Overview of the capabilities of a modern frequency converter

Asinhronski elektromotorji so največkrat uporabljeni eletromotorji. Njihova največja slabost je, da jim ne moremo enostavno spreminjati vrtilne hitrosti. Z uporabo frekvenčega pretvornika je problem upravljanja vrtilne hitrosti enostavno odpravljen. V diplomski nalogi so predstavljene nekatere zmožnosti modernega frekvenčnega pretvornika. Ker pa imajo danes ti frekvenčniki veliko funkcij, se jih najlažje krmili kar preko računalniške programske opreme. V našem primeru je bil to programski paket CX-drive, preko katerega krmilimo elektromotor. Uporabimo pa lahko tudi že v frekvenčnik vgrajen PID krmilnik.Asynchronous motors are the most commonly used electric motors. Their biggest disadvantage is that we can not change their rotational speed easily. If using a frequency converter, the problem of rotational speed control is simply solved. The thesis presents some of the capabilities of a modern frequency converter. Since these frequency converters have many functions today, they are best controlled through computer software. In our case, the CX-drive software package was used to control the electric motor. Our frequency converter also makes it possible to use PID controller integrated in the frequency converter
