This is awesome info. I just made a change where it will show every fault that happens rather than just one of them. Also, I can make the rotor test probably 100 times faster now too. Although we know what your rotor time constant is, so you probably never need to run it again. haha. Once you know it, it's fixed for the life of the motor.

In fact, anyone in the country that wants to know what their EVTV rotor time constant is, we can now tell them. It's a critical variable in the FOC code, and is NEVER on the name plate. And in fact even when I've called the motor manufacturers, they never even knew what a rotor time constant was, let alone had the value available.

So, just for posterity, that motor's is about 0.046 seconds.

How is your 24v supply hooked up?
