Fault: FAULT_CODE_HIGH_OFFSET_CURRENT_SENSOR_3 on VESC 6

Hi there!

I am running a VESC 6 on a dynamometer with different Motors. Very small ones up to kind of large motors.
Power supply is two beefy 12V Lead Acid Batteries in series, so we are around 24V. Motors are run in sensorless FOC, with currents up to 60Amps.

Now, my Inverter suddenly stopped working and I get the Fault: FAULT_CODE_HIGH_OFFSET_CURRENT_SENSOR_3 on startup.

It does not help, if I disconnect the motor.

From looking at the code, I assume that this error is triggered, when the Output voltage of the current sense amplifiers at zero Phase Current differs much from ~1.65V or whatever the "idle" voltage is?

Has any one else encountered this Fault? How to fix?

Thanks,
Jakob
