style="font-size:14px;">1、上電之前，須確認(rèn)輸入電壓是否有誤，將380V電源接入220V級(jí)變頻器之中會(huì)出現(xiàn)炸機(jī)（炸電容、壓敏電阻、模塊等）；</span> </p> <p> <span

style="font-size:14px;">4、如未顯示故障，首先檢查參數(shù)是否有異常，并將參數(shù)復(fù)歸后，在空載（不接電機(jī)）情況下啟動(dòng)變頻器，并測(cè)試U、V、W三相輸出電壓值。如出現(xiàn)缺相、三相不平衡等情況，則模塊或驅(qū)動(dòng)板等有故障；</span> </p> <p> <span style="font-size:14px;">5、在輸出電壓正常（無(wú)缺相、三相平衡）的情況下，負(fù)載測(cè)試，盡量是滿負(fù)載測(cè)試。</span> </p> <p> <span
