The retraction area indicates the area outside of which collision-free traversing
of the axes must be possible.

Tool change point, which must be approached by the revolver with its zero point.
WCS (Workpiece Coordinate System)
•
MCS (Machine Coordinate System)
•
Notes
The tool change point must be far enough outside the retraction area that it
•
is not possible for any tool to protrude into the retraction area while the re-
volver is moving.
Ensure that the tool change point is relative to the zero point of the revolver
•
and not the tool tip.
