E6,E7故障对于广大用户来说一定不陌生,这是一个比较常见的三菱变频器典型故障,当然损坏原因也是多方面的。 (1)集成电路1302H02损坏。这是一块集成了驱动波形转换,以及多路检测信号于一体的IC集成电路,并有多路信号和CPU板关联,在很多情况下,此集成电路的任何一路信号出现问题都有可能引起E6,E7报警; (2)信号隔离光耦损坏。在IC集成电路1302H02与CPU板之间有多路强弱信号需要隔离,隔离光耦的损坏在元器件的损坏比例中还是相对较高的,所以在出现E6,E7报警时,也要考虑到是否是此类因素造成的; (3)接插件损坏或接插件接触不良。由于CPU板和电源板之间的连接电缆经过几次弯曲后容易出现折断,虚焊等现象,在插头侧如果使用不当也易出现插脚弯曲折断等现象。以上一些原因也都可能造成E6,E7故障的出现。
