Re: PID control: need D values > 10000??

I don't know much about the Jaguar/CAN PID implementation but I can tell you that your system will act very differently with the load attached. The control loop is electro-mechanical. The numbers you get w/o a load are nearly useless and perhaps why D has little or no effect.
