西門子直流驅動器不能啟動當天修好恢復;恒稅(shui)電氣公司是較早(zao)從事工(gong)控設備維(wei)修(xiu)單(dan)位,目前(qian)擁(yong)有專業的(de)(de)西(xi)門子維(wei)修(xiu)工(gong)程師和先進的(de)(de)維(wei)修(xiu)設備,具有豐富的(de)(de)維(wei)修(xiu)技(ji)術和經(jing)驗。我們(men)一(yi)直專注維(wei)修(xiu)技(ji)術的(de)(de)研究,保證(zheng)不二(er)次損壞機器(qi),不收取(qu)任何檢(jian)測費用,維(wei)修(xiu)西(xi)門子就找專修(xiu)西(xi)門子公司!
西門子直流驅動器不能啟動當天修好恢復故障處理;不能開機運行,拆開驅動器機殼,上電觀察安裝于機器頂部的3只大風扇運行正常。安裝于機器內部的兩只小型散熱風扇也運轉正常,判斷為 溫度(風扇)檢測電路誤報故障或三線式小風扇內部信號電路損壞,使變頻器誤報過熱故障。為區別是小風扇內部電路損壞還是后續溫度檢測電路異常,將小風扇引線端子CN1端子的2腳和3腳短接后,上電運行正常,說明故障為小風扇內部信號電路損壞,更換同型號三線式風扇后,變頻器運行正常。
同(tong)一機(ji)型的另(ling)一例故障(zhang),檢(jian)測也為小(xiao)風(feng)扇(shan)(shan)損壞,導(dao)致報出OH3故障(zhang)。小(xiao)風(feng)扇(shan)(shan)為三線式(shi)散熱風(feng)扇(shan)(shan),不(bu)能(neng)用(yong)普通兩線式(shi)風(feng)扇(shan)(shan)代換。否則因無運轉信號CPU,會使變(bian)頻器誤報過熱故障(zhang),而(er)不(bu)能(neng)投入運行,因用(yong)客戶急需,將CN7端子的2腳(jiao)和3腳(jiao)短接后,換用(yong)24V二線式(shi)風(feng)扇(shan)(shan),將故障(zhang)應急修復。
