I just had one of my motors stop spinning out of the blue and I found out that one of my FOCBOX’s running BLDC just got the DRV8302 error out of nowhere. The other motor running the same settings is running fine. I have already contacted enertion support, but I wanted to see if the community had a faster solution. Attached is a photo of my error.
You can try reflashing the FW on it with either BLDC Tool or the newer VESC Tool. If that doesn’t work, you’ll likely need repairs. Depending on where you’re located there are different options available for repair. If you’re in the US, I’m the closest, but there are plenty of alternatives if you’re in a different area.

Already answered you on the support ticket
I think your FOCBOX is fried due to incorrect values.
1: Batt Max for 10s system will be maximum 30A and yours is 50A which is high for the 10s system.2: ERPM value is also high, recommended value is 60000 and your is 100000 which is high3: Input voltage recommended for FOCBOX is 50.4 maximum, your is 57 which is high.
Please provide the demanded images on the Support ticket
As per my knowledge and tech team, FOCBOX can handle maximum 60A continuous
But due to difference in motor amps and battery amps, it has to be adjusted accordingly
for the 10s and 12s system, our tech team advised that voltage higher than 50.4 will make the system to produce extra heat. (if values are not adjusted accordingly)
50.4 is the recommended value by our tech team.
@CarlCollins Max Input voltage parameter should stay at 57V or else your going to get a few none wanted error. The default parameter from Enertion is 57
@CarlCollins You should really consider letting the guys that KNOW what they are talking about deal with these issues. Your posts are getting ridiculous and I can see why some are reluctant to trust your team.

This ^^^ is about the only thing I can trust from your posts so far.
