keb科比07F5A1A-YA00变频器炸机无显示维修
科比KEB-F4-S(C)系列变频器维修
科比变频器报E.OH
功率模块过热
功率模块过热。只有在E.nOH下才能复位此故障。
原因:
- 风机堵转
-通风量不足;
-环境温度过高
科比变频器报E.dOH
电机过热
电机PTC过热;只有PTC又变为低阻,在E.ndOH状态下,才能复位故障。
原因:
-端子T1/T2 电阻 > 1650 Ω
-电机过载
度传感器线断了
科比变频器报E.nED
无故障
未发生有定义的故障(不应出此故障)
科比变频器报E.ndOH
电机过热故障解除
电机PTC温度恢复正常,变为低阻
科比变频器报E.PU
功率单元故障
一般是功率电路有故障
