2.2 Program defaults for cycles
Overview
All Cycles 20 to 25, as well as all of those with numbers 200 or
higher, always use identical cycle parameters, such as the set-up
clearance
Q200, which you must enter for each cycle definition.
The
GLOBAL DEF function gives you the possibility of defining
these cycle parameters once at the beginning of the program,
so that they are effective globally for all fixed cycles used in the
program. In the respective fixed cycle you then simply link to the
value defined at the beginning of the program.
The following GLOBAL DEF functions are available:
