西門子S120驅動器(qi)雙(shuang)軸(zhou)18A報接地(di)RDY亮紅燈修(xiu)復(fu)解決,西門子數控(kong)系統,數控(kong)機床,加工中心,鏜銑床,數控(kong)磨床維(wei)修(xiu),
F30021 功率(lv)部件(jian)接(jie)地(di)(包括功率(lv)線接(jie)地(di)、電機(ji)接(jie)地(di)或(huo)短路(lu)、變(bian)流器損壞)
對于像你這(zhe)樣的書本型120變頻器很(hen)容易出(chu)現此類故(gu)障,有(you)時斷一(yi)下(xia)CU和功率模塊(kuai)的電源,再(zai)送電即(ji)可(ke)恢復,但使用幾(ji)天還會(hui)出(chu)現。只有(you)更換功率模塊(kuai)解決。
對(dui)于裝機裝柜(ju)(ju)型(xing)(xing)S120變頻(pin)器,出現此(ci)故障(zhang)多數(shu)情況(kuang)更換CIB板(ban)即可。但除此(ci)故障(zhang)幾率很小。我這里維修100多臺S120變頻(pin)器五(wu)年了,只有兩個裝柜(ju)(ju)型(xing)(xing)出現過此(ci)類故障(zhang),都(dou)是更換CIB,但是書(shu)本型(xing)(xing)已壞了四臺。
我個人感覺(jue)書本型損壞原因:因為變頻器很小,多數(shu)用于輔助傳(chuan)動(dong),負載被拖(tuo)動(dong),就容(rong)易出現此故障。
另外,如果你(ni)有(you)能力(li),此(ci)類故障的變頻器修復很容易。

1 器件(jian)松動(dong)或(huo)堵(du)塞故障
(1)西(xi)門子 840D 數控(kong)系統正常運(yun)行(xing)時(shi),Z 軸出(chu)現(xian)振動(dong)、定(ding)位(wei)不故障(zhang)。故障(zhang)發(fa)生時(shi),系統仍(reng)處于(yu)正常運(yun)行(xing)狀(zhuang)(zhuang)態,因此判(pan)斷系統的(de)電氣(qi)部分不會存在故障(zhang),故障(zhang)由機械部分引起,拆卸(xie)傳動(dong)箱后(hou)發(fa)現(xian)齒輪(lun)沒(mei)有出(chu)現(xian)異常狀(zhuang)(zhuang)況(kuang),但尺座的(de)螺(luo)釘出(chu)現(xian)晃動(dong),存在移位(wei)錯位(wei)現(xian)象。重(zhong)新擰緊固定(ding)螺(luo)釘后(hou),重(zhong)啟(qi)西(xi)門子 840D 數控(kong)系統,設備運(yun)行(xing)正常。
(2)西門子 840D 數控系(xi)統運(yun)行(xing)過(guo)程(cheng)中,潤滑突然暫停,系(xi)統預警報警開(kai)始閃爍,系(xi)統停止運(yun)行(xing)。因(yin)為系(xi)統具(ju)備(bei)狀態監控功(gong)能,可(ke)以對系(xi)統潤滑體系(xi)進行(xing)全面監控,所以故(gu)障可(ke)以由以下原因(yin)引起:
①潤(run)滑(hua)油不足,引起開關自動(dong)關閉(bi);
②潤(run)滑油路泄漏:
③潤滑油(you)(you)油(you)(you)路堵塞;
④潤滑(hua)油泵電機過量(liang)加載;
⑤壓(ya)力開(kai)關敏感性(xing)降低。故障維修時(shi),首先檢(jian)查壓(ya)力開(kai)關,發現(xian)(xian)壓(ya)力開(kai)關沒有異常(chang)狀況,能夠(gou)正常(chang)使用,然后(hou)進行油箱被(bei)潤滑部分的檢(jian)查,發現(xian)(xian)該部分沒有被(bei)潤滑油潤滑,進一步檢(jian)查發現(xian)(xian)油管管道堵(du)塞,將堵(du)塞物清除后(hou),系統恢復(fu)正常(chang)。
(3) 某工(gong)廠假期后復工(gong),西(xi)門子(zi) 840D 數(shu)控系(xi)統重(zhong)新啟動(dong)時,3 個給進(jin)軸(zhou)都沒有正(zheng)常(chang)(chang)反(fan)應,但系(xi)統指示(shi)燈(deng)處于亮(liang)起(qi)狀態(tai)。一般情(qing)況下,系(xi)統 3 個給進(jin)軸(zhou)的(de)(de)運(yun)動(dong)狀態(tai)始(shi)終保持一致(zhi),這一故(gu)障出(chu)現(xian)的(de)(de)原因在于總控制位置(zhi)出(chu)現(xian)異常(chang)(chang)。首(shou)先打開系(xi)統電氣(qi)柜進(jin)行(xing)檢(jian)查,發(fa)現(xian)電氣(qi)柜板面有預警提(ti)示(shi)以(yi)及低壓(ya)提(ti)示(shi),由此可以(yi)看(kan)出(chu),系(xi)統電源或(huo)者電壓(ya)出(chu)現(xian)故(gu)障。使用萬用表依次測量 3 個給進(jin)軸(zhou)的(de)(de)電壓(ya),測量的(de)(de)結(jie)果顯示(shi),1 軸(zhou)的(de)(de)電壓(ya)遠(yuan)小于另外兩軸(zhou)的(de)(de)電壓(ya),在深入(ru)檢(jian)查 1 軸(zhou)之(zhi)后發(fa)現(xian)該軸(zhou)接線位置(zhi)有松動(dong)現(xian)象,將電氣(qi)接線位置(zhi)重(zhong)新加固(gu)后,西(xi)門子(zi) 840D 數(shu)控系(xi)統恢復正(zheng)常(chang)(chang)。
2 主軸異常響動
(1)在 611D 伺服驅動(dong)(dong)下,系(xi)統(tong)(tong)(tong)主(zhu)軸(zhou)旋(xuan)轉時發(fa)(fa)出(chu)噠噠的異常聲響,調低主(zhu)軸(zhou)轉速后,仍舊存在異常聲響,聲響維(wei)持一(yi)段(duan)時間(jian)后系(xi)統(tong)(tong)(tong)報警(jing)。首先對主(zhu)軸(zhou)機械(xie)部(bu)(bu)位(wei)進行(xing)(xing)全面檢查,沒有發(fa)(fa)現任何機械(xie)損(sun)傷;使用(yong)表檢查主(zhu)軸(zhou)的電(dian)機線(xian)圈(quan)正常。判斷故障部(bu)(bu)位(wei)是(shi)主(zhu)軸(zhou)驅動(dong)(dong)器(qi)(qi)或編(bian)碼器(qi)(qi),拆卸(xie)驅動(dong)(dong)器(qi)(qi)后發(fa)(fa)現該器(qi)(qi)件(jian)散熱孔被灰塵覆蓋,IGBT 模塊在高溫(wen)狀況下被燒毀。將驅動(dong)(dong)器(qi)(qi)維(wei)修后啟動(dong)(dong)西門子 840D 數控系(xi)統(tong)(tong)(tong),系(xi)統(tong)(tong)(tong)恢復正常運(yun)行(xing)(xing)。由此得出(chu),運(yun)維(wei)人員需要定(ding)期進行(xing)(xing)系(xi)統(tong)(tong)(tong)維(wei)護,清理灰塵,保障系(xi)統(tong)(tong)(tong)的穩定(ding)運(yun)行(xing)(xing)。
(2)系(xi)統正(zheng)常(chang)(chang)運行(xing)時,當(dang)主(zhu)(zhu)軸(zhou)的(de)轉速(su)(su)(su)(su)設置<430 r/min 時出現異(yi)常(chang)(chang)聲(sheng)響,且系(xi)統功(gong)率出現較大變(bian)化,當(dang)主(zhu)(zhu)軸(zhou)的(de)轉速(su)(su)(su)(su)設置為(wei)1200 r/min 時,異(yi)常(chang)(chang)聲(sheng)響消失,過程(cheng)中系(xi)統沒有(you)報警(jing)。一般情況下,判斷故障可(ke)能由(you)控制(zhi)器、控制(zhi)電(dian)(dian)機(ji)或變(bian)速(su)(su)(su)(su)箱(xiang)引(yin)起(qi)。依次檢(jian)查(cha)元器件,控制(zhi)器和電(dian)(dian)機(ji)正(zheng)常(chang)(chang)。當(dang)檢(jian)測傳(chuan)動(dong)裝置時,主(zhu)(zhu)軸(zhou)轉速(su)(su)(su)(su)設定為(wei)低速(su)(su)(su)(su)(300 r/min)或高速(su)(su)(su)(su)(2100 r/min)時,電(dian)(dian)機(ji)的(de)轉速(su)(su)(su)(su)一致,但當(dang)主(zhu)(zhu)軸(zhou)低速(su)(su)(su)(su)運行(xing)時,主(zhu)(zhu)要是根據(ju)變(bian)速(su)(su)(su)(su)箱(xiang)內的(de)齒(chi)輪進行(xing)減(jian)速(su)(su)(su)(su),表明主(zhu)(zhu)軸(zhou)異(yi)常(chang)(chang)聲(sheng)響由(you)變(bian)速(su)(su)(su)(su)箱(xiang)引(yin)起(qi)。更換(huan)變(bian)速(su)(su)(su)(su)箱(xiang)后,系(xi)統恢復正(zheng)常(chang)(chang)。
3 電源(yuan)故障
611D 伺(si)服驅(qu)動(dong)時(shi)(shi),將主軸轉(zhuan)速設定為 3000 r/min,進(jin)行設備(bei)的啟動(dong),此時(shi)(shi)系統(tong)處于正常運行狀態,但(dan)當系統(tong)轉(zhuan)速>3000 r/min進(jin)行轉(zhuan)剎車時(shi)(shi),611D 電源單元出現(xian)錯(cuo)誤(wu),進(jin)行過電壓的報警(jing),系
統(tong)停止運行(xing)。對系(xi)統(tong)進行(xing)全面的檢查(cha)后(hou)(hou)沒有發現機械異常(chang)(chang)狀況(kuang),電(dian)路板與(yu)元(yuan)件均處于(yu)正(zheng)常(chang)(chang)狀態,更換(huan) 611D 電(dian)源(yuan)單(dan)元(yuan)之后(hou)(hou),出現故(gu)障轉移現象,更換(huan)出現故(gu)障的電(dian)源(yuan)單(dan)元(yuan)后(hou)(hou),系(xi)統(tong)恢復正(zheng)常(chang)(chang)運行(xing)。
