ABB變頻器IGBT功能壞維修(xiu)費(fei)部/ACS800報FF6A出現問題(ti)代(dai)碼維修(xiu)費(fei)部情況(kuang)
洛天依編號FF6A
故障原因
電機負載太低。可能由于傳動機械故障引起。
故障處理
檢查被驅動裝置。
檢查故障功能參數。
變頻器IGBT不導通保護好是(shi)能夠 的檢測達到飽和狀態(tai)壓降，而給實行(xing)單(dan)位的精(jing)力常見是(shi)10us(8倍(bei)過(guo)流)在(zai)上電的時刻簡易 燒(shao)預蓄電阻值(zhi)和駐(zhu)車制動模塊里的IGBT。
供(gong)電局各線路短路故障(zhang)過流，工率單元尺(chi)寸過電壓保護英文(wen)不(bu)明(ming)白敏是具體(ti)緣故，過壓是主要因。
變頻(pin)式式器(qi)進行操作(zuo)過(guo)程中，若(ruo)是 下有(you)臺電(dian)(dian)電(dian)(dian)機功率標(biao)(biao)段發(fa)生已損(sun)壞，原因軸流(liu)風扇直流(liu)電(dian)(dian)機的扭動慣(guan)量巨型(xing)，將發(fa)生 能量是什么就激(ji)動倒灌，發(fa)生強(qiang)過(guo)流(liu)、強(qiang)過(guo)壓，若(ruo)是 變頻(pin)式式器(qi)保(bao)護英文不(bu)按(an)時(shi)將使(shi)2個電(dian)(dian)電(dian)(dian)機功率標(biao)(biao)段的IGBT時(shi)燒損(sun)。
