Data description
9.2 Cycle data
Coupling spindle position with coordinate rotation in active plane for workpiece measurement with
multi probe
_CHBIT[13]=0:
_CHBIT[13]=1:
NOTICE
If additional rotations are active in the other planes/axes, then this function is not effective!
The coupling between the coordinate rotation and spindle position is generally not
executed:
• Rotations around abscissa or ordinates between calibrating and measuring are not
• There is no position-controlled machining spindle
• Monoprobes are used (_PRNUM = x1xx)
Adapt spindle positioning, if _CHBIT[13]=1
_CHBIT[14]=0:
_CHBIT[14]=1:
Note
A coordinate rotation in the active plane is:
• one rotation around the Z axis with G17,
• one rotation around the Y axis with G18 or
• one rotation around the X axis with G19.

OFF
There is no coupling between the spindle position and active coordinate rotation
in the plane.
ON
When multi-probes are being used, the spindle is positioned depending on the
active coordinate rotation in the plane (rotation around the applicate (feed axis))
so that the same positions of the probe sphere are probed when calibrating and
measuring.
Note: Pay attention to _CHBIT[14]!
identical
Spindle positioning is undertaken acc. to the default.
Angle of coordinate rotation in the plane 0°: Spindle positioning 0°
Angle of coordinate rotation in the plane 90°: Spindle positioning 270°
Spindle positioning is undertaken in reverse.
Angle of coordinate rotation in the plane 0°: Spindle positioning 0°
Angle of coordinate rotation in the plane 90°: Spindle positioning 90°
