Abstract

Frekvencijski pretvarači upravljaju i reguliraju rad električnih strojeva, tako što pretvaraju stalni izmjenični napon i frekvenciju u promjenjivi napon i frekvenciju. U radu je prikazan cjelokupni pregled skupine pretvarača Powerflex 525, tehničke karakteristike i funkcijske mogućnosti. Analizirane su sve grupe parametara pretvarača i ispitane su komunikacijske mogućnosti pretvarača. Frekvencijski pretvarač povezan je s PLC-om CompactLogix L30ER i u proizvoljnom simulacijskom modelu testirane su neke mogućnosti pretvarača, kao što je izrada trendova, rad u sekvencama, uspostava komunikacije među elementima. U radu je analizirana zaštitna funkcija „Safe Torque Off“ koja spriječava neželjeno pokretanje motora. Istražene su tehnićke mogućnosti pretvarača Powerflex 525 koje mogu biti primjenjene u sustavima automatizacije.

Abstract (english)

Frequency drives controls and regulates work of electrical machines, they convert standalone AC voltage and frequency to changeable AC voltage and frequency. It has been shown review of group frequency drives Powerflex 525, technical abilities and function abilities. The all group of parameters has been analyzed and communication abilities has tested. Frequency drive has been connected with PLC CompactLogix L30ER, and it has been tested in simulation process. In simulation process there was controlling induction motor in sequnces, making trends in software Studio 5000, and setting up connection between frequency drive, PLC, and PC. This thesis has been analyzed a protect function „Safe Torque Off“, it protects unwanted start of motor. At the end, the all technical abilities has been explored, and they can be used in automation systems.
