21. AXIS CONTROL FUNCTIONS
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.
