E6,E7故障對(duì)于廣大用戶來(lái)說(shuō)一定不陌生,這是一個(gè)比較常見(jiàn)的三菱變頻器典型故障,當(dāng)然損壞原因也是多方面的。 (1)集成電路1302H02損壞。這是一塊集成了驅(qū)動(dòng)波形轉(zhuǎn)換,以及多路檢測(cè)信號(hào)于一體的IC集成電路,并有多路信號(hào)和CPU板關(guān)聯(lián),在很多情況下,此集成電路的任何一路信號(hào)出現(xiàn)問(wèn)題都有可能引起E6,E7報(bào)警; (2)信號(hào)隔離光耦損壞。在IC集成電路1302H02與CPU板之間有多路強(qiáng)弱信號(hào)需要隔離,隔離光耦的損壞在元器件的損壞比例中還是相對(duì)較高的,所以在出現(xiàn)E6,E7報(bào)警時(shí),也要考慮到是否是此類因素造成的; 。3)接插件損壞或接插件接觸不良。由于CPU板和電源板之間的連接電纜經(jīng)過(guò)幾次彎曲后容易出現(xiàn)折斷,虛焊等現(xiàn)象,在插頭側(cè)如果使用不當(dāng)也易出現(xiàn)插腳彎曲折斷等現(xiàn)象。以上一些原因也都可能造成E6,E7故障的出現(xiàn)。
