Abstract

U radu je realizirana regulacija brzine vrtnje servo pogona pomoću industrijskog pretvarača SINAMICS S120 (upravljačka jedinica CU320) te programirljivog logičkog kontrolera S7 1500. Servo pogon se sastoji od sinkronog motora s permanentnim magnetima, a PLC i pretvarač povezani su industrijskom komunikacijom PROFIBUS. Programiranje PLC-a obavljeno je pomoću programa STEP7 unutar programskog okruženja TIA Portal. Također, unutar TIA Portal-a se nalazi program WinCC pomoću kojeg je napravljena aplikacija za upravljanje brzinom vrtnje.
U drugom dijelu zadatka eksperimentalnom optimizacijom regulatora brzine podešeni su parametri regulatora te su snimljeni odzivi brzine, momenta i struja prilikom zaleta reverziranja i terećenja stroja. Za terećenje pogonskog stroja (SMPM-a) kao opteretni stroj korišten je asinkroni motor upravljan frekvencijskim pretvaračem MICROMASTER 420. Snimljeni su i uspoređeni signali u slučaju početno postavljenih i optimalnih parametara regulatora brzine. Signali su obrađeni unutar programa Matlab.

Abstract (english)

Speed control of servo drive using industrial inverter Sinamics S120 (control unit CU320) and programmable logic controller S7-1500 was described by this paper. Servo drive was realized by a permanent magnet synchronous motor. Regarding to PLC and converter, they are connected with PROFIBUS industrial communication. TIA Portal consists of STEP 7, program for programming PLC and WinCC, which was used to make an application for speed control.
Second part of this paper presents experimental optimization of speed regulator. Signals of speed, torque and current were recorded during start up, reversing and with a load. Asynchronous machine, controlled with a inverter Micromaster 420, was used as a load. Signals are recorded and compared in case of initially set and optimal parameters of speed controller. Signals are analyzed with software Matlab.
