That test isn't using regen to slow the motor down. But it would be a good idea. All it's doing is setting IdRef and IqRef to 300, and letting the motor run as fast as it can. Each rotor time constant candidate gets 5 seconds to do its best RPM, and it just starts at whereever the last guy left off. If you got a motor overspeed fault when it was set to 10,000, that means that during one of those 5 second times, the motor got to 10000!, and you evidently didn't get to hear about it because of the fault. holy crap. what voltage/current is this motor rated for? That test is trying to see 44 amps for Id and 44 amps for Iq.

Your motor is much more powerful than mine, and the acceleration is more severe. I think I'm going to include a softer ramp, at least for testing. It will make it easier for things to stay under control.
