G functions
G G function (preparatory function)
G functions are divided into G groups.
Only one of the G functions in a group
may be programmed in a block.
A G function can be modally active (until
it is cancelled by another function in the
same group) or it is active only in the
block in which it is programmed (non-
modal).
Integer,
preset
