U
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
Alternatively PREDEF
U Default setting for basic rotation 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. The parameter has no effect if the
misalignment is to be compensated by a rotation of
the rotary table (Q402=1). In this case the
misalignment is not saved as an angular value. Input
range 0 to 2999
U Basic rotation / alignment Q402: Specify whether
the TNC should compensate misalignment with a
basic rotation, or by rotating the rotary table:
0: Set basic rotation
1: Rotate the rotary table
When you select rotary table, the TNC does not save
the measured misalignment, not even when you have
defined a table line in parameter Q305.
U Set to zero after alignment Q337: Definition of
whether the TNC should set the display of the aligned
rotary axis to zero:
0: Do not reset the display of the rotary axis to 0 after
alignment
1: Reset the display of the rotary axis to 0 after
alignment
The TNC sets the display to 0 only if you have defined
Q402=1.
