當天修復解決西門子變頻器G120報警F30074故障處(chu)理；報警(jing)含義是(shi)通訊(xun)故障 檢測模塊是(shi)不是(shi)通訊(xun)壞了，

變(bian)(bian)頻(pin)器維修檢測(ce)(ce)常用方法。第一(yi)種，測(ce)(ce)試(shi)整(zheng)流電路：找到(dao)變(bian)(bian)頻(pin)器內部直流電源的(de)P端(duan)(duan)和N端(duan)(duan)，將(jiang)(jiang)萬用表(biao)調到(dao)電阻(zu)(zu)(zu)(zu)X10檔(dang)，紅(hong)表(biao)棒(bang)(bang)接(jie)(jie)到(dao)P，黑(hei)表(biao)棒(bang)(bang)分(fen)別依(yi)到(dao)R、S、T，正常時(shi)有(you)幾十歐的(de)阻(zu)(zu)(zu)(zu)值，且(qie)基(ji)本平衡。相反(fan)(fan)將(jiang)(jiang)黑(hei)表(biao)棒(bang)(bang)接(jie)(jie)到(dao)P端(duan)(duan)，紅(hong)表(biao)棒(bang)(bang)依(yi)次接(jie)(jie)到(dao)R、S、T，有(you)一(yi)個接(jie)(jie)近于無窮(qiong)大(da)的(de)阻(zu)(zu)(zu)(zu)值。將(jiang)(jiang)紅(hong)表(biao)棒(bang)(bang)接(jie)(jie)到(dao)N端(duan)(duan)，重(zhong)(zhong)復以上步驟(zou)，都應(ying)得到(dao)相同結果(guo)。如果(guo)阻(zu)(zu)(zu)(zu)值三相不平衡，說明整(zheng)流橋有(you)故障；紅(hong)表(biao)棒(bang)(bang)接(jie)(jie)P端(duan)(duan)時(shi)，電阻(zu)(zu)(zu)(zu)無窮(qiong)大(da)，可以斷定整(zheng)流橋故障或啟(qi)動電阻(zu)(zu)(zu)(zu)出現故障。第二種，測(ce)(ce)試(shi)逆(ni)(ni)變(bian)(bian)電路：將(jiang)(jiang)紅(hong)表(biao)棒(bang)(bang)接(jie)(jie)到(dao)P端(duan)(duan)，黑(hei)表(biao)棒(bang)(bang)分(fen)別接(jie)(jie)U、V、W上，應(ying)該(gai)有(you)幾十歐的(de)阻(zu)(zu)(zu)(zu)值，且(qie)各相阻(zu)(zu)(zu)(zu)值基(ji)本相同，反(fan)(fan)相應(ying)該(gai)為無窮(qiong)大(da)。將(jiang)(jiang)黑(hei)表(biao)棒(bang)(bang)N端(duan)(duan)，重(zhong)(zhong)復以上步驟(zou)應(ying)得到(dao)相同結果(guo)，否則可確定逆(ni)(ni)變(bian)(bian)模(mo)塊(kuai)有(you)故障。
