Has anyone ever set up the back-emf features on a digitrax decoder? It seemed like a bit of work going through the three CV's and indvidually incrementing them to find the correct value as described in the instructions. Is it worth it?
I tried turning them up pretty high and I still had to crank the throttle up to get it to move. I was expecting that the back-EMF would help the motor get started at slower speeds. My understanding was that when the engine starts off at a low voltage that isn't quite enough to turn over the motor the decoder should keep increasing the voltage until the motor turns over and generates some back-EMF that is consistent with low voltage that is being applied to it. Is that how it is supposed to work?
