Quadrature Encoder Operation

The Universal Encoder Interface accepts either single or dual quadrature
encoders. Configure the board to accept the encoders through jumpers on J4.

Boards shipped from the factory come default to single quadrature encoder
configuration. For dual encoder configurations, the primary encoder wires to pins
1- 7 on the 1492-IFM20 module.

To select the dual encoder option, remove the CD_QUAD jumper and place it in
PARK. This configures the board to accept two individual quadrature encoders.
In this mode, the drive can switch between encoders for applications such as
Synchronous Transfer between two motors with each having their own encoder.
