Weighting of rapid traverse velocity (G129)

G129 = <expr> (modal)

G129 Axis group-specific weighting of rapid traverse

<expr> Weighting in percent for all axes

With the functions G129 it is possible to alter the rapid traverse velocity G00.

An influencing of this rapid traverse velocity is achieved by parentally changing the appropriate velocity-characteristic value.

In programming with G129, all non-programmed or not yet programmed axes are set to 100%. Each further selection of this function, irrespective of the previous programs, signifies 100%. That means, the geometrical data processing always weights the default values [2]-25 with the percentage value.

If 50% is programmed twice successively, then this means that the setting is done at 50% and not at 25%.

The feed weighting works only for rapid traverse NC blocks (G00). It does not work for single axis slopes e.g like homing, manual mode, or independent axes.

Programming example

N10 G129 = 70 (Axis group-specific rapid traverse weighting) 
(Rapid traverse velocity of all axes to 70%)) 
N20 G00 X100 Y150 (Linear interp., rapid traverse movement with 70%) 

Special feature:

N50 G129 = 70 X10 Y20 (In the same block with G129 also axis)
(positions can be programmed)
