Tambayoyin Fasaha (Technical FAQs)

Q1: Zan iya amfani da na’urar tuki VFD022EL21A ta hanyar ciyar da ita da wutar shigar AC 3-phase na al’ada?

A1: A’a, VFD022EL21A an ƙera ta ne musamman don shigar wutar AC na “single-phase” 200–240 V kaɗai. Zagayen “rectifier” na ciki yana maida wannan single-phase zuwa fitarwa na AC mai matakai uku (3-phase) mai mitar da za a iya daidaitawa domin injinan juyawa na 3-phase.

Q2: Menene babban bambanci tsakanin jerin na’urorin tuki Delta VFD-E da VFD-EL?

A2: Iyali na VFD-EL jerin na’urorin tuki ne ƙanana masu araha waɗanda ke amfani da sarrafa V/Hz scalar tare da haɗaɗɗen dijital “operating interface” a ciki. Jerin VFD-E kuma dandali ne na modular vector micro drive da ke ba da “open-loop vector tracking” kuma yana tallafa wa katunan faɗaɗa (“plug-in expansion cards”).

Q3: Shin resistor ɗin dynamic braking an riga an girka shi ne a cikin ƙarfen Frame B?

A3: Na’urar tana ƙunshe da na’urar sarrafa birkin birki na ciki (chopper), amma babban “heavy-duty” resistor ɗin birki kansa kayan haɗi ne na waje. Don kunna aiki na “active dynamic braking” a kan kaya masu babban juriya (high inertia), dole ne ka zaɓa kaɗaɗɗen resistor ɗin birki na waje daidai da buƙata ka kuma girka shi dabam.
