G G function
(preparatory function)
Only integer,
specified values
The G functions are divided into
G groups. Only one G function
of a group can be programmed
in a block.
A G function can be either
modal (until it is canceled by
another function of the same
group) or only effective for the
block in which it is programmed
(non-modal).
