Spindle status: Q110
The value of Q110 depends on which M function was last
programmed for the spindle:
Coolant supply: Q111
Overlap factor: Q112
The TNC assigns Q112 the overlap factor during pocket milling
(MP7430).
Unit of measurement for dimensions in the
program: Q113
During nesting the PGM CALL, the value of the parameter Q113
depends on the dimensional data of the program from which the other
programs are called.
Tool length: Q114
The current value for the tool length is assigned to Q114.
