具體方法是:用萬(wàn)用表(好是用模擬表)的電阻1K檔,黑表棒接變頻器的直流端(-)極,用紅表棒分別測(cè)量變頻器的三相輸入端和三相輸出端的電阻,其阻值應(yīng)該在5K-10K之間,三相阻值要一樣,輸出端的阻值比輸入端略小一些,并且沒(méi)有充放電現(xiàn)象。然后,反過(guò)來(lái)將紅表棒接變頻器的直流端(+)極,黑表棒分別測(cè)量變頻器三相輸入端和三相輸出端的電阻,其阻值應(yīng)該在5K-10K之間,三相阻值要一樣,輸出端的阻值比輸入端略小一些,并且沒(méi)有充放電現(xiàn)象。否則,說(shuō)明模塊損壞。這時(shí)候不能盲目上電,特別是整流橋損壞或線路板上有明顯的燒損痕跡的情況下尤其禁止上電,以免造成更大的損失。
如果以上測(cè)量西門子變頻器故障結(jié)果表明模塊基本沒(méi)問(wèn)題,可以上電觀察。
1、上電后面板顯示[F231]或[F002](MM3變頻器),這種故障一般有兩種可能。常見(jiàn)的是由于電源驅(qū)動(dòng)板有問(wèn)題,也有少部分是因?yàn)橹骺匕逶斐傻?,可以先換一塊主控板試一試,否則問(wèn)題肯定在電源驅(qū)動(dòng)板部分了。
2、上電后面板無(wú)顯示(MM4變頻器),面板下的指示燈[綠燈不亮,黃燈快閃],這種現(xiàn)象說(shuō)明整流和開(kāi)關(guān)電源工作基本正常,問(wèn)題出在開(kāi)關(guān)電源的某一路不正常(整流二極管擊穿或開(kāi)路,可以用萬(wàn)用表測(cè)量開(kāi)關(guān)電源的幾路整流二極管,很容易發(fā)現(xiàn)問(wèn)題。換一個(gè)相應(yīng)的整流二極管問(wèn)題就解決了。這種問(wèn)題一般是二極管的耐壓偏低,電源脈動(dòng)沖擊造成的。
3、有時(shí)顯示[F0022,F0001,A0501]不定(MM4),敲擊機(jī)殼或動(dòng)一動(dòng)面板和主板時(shí)而能正常,一般屬于接插件的問(wèn)題,檢查一下各部位接插件。也發(fā)現(xiàn)有個(gè)別機(jī)器是因?yàn)榫€路板上的阻容元件質(zhì)量問(wèn)題或焊接不良所致。
4、上電后顯示[-----](MM4),一般是主控板問(wèn)題。多數(shù)情況下?lián)Q一塊主控板問(wèn)題就解決了,一般是因?yàn)橥鈬刂凭€路有強(qiáng)電干擾造成主控板某些元件(如帖片電容、電阻等)損壞所至,或與主控板散熱不好也有一定的關(guān)系。但也有個(gè)別問(wèn)題出在電源板上。
5、上電后顯示正常,一運(yùn)行即顯示過(guò)流。[F0001](MM4)[F002](MM3)即使空載也一樣,一般這種現(xiàn)象說(shuō)明IGBT模塊損壞或驅(qū)動(dòng)板有問(wèn)題,需更換IGBT模塊并仔細(xì)檢查驅(qū)動(dòng)部分后才能再次上電,不然可能因?yàn)轵?qū)動(dòng)板的問(wèn)題造成IGBT模塊再次損壞!這種問(wèn)題的出現(xiàn),一般是因?yàn)樽冾l器多次過(guò)載或電源電壓波動(dòng)較大(特別是偏低)使得變頻器脈動(dòng)電流過(guò)大主控板CPU來(lái)不及反映并采取保護(hù)措施所造成的。
