Inverter Power Device Fault
Bit 6
The Inverter Power Device Fault bit is set if
the gate driver turns off an output power
device (IGBT) to protect it from an
overcurrent.
Bit 3 in register 202 will also be set.

If an output short circuit occurs, a high current will flow in the IGBT causing its
collector-to-emitter voltage to increase to a level much higher than normal. The
gate driver detects this condition and instantly shuts off the IGBT to prevent its
destruction.
