Which error bits to read on Motor fault?

[BTrem.1]

My code reads the motor state and faults after a start-up to ensure the motor is running correctly. I've been using MC_GetCurrentFaultsMotor1() for motor faults but it NEVER reports other than zero. I've primarily been using motor state and speed to determine if a fault occurred.

For example I may read FAULT_NOW (10) or FAULT_OVER (11) but the procedure noted always reports 0. Is there a procedure that reports the most recent fault, even if it has already been cleared?

Perhaps MC_GetCurrentFaultsMotor1 would provide more info.

Might also be that the control software is acknowledging and clearing fault bits. I'm guessing.
