2.6.6 The G-Functions
A G-function can follow an N-function. It is identified by the letter 'G', followed by a two digit num-
ber. Only one G-function is permitted in a statement. Only the following G-functions are per-
mitted:
G04: dwell time
G1 O: flying change
G20: loop end
G24: loop start
G26: approach target in clockwise direction (*)
G27: approach target in anti-clockwise direction (*)
G40: clear tool length offset
G43: positive tool length offset on
G44: negative tool length offset on
G53: clear offsets
G54: offset 1 on
G55: offset 2 on
G56: offset 3 on
G57: offset 4 on
G74: reference point approach
G91: position specifications incremental (*)
At the beginning of a program the following G-functions are automatically active:
If the machine data of the axis on which the machining program is to be executed are in mm,
mensions in 0.1 inches) is the default.
If degrees are selected, neither G70 nor G71 are defaults, since it is not possible to change the di-
mensional unit.
With the G-functions implemented on the IP247, the following preparatory conditions, offsets or
switchovers can be executed.
2.6.6.1
The target position programmed in this statement is approached at the maximum speed (see ma-
chine data). Specifying the speed using the F-function is then not permitted.
