IGBT temperature detection failure (tH1o)
IGBT hardware failure in temperature detection.
NTC broken or wiring failure.
When the IGBT temperature is higher than the protection level, and detection time exceeds 100 ms, the tH1o protection activates.
Wait for 10 minutes, and then cycle the power. Check if tH1o protection still
exists, check drive hardware.
