7 1200 and a SINAMICS G 120 variable frequency drive connected by PROFINET communication is realized, whereby a simple scalar electric motor control system by changing the U / f ratio is realized. Through communication, the PLC receives measurements of speed, torque, current, power and voltage, as well as a status word, and assigns to the variable frequency drive a speed reference and one control word by which all control commands are realized. This system was upgraded with weight measurement using SIWAREX measuring equipment, which was realized as an integral part of the PLC together with the HMI panel on which the graphical interface for monitoring and control was solved. Two modes of electric motor control are realized on the HMI panel, namely manual and automatic where in manual mode the user assigns a reference to the motor from the HMI panel, while in automatic mode the reference measured weight is scaled in the ratio from 0 to 5 kg. As proof of the correctness of the realized system, all measurement curves in time were recorded on the HMI panel in the laboratory.
