Re: CAN mode question

From my experience with CAN and the cRIO, the Jaguar has a pinout to connect to an encoder and can handle PID control for you, CAN can still do control essentially like PWM, you can tell the controller to maintain a specific position or a specific speed (using PID).

To the last point of yours, the motor cannot know how far it has turned without some feedback like an encoder or potentiometer.

Was this clear?
