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
U
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
U
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
