Positioning of electrical drive with induction motor using control unit Sinamics CU320 and programmable logic controller S7-1200

Korištenjem programirljivog logičkog kontrolera S7-1200, pretvarača napona i frekvencije SINAMICS S120, programskih paketa Starter i TIA Portal ostvaren je sustav za pozicioniranje asinkronom strojem. Opisana je korištena oprema i softver te je prikazano nihovo korištenje. Upotrebom programskog paketa Starter pokazano je kako konfigurirati i parametrirati neizravni četverokvadrantni izmjenični pretvarač. Prikazano je apsolutno i relativno pozicioniranje te pozicioniranje putem programskih blokova. Posebno je obrađena mogućnost programiranja programskih blokova čija je primjena široka u industriji. Korištenjem telegrama 111 koji je prvenstveno namjenjen za funkcijski modul EPos Basic Positioner je ostvarno pozicioniranje putem PLC-a. Koristeći programski paket TIA Portal objašnjen je proces stvaranja projekta, dodavanja uređaja, uspostave komunikacije (PROFIBUS i Ethernet odnosno PROFINET), programiranja PLC-a u ladder programskom jeziku te na kraju dizajniranja grafičkog sučelja za upravljanje i nadzor pozicioniranja korištenjem integriranog programa WinCC.Using the programmable logic controller S7-1200, frequency converter SINAMICS S120, Starter software and TIA Portal software a positioning system with an asynchronous motor has been accomplished. The used equipment and software have been described, and their use has been shown. Using the Starter software package it is shown how to parameterize and configure the AC coverter. Absolute and relative positioning and positioning using traversing blocks was represented. A special attention was given to traversing blocks whose application has a wide range in industry. Using the Siemens telegram 111 which was primarily made for the EPos Basic Positioner function module a positioning system via PLC was established. By using the TIA Portal software package the process of creating a project, adding devices, establishing communication (PROFIBUS and Ethernet), programming the PLC in ladder programming language and finally designing a graphical interface for managing and monitoring positioning using integrated software WinCC was thoroughly explained
