Weighting of rapid traverse velocity (G129)

Syntax:

G129=..

Axis group-specific weighting of rapid traverse weighting for all axes in [%]

modal

The G129 functions can be used to change the rapid traverse velocity G00.

The feedrate can be influenced by a percentage change in the associated velocity characteristic value.

If programming takes place with G129, all axes which are not programmed or not yet programmed are set to 100%. Each further selection of these functions, irrespective of the previous programs, signifies 100%. This means, the geometrical data processing always weights the default value P-AXIS-00209 with the percentage value.

Therefore, 50% programmed twice in succession means the setting is made to 50% and not to 25%.

Notice

notice

Feed weighting only acts on rapid traverse NC blocks (G00). It has no effect on single axis motions e.g. homing, manual mode or independent axes.

Attention

attention

If G129 is >100%, rapid traverse velocity is limited to the MAX value P-AXIS-00212.

If G129 = 0, rapid traverse velocity is limited to the minimum value 1µm/s.

Programing Example

prg_example

Weighting of rapid traverse velocity (G129)

N10 G129 = 70

(Axis group-specific rapid traverse weighting)

(Rapid traverse velocity of all axes to 70%)

N20 G00 X100 Y150

(Linear interpolation, rapid traverse motion with 70%)

Special feature:

N50 G129 = 70 X10 Y20

(With G129 in the same block, axis positions)

(can also be programmed!
