报警代码：

F0209，F0208，F0205，F020A,F020B,F020C,F020D。

含义：UCE monitoring of one or more power tran-
sistors has tripped due, for example, to a
short circuit or ground fault or because of
defects in the transistor.

检查：

Check the motor cables for a
short circuit or ground fault.
Allow the power unit to cool
down.
If the disturbance keeps oc-
curring, replace the power
unit.

但检查后，IGBT没有问题，通电试机后还是同样地故障，请高手帮忙！不甚感激
