Re: Wheel encoder to Jaguar Wiring
Hmm... OK, we tried that. Setting kI & kD to 0 and then trying kP at anything > than .8 caused really bad results (back chatter of wheels) at low RPMs. I have to admit that I'm at a bit of a loss as to what's going on. If I have the kP at .35 and kI=0, kD=.003, it runs well at higher RPMs, but doesn't even come close to max voltage according to BD_COMM. Maybe at IRI I can find someone who's using Jaguars to close the loop and they can enlighten me as to what's going wrong.

Some folks are just saying that the Jags just suck. I'm inclined to give the Jags the benefit of the doubt until I talk with others.

Thanks,

Mike
