If several spindles have been set up, the program can operate at both spin-
dles.

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

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-

er and not the tool tip.

Tool change point Z
The safety clearance defines how close the tool can approach the workpiece
in rapid traverse.
Note
Enter the safety clearance without sign into the incremental dimension.
