Traversing to clearance height Q301: definition
of how the touch probe is to move between the
measuring points:
0 : Move at measuring height between measuring
points
1 : Move at clearance height between measuring
points
Preset value for rotation angle Q307 (absolute):
If the misalignment is to be measured against a
straight line other than the reference axis, enter
the angle of this reference line. The TNC will
then calculate the difference between the value
measured and the angle of the reference line for the
basic rotation. Input range -360.000 to 360.000
Preset number in table Q305: Enter the preset
number in the table in which the TNC is to save the
determined basic rotation. If you enter Q305=0,
the TNC automatically places the determined basic
rotation in the ROT menu of the Manual Operation
mode. Input range 0 to 2999
