Using GLOBAL DEF information

If you have entered the corresponding GLOBAL DEF functions at
the beginning of the program, then you can link to these globally
valid values when defining any fixed cycle.

Proceed as follows:

Select the Programming and Editing operating
mode

Select fixed cycles

Select the desired group of cycles, for example:
drilling cycles

Select the desired cycle, e.g.

DRILLING

The TNC displays the SET STANDARD VALUES
soft key, if there is a global parameter for it

Press the SET STANDARD VALUES soft key. The
TNC enters the word

PREDEF (predefined) in the

cycle definition. You have now created a link to the
corresponding

GLOBAL DEF parameter that you

defined at the beginning of the program

Danger of collision!

Please note that later changes to the program
settings affect the entire machining program, and
can therefore change the machining procedure
significantly.

If you enter a fixed value in a fixed cycle, then this
value will not be changed by the

GLOBAL DEF

functions.
