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

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 revolv-
er and not the tool tip.
