Operational Overview
Absolute indexes with Rotary Rollover enabled will take the shortest path to the position entered in the index position parameter.
Note
Absolute indexes move to positions relative to where the machine was homed using the Home, or the DefineHome destination.
Incremental Indexes
An incremental index will move the motor a specified distance in the + or - direction regardless of the starting position. The direction of the incremental index motion is determined by the sign (+ or
Incremental Index

Start Position = 1 Rev
Index Distance = 2 Revs

In the example above, the motor starts at 1 rev, travels a distance of 2 revs and stops at 3 revs. If the same index is initiated a second time, the
