西門子(zi)的(de)(de)Micromaster 430變頻(pin)(pin)器(qi)(qi)(qi)故(gu)(gu)(gu)障(zhang)(zhang)(zhang)報(bao)警(jing)，設備(bei)無法啟動(dong)，故(gu)(gu)(gu)障(zhang)(zhang)(zhang)代碼為F0001，查完說明書后(hou)發(fa)現(xian)(xian)(xian)F0001為過流故(gu)(gu)(gu)障(zhang)(zhang)(zhang)。到(dao)現(xian)(xian)(xian)場后(hou)發(fa)現(xian)(xian)(xian)變頻(pin)(pin)器(qi)(qi)(qi)報(bao)警(jing)信(xin)號不(bu)止一個(ge)(ge)，是F0001和A0503在變頻(pin)(pin)器(qi)(qi)(qi)面板上(shang)交替(ti)出(chu)現(xian)(xian)(xian)，而A0503表示的(de)(de)欠(qian)壓限幅(fu)故(gu)(gu)(gu)障(zhang)(zhang)(zhang)，人機(ji)(ji)(ji)界(jie)面上(shang)顯示的(de)(de)是風(feng)機(ji)(ji)(ji)故(gu)(gu)(gu)障(zhang)(zhang)(zhang)，點擊復位(wei)沒(mei)有(you)反應。隨后(hou)嘗試斷(duan)電(dian)(dian)(dian)(dian)復位(wei)，把(ba)(ba)風(feng)機(ji)(ji)(ji)主電(dian)(dian)(dian)(dian)路(lu)空氣開關斷(duan)電(dian)(dian)(dian)(dian)，plc控(kong)制(zhi)電(dian)(dian)(dian)(dian)路(lu)斷(duan)電(dian)(dian)(dian)(dian)，重(zhong)新啟動(dong)后(hou)故(gu)(gu)(gu)障(zhang)(zhang)(zhang)仍然(ran)沒(mei)有(you)解除(chu)(chu)。考慮到(dao)過流報(bao)警(jing)有(you)可能是接地(di)故(gu)(gu)(gu)障(zhang)(zhang)(zhang)，把(ba)(ba)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)接線(xian)端(duan)(duan)子(zi)打開，用搖(yao)表測量各(ge)個(ge)(ge)端(duan)(duan)子(zi)對地(di)的(de)(de)阻(zu)值，對地(di)均良好，沒(mei)有(you)發(fa)現(xian)(xian)(xian)異(yi)常。但是發(fa)現(xian)(xian)(xian)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)沒(mei)有(you)接地(di)線(xian)，由于電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)與控(kong)制(zhi)柜(ju)(ju)之間(jian)的(de)(de)距離(li)太長(chang)，短時(shi)間(jian)內(nei)無法安裝電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)至變頻(pin)(pin)器(qi)(qi)(qi)之間(jian)的(de)(de)導(dao)線(xian)，暫時(shi)沒(mei)有(you)布線(xian)。到(dao)控(kong)制(zhi)柜(ju)(ju)仔細觀察后(hou)發(fa)現(xian)(xian)(xian)控(kong)制(zhi)柜(ju)(ju)內(nei)灰塵較多，便(bian)用壓縮空氣清掃(sao)灰塵，除(chu)(chu)塵后(hou)再(zai)次啟動(dong)，故(gu)(gu)(gu)障(zhang)(zhang)(zhang)仍然(ran)沒(mei)有(you)解除(chu)(chu)。zui后(hou)為了(le)排(pai)查是電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)的(de)(de)故(gu)(gu)(gu)障(zhang)(zhang)(zhang)還是變頻(pin)(pin)器(qi)(qi)(qi)的(de)(de)故(gu)(gu)(gu)障(zhang)(zhang)(zhang)，拆除(chu)(chu)了(le)變頻(pin)(pin)器(qi)(qi)(qi)的(de)(de)出(chu)線(xian)，啟動(dong)后(hou)發(fa)現(xian)(xian)(xian)故(gu)(gu)(gu)障(zhang)(zhang)(zhang)解除(chu)(chu)，重(zhong)新連接變頻(pin)(pin)器(qi)(qi)(qi)出(chu)線(xian)后(hou)，變頻(pin)(pin)器(qi)(qi)(qi)面板不(bu)再(zai)報(bao)警(jing)，人機(ji)(ji)(ji)界(jie)面的(de)(de)報(bao)警(jing)也已(yi)經解除(chu)(chu)。

我們在分析這次故(gu)障(zhang)的(de)(de)(de)(de)原因的(de)(de)(de)(de)時候，百思不(bu)得其解，為什么(me)將所有的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)都斷(duan)電(dian)(dian)(dian)(dian)變頻(pin)(pin)器(qi)還是不(bu)能復(fu)(fu)位，而zui后拆除了(le)(le)變頻(pin)(pin)器(qi)至電(dian)(dian)(dian)(dian)機(ji)的(de)(de)(de)(de)導線(xian)又重(zhong)新安(an)裝，變頻(pin)(pin)器(qi)就神奇的(de)(de)(de)(de)復(fu)(fu)位了(le)(le)。為了(le)(le)解決這個困惑看，我打了(le)(le)西(xi)門(men)子技(ji)術(shu)服務(wu)的(de)(de)(de)(de)，工(gong)程師給(gei)了(le)(le)我滿意的(de)(de)(de)(de)答案：1.變頻(pin)(pin)器(qi)工(gong)作的(de)(de)(de)(de)環(huan)境中有太多的(de)(de)(de)(de)灰(hui)塵(chen)，灰(hui)塵(chen)集聚(ju)產生(sheng)了(le)(le)靜電(dian)(dian)(dian)(dian)，變頻(pin)(pin)器(qi)受到了(le)(le)靜電(dian)(dian)(dian)(dian)的(de)(de)(de)(de)干擾導致無(wu)法(fa)(fa)正常復(fu)(fu)位；2.變頻(pin)(pin)器(qi)與(yu)電(dian)(dian)(dian)(dian)機(ji)之間缺少地(di)線(xian)，接地(di)故(gu)障(zhang)導致變頻(pin)(pin)器(qi)無(wu)法(fa)(fa)正常使用。建(jian)議我們*清掃控制柜，并且(qie)增加變頻(pin)(pin)器(qi)與(yu)電(dian)(dian)(dian)(dian)機(ji)之間的(de)(de)(de)(de)接地(di)線(xian)。
