Control of the Siemens Sinamics G110 inverter using a PLC SIEMENS S7-1200 and touch panel HMI

U radu je opisan postupak pisanja PLC-programa u razvojnom okruženju TIA PORTAL V15 i način na koji se upravlja FREKVENCIJSKIM PRETVARAČEM za zadani motor da bi motor obavio potrebno kretanje te testiranje rada motora u ručnom i automatskom režimu rada. Prije početka izrade programa u TIA PORTALU potrebno je testirati rad frekvencijskog pretvarača na trofaznom asinkronom motoru. U radu je detaljno opisan postupak spajanja i parametriranja frekvencijskog pretvarača kod upravljanja preko potenciometra ili PLC. Kod upravljanja PLC koristi HMI modul za vizualizaciju. U radu su napravljena dva testiranja: jedno preko potenciometra i jedno preko PLC. Opisan je i dio jednog većeg programa u kojemu su objašnjeni segmenti za upravljanje frekvencijskim pretvaračem. U radu su opisani i dva potprograma. ARHIVA koja služi za pohranu aktivnosti stroja i ALARMI koji čuvaju podatke o nereguliranim stanjima stroja.The paper describes the procedure for writing the PLC program in the development environment of the TIA PORTAL V15 and the way the FREQUENCY TRANSMITTER is controlled for the default motor for the engine to perform the necessary movement and to test the engine operation in the manual and automatic mode of operation. Before the start of the programming in the TIA PORTAL it is necessary to test the operation of a frequency converter to three-phase induction motor. The paper described in detail the process of mergers and parameterization of the frequency converter for control via potentiometer or PLC. With control of PLC HMI module used for visualization. Two tests were carried out: one over the potentiometer and one via the PLC. Described is also part of a larger program in which they explained the segments for management of frequency converter. Two subgraphs are described in the paper. ARCHIVE which serves to store machine activity and ALARMI that keep data on unregulated machine states
