I plugged an additional 1 volt into the analysis mentioned in my earlier post; it makes very little difference with a CIM.
I don't have L values for other motors.

And the more important difference that if your current decays quick enough that you'd start regenerative braking, the diodes will stop that. So the "Forward-Open" mode has an advantage in the (rare) case that a motor is turning fast enough with low enough current that you'd encounter reverse torque.

Good point. That may (or may not) happen with other motors.
