Yes, I just close a contactor to the 24V circuit - no DC controller - to run the Warp9 DC motor. That's why it is a separate battery pack, and why it is such a low voltage. The unloaded speed of the DC motor is about 3600 rpm so I don't overspeed the motor if something goes wrong (like I blow a fuse on the AC)

Slow down the AC with 1<ENTER> on this firmware. Using a 20 turn pot will be more convenient but likely less accurate!

I could also kill the 12V to the AC controller after the AC Controller brings the AC motor to a stop, before it starts to accelerate in reverse.

Looking forward to the firmware that recognizes the change in direction. I think I read somewhere above that you would add a couple of lines of code so that a car would not accelerate in reverse at a stop light
