Corrections after measurement of the zero point

If you store the workpiece zero in a work offset, changes to the coordinate system or axis
positions might be necessary in the following cases.
● Correcting the work offset causes the workpiece coordinate system to rotate, after which
● Correcting the work offset necessitates positioning of the rotary axis in order to align the
Activation windows help you to adapt the coordinate system and the axis positions.
Procedure
Activating work offset
Aligning and retracting the tool (for aligning the plane)

Press the "Back" softkey.
The selected softkey is assigned the new measurement version, in this
case, "Align plane".
the tool can be aligned perpendicularly to the plane.
workpiece parallel with the coordinate system
You stored the workpiece zero in a work offset that was not active
during measurement.
1. When you press the "Set WO" softkey, the activation window opens
asking whether you want to "Activate work offset Gxxx now?".
2. Press the "OK" softkey to activate the corrected work offset.
Rotating the workpiece coordinate system makes it necessary to realign
the tool to the plane.
The activation window asking whether you want to "Position measuring
probe perpendicular to plane?" is displayed.
1. Select "Yes" if you want to swivel into the plane.
The query "Positioning by swiveling! Retract?" is displayed.
2. Select the retraction method you want to use.
