Re: Wheel encoder to Jaguar Wiring

TIA,

Mike
"I" on the Jaguar refers to Index, a feature of some encoders that helps to "home" the system to a consistent zero location. You can safely ignore it. A->A and B->B. The PID values usually require a bit of experimentation to get right; they depend on the specific motor, the load attached to it, and the gearing between the motor and the sensor.
