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