西(xi)門(men)子(zi)6SE70變頻器報警F002故(gu)障(zhang)維(wei)修處(chu)理(li)

西門(men)子(zi)6SE70變頻器報警F002（母(mu)線(xian)欠電(dian)壓）故障的常(chang)見原(yuan)因及(ji)排查(zha)方法(fa)如下(xia)：

壹(yi)、故(gu)障原(yuan)因分(fen)析(xi)

熔斷(duan)器燒(shao)毀‌

裝(zhuang)置內(nei)部或(huo)外部熔(rong)斷(duan)器損(sun)壞，導(dao)致電(dian)流無(wu)法(fa)正常(chang)通(tong)過(guo)，需(xu)斷(duan)電(dian)後(hou)使(shi)用(yong)萬(wan)用(yong)表檢測並更(geng)換‌

常(chang)見誘(you)因：電(dian)機(ji)不匹(pi)配(pei)、電(dian)纜對地(di)短路、母(mu)線(xian)接觸(chu)不良‌

電(dian)壓檢測電(dian)路故(gu)障(zhang)‌

檢測電(dian)路中(zhong)分(fen)壓電(dian)阻腐(fu)蝕或(huo)燒毀（潮(chao)濕/腐(fu)蝕環(huan)境(jing)易(yi)發(fa)），導(dao)致電(dian)壓顯示(shi)異(yi)常(chang)‌

CUVC控制板故(gu)障(zhang)‌

CUVC板損(sun)壞(huai)或(huo)分(fen)壓板（位於CUVC下(xia)方(fang)）故障(zhang)，導致電(dian)壓檢測不準(zhun)確(que)‌

母線(xian)電(dian)壓參(can)數(shu)設置錯(cuo)誤(wu)‌

參(can)數(shu)P071（母線(xian)電(dian)壓標定值）設(she)置過(guo)高或(huo)與(yu)實(shi)際輸入(ru)電(dian)壓不匹(pi)配(pei)‌

預(yu)充(chong)電(dian)回(hui)路問(wen)題(ti)‌

預充(chong)電(dian)電(dian)容(rong)損壞(huai)、整(zheng)流(liu)單(dan)元(yuan)未正(zheng)常(chang)輸出(chu)電(dian)壓或(huo)逆變器前端(duan)整(zheng)流(liu)單(dan)元(yuan)故障(zhang)‌

電(dian)源(yuan)輸入(ru)異(yi)常(chang)‌

輸入(ru)電(dian)壓過(guo)低、缺(que)相或(huo)電(dian)網不穩定‌

二、排查(zha)步驟

檢(jian)查(zha)熔斷(duan)器‌

斷(duan)電(dian)後(hou)測量熔斷(duan)器通(tong)斷(duan)，更(geng)換損(sun)壞(huai)件(jian)並排查(zha)燒毀(hui)原(yuan)因‌

驗(yan)證(zheng)輸入(ru)電(dian)壓‌

使(shi)用(yong)萬(wan)用(yong)表測量三相輸入(ru)電(dian)壓（RST端(duan)子(zi)），確(que)認(ren)電(dian)壓穩定在380V±5%‌

檢測分(fen)壓電(dian)阻‌

檢查(zha)靠近熔(rong)斷(duan)器的分(fen)壓電(dian)阻是(shi)否腐(fu)蝕或(huo)開路，必(bi)要(yao)時(shi)更(geng)換‌

參(can)數(shu)校(xiao)準‌

核(he)對參(can)數(shu)P071是(shi)否與(yu)實(shi)際輸入(ru)電(dian)壓壹致（如(ru)380V）‌

硬(ying)件診斷(duan)‌

若上(shang)述正(zheng)常(chang)，需檢(jian)查(zha)CUVC板、整(zheng)流(liu)單(dan)元(yuan)及(ji)預充(chong)電(dian)回(hui)路硬(ying)件狀態‌

三、註意事(shi)項

‌安全操(cao)作(zuo)‌：更(geng)換熔(rong)斷(duan)器或(huo)檢測電(dian)路時(shi)必(bi)須(xu)斷(duan)電(dian)，避免(mian)帶電(dian)作業(ye)‌

環(huan)境(jing)因素‌：潮濕或(huo)腐(fu)蝕環(huan)境(jing)易(yi)導(dao)致電(dian)阻損壞，需加(jia)強(qiang)防(fang)護‌

如(ru)需(xu)進壹(yi)步診斷(duan)，建(jian)議(yi)聯(lian)系專(zhuan)業(ye)維(wei)修人員(yuan)檢測CUVC板或(huo)整流單(dan)元(yuan)硬(ying)件狀態‌
