Hello,

While I did tests with my motor control STEVAL-IHM028V2, I made a mistake to schort-circuit the three-phase output ! Then, I smelled a burning smell and no voltage is given in the three-phase output . When I checked the bottom face of the device, I noticed that some resistors (R74, R75 and R69) are burned (see attached images). Also, the W7 and W8 jumpers are short-cicuited. How could I fix this issue ?

N.B. The schematic of the STEVAL-IHM028V2 is attached.

Hello @Tarek_ben,

You can try to replace all of these components (resistors/jumper).
Set a conservative limitation current on your external DC supply.
Verify that DC voltages are correctly generated on the board.
Monitor the current consumption when relaunching test.
