Tambayoyin Fasaha (FAQs)

Q1: Menene mafi girman carrier frequency don wannan samfurin 45kW?
A1: Za a iya saita carrier frequency daga 2kHz zuwa 10kHz. Don drive na 45kW, 4kHz ita ce shawarar tsohuwar siga domin daidaita switching losses da hayaniyar mota (acoustic noise).

Q2: Zan iya kunna wannan drive a kan single-phase don gwaji?
A2: A’a. Drives na VP series masu babban ƙarfin wuta suna buƙatar shigar 3-phase mai daidaituwa don guje wa phase-loss protection da yiwuwar lalata gada ta rectifier na shigarwa.

Q3: Yaya “Fire Mode” ke aiki a cikin wannan drive ɗin?
A3: Lokacin da aka kunna ta hanyar digital input, VFD ɗin yana watsar da ƙananan ƙararrawa (masu rashin muhimmanci) kuma yana aiki a wani saurin frequency da aka riga aka saita domin tabbatar da fitar hayaki ko kuma matsin ruwan famfo ya ci gaba da kasancewa a lokacin gaggawa.
