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. 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
Compensation Q402: Define whether the TNC
should set the measured misalignment as basic
rotation or should align via rotating the rotary table:
0 : Set basic rotation
1 : Rotate the rotary table
If you specify rotating the rotary table, the TNC
does not save the measured misalignment, even if
you have defined a table row in parameter
Q305.
Set to zero after alignment Q337: Define whether
the TNC should set the display of the aligned rotary
axis to 0:
0 : Do not set the rotary axis display to 0 after
alignment
1 : Set the rotary axis display to 0 after alignment.
The TNC only sets the display to 0 if you have set
Q402=1.
