Re: Help with CAN bus closed-loop speed control

We didn't use CAN this year so I may off base with this so keep that in mind...

As far as I know, CAN gives you feedback on current. Current is proportional to torque in a DC motor. That means you can perform feedback and control torque, so you won't be directly controlling speed.
