Various modes (Q406)
Test mode Q406 = 0
The TNC measures the rotary axes in the positions defined and
calculates the static accuracy of the tilting transformation.
The TNC records the results of a possible position optimization
but does not make any adjustments.
Position Optimization mode Q406 = 1
The TNC measures the rotary axes in the positions defined and
calculates the static accuracy of the tilting transformation.
During this, the TNC tries to change the position of the rotary axis
in the kinematics model in order to achieve higher accuracy.
The machine data is adjusted automatically.
Example: Position optimization of the rotary axes
with preceding, automatic datum setting and
measurement of the rotary axis backlash
