This function does not support the look--ahead control function.
When a program contains G codes for starting chopping (G81.1) and
stopping chopping (G80), an attempt to restart that program results in a
P/S 5050 alarm being output.
When a program that does not include the chopping axis is restarted
during chopping, the coordinates and amount of travel set for the
chopping axis are not affected after the restart of the program.
G90 G81.1 Z100. Q--25. R10. F3000 ;
D Perform rapid traverse to position the tool to Z110. (point R).
D Then, perform reciprocating movement along the Z--axis between
Z100. (upper dead point) and Z75. (lower dead point) at 3000
mm/min. Chopping override is enabled.
