Graphic Positioning Aid
When traversing to display value zero (in the incremental mode),
ND 522/523 displays a graphic positioning aid.
ND 522/523 displays the graphic positioning aid in a narrow rectangle
underneath the currently active axis. Two triangular marks in the
center of the rectangle symbolize the nominal position to be reached.
A small square symbolizes the axis slide. An arrow indicating the
direction appears in the square while the axis is moving. This indicates
if the axis is moving towards, or away from the nominal position. Note
that the square does not begin to move until the axis slide is near the
nominal position. For setting up the graphic positioning aid. See
"Graphic Positioning Aid" on page 25 under Job Setup.
