Hello,
What is the Feedback Calibration Fault, and what causes it?
I have a system that's been running since January, I was running a motor validation yesterday - max torque for 0.5min, then 0 torque for 9.5min. After 3.5 hours I noticed my B phase current went to my full scale value of 410.7A, and my system faulted. I power cycled my system, and my MCU had the Feedback Calibration Fault. I tried another MCU, and it had the same fault. It seems something about the system is causing this fault. I replaced the system, and the fault went away.
That fault indicates that there is an issue with the hardware. I usually means that the value read by the MCU when the current is zero isn't approximately at the midpoint of the ADC voltage range.
Thanks Adam. That was the case as well, since the hardware was stuck at 4095.
