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
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).
G0 Linear interpolation with rapid traverse

G1 Linear interpolation with feed
G2 Circular interpolation clockwise
G3 Circular interpolation counterclockwise
G4 Predefined dwell time
G9 Exact stop deceleration

G17 Selection of working plane X/Y
G18 Selection of working plane Z/X
G19 Selection of working plane Y/Z
G25 Lower working area limitation
