INC Encoder A/B/Z (Z > A) -- for axes that have a wide marker
differential incremental encoder (sometimes called a “non-gated”
encoder). Z > A refers to a wide marker pulse. This means that there is
more than one period during which the A, B, and Z channels can
simultaneously be high. Refer to page 7-50, Figure 7.29 for examples.
Digital systems cannot use this selection.
1326 4--pole Converted Resolver — for 1326 servos equipped with
resolvers attached to either the 9/440 (resolver version) or 1394 drive
(CNC version). This identifies to the CNC that the feedback is from a
1326 four pole resolver that has been converted to an incremental
encoder U/V/W signal.

Notes
Important: Unless you are using optional feedback, these conditions apply:
if (b) ABS Encoder on Digital Module is selected for the AMP
parameter Position Loop Feedback Port then (b) must be selected for
this parameter.
if (c) INC Encoder U/V/W on Digital Module is selected for the AMP
parameter Position Loop Feedback Port then (c) must be selected for
this parameter.
