Controller motor asincron proiect VFD

Recommended Posts

Ce vise frumoase....app ati vazut vreodata cat de lunga e lista de setup la un VFD? sau macar cum arata placa? La Demag sunt in jur de 890 parametri care trebuie setati iar la SEW mult mai multi...chiar si modelele vechi cu caracteristica U/f tot au vreo 30-50 setari principale. Cine a reparat macar cateva sute de VFD_uri stie ce vreau sa spun.

Visele pot deveni realitate...

Invertorul va avea PFC in fata (doar ca va fi controlat de acelasi uC - nu este obligatoriu solutia PFC o am in vechea practica si merge foarte bine)...adica un chopper din 220VAC in 350VDC.

Partea de invertor ma cam supara...am incercat o gramada de chestii pe DSPic insa imi cam variaza tensiunea intre faze(automat si curentul)
