Retraction plane X external ∅ (abs) or
retraction plane X referred to XA (inc)
- not for "basic" retraction
retraction plane X internal ∅ (abs) or

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 revolv-
