The encoder ports are intended for systems that use either spindles with
position feedback, to provide positioning feedback if you are using
optional feedback for one of the 1326 servo motors, or to provide feedback
for an analog servo you are controlling from one of the analog output
ports. Up to three encoder ports are available.
Important: If you use encoder 3 (connector J11 accessed through the front
of the system module), resolver 3 (connector J3) is disabled. You can not
use both J3 and J11 at the same time.
