SEW變頻器散熱片過熱(oh1)故障原因分析及處理
oh1也是一種比較常見的故障，主要原因：檢查檢查變頻器控制端子(13、12、11)之間是否短路；檢查溫度傳感器檢測(cè)電路是否正常；另外還應(yīng)檢查變頻器的冷卻風(fēng)扇運(yùn)行是否正常；散熱片通風(fēng)情況，散熱片是否有堵塞現(xiàn)象；周圍環(huán)境溫度是否過高。
實(shí)例：一臺(tái)SEW變頻器 ，上電顯示散熱片過熱(oh1)。
分析與維修：因?yàn)槭切掳惭b變頻器，一送電后就有故障，所以變頻器壞的可能性不大；散熱片是無堵塞現(xiàn)象；冷卻風(fēng)扇運(yùn)行正常。斷電后，用萬用表測(cè)試模擬量輸入回路，檢查變頻器控制端子(13、12、11)之間短路，原因是模擬量輸入回路中外接頻率設(shè)定“電位器”電阻值過小所致，更換為wxwxx0.25-1，0.25w 47～4.7k電位器，上電開機(jī)后變頻器運(yùn)行良好，運(yùn)行中沒有再發(fā)生此故障。
變頻器內(nèi)過熱(oh3)故障原因分析及處理
oh3也是一種比較常見的故障，主要原因：負(fù)載是否過大； 變頻器溫度過高故障，如發(fā)生溫度過高報(bào)警，經(jīng)檢查溫度傳感器正常，則可能是干擾引起的，可以把故障屏蔽。另外還應(yīng)檢查變頻器的冷卻風(fēng)扇及散熱片通風(fēng)情況，更換堵轉(zhuǎn)冷卻風(fēng)扇，轉(zhuǎn)動(dòng)慢風(fēng)機(jī)進(jìn)行修復(fù)，清掃變頻器，消除散熱片堵塞；周圍環(huán)境溫度是否過高，降低周圍環(huán)境溫度。對(duì)于其它類型的故障，*好與廠家聯(lián)系，獲得快速可行的解決方法。
