621-6550变频器报故障E.SC驱动电路故障维修案例

a.132变频器报故障ESC驱动电路故障 又是假模块惹得祸，没炸机真是万幸，故障对策，变频器三相输出相间或对地短路，功率模块同桥臂直通，模块损坏，拉闸断电，放电电阻放电，测试逆变主回路，U相下桥臂直通，上桥臂正常，V,W相正常，拆机换U相模块，(这个西门康模块是假的，上次一批买了五个，害人不浅啊，这块还不错，用了一个多月)换一块块富士400A的，测试驱动电路正常，装机试车正常，假模块我无语了。

b.一台30KW变频器以前修好的，放在仓库一直没用，车间一台机子坏了，就把这台变频器装在拉丝机上，开机就报故障ESC。不应该报故障啊，修好的机器放在屋里自己就坏了，拆机取下驱动板，正反面观察没有异常，短接管压降检测电路，连接电源线上电测试，截止负压正常，启动开关测试动态，一开机就报ESC,晕，看来真坏了，复位又开机，还报故障，断电检测驱动板，插针氧化，砂纸打磨，后测试动态正常，试机带负载也正常，变频器运行的环境恶劣，老是遇到奇奇怪怪的故障现象。
