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
8
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.
8
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.
