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

Tool change point
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
revolver is moving.
• Ensure that the tool change point is relative to the zero point of the revolver
and not the tool tip.
