Axis of Motion simple relative move (cut-to-length application) example

The example program shows a simple relative move that uses the AXISx_CTRL and
AXISx_GOTO subroutines to perform a cut-to-length operation. This program does not
require an RP seek mode or a motion profile, and the length can be measured in either
pulses or engineering units. Enter the length (VD500) and target speed (VD504). When I0.0
(Start) turns on, the machine starts. When I0.1 (Stop) turns on, the machine finishes the
current operation and stops. When I0.2 (E_Stop) turns on, the machine aborts any motion
and immediately stops.
