Weighting of maximum velocity (G127/ G128)
Syntax: | ||
G127 <axis_name>.. | Axis-specific weighting of maximum velocity: weighting for specific axes in [%] [as of V2.11.2808.14] | modal |
G128=.. | Axis group-specific weighting of maximum velocity. Weighting for all axes in [%]. | modal |
Using the G127/G128 function it is possible to change the maximum velocity.
The maximum velocity can be influenced by a percentage change in the associated velocity characteristic value.
If programming takes place with G127/G128, all axes which are not programmed or not yet programmed are set to 100%. Each further selection of this function, irrespective of the previous programs, signifies 100%. This means, the geometrical data processing always weights the default value P-AXIS-00212 with the percentage value.
Therefore, 50% programmed twice in succession means the setting is made to 50% and not to 25%.
 | Feed weighting at maximum velocity does not act on single axis motions e.g. homing, manual mode or independent axes. |
Notice | |
If G127/G128 > 100% the maximum velocity is limited to the MAX value P-AXIS-00212. If G127/ G128 = 0, the maximum velocity is limited to the minimum value 1µm/s. |
Programming Example
Weighting of maximum velocity (G127/ G128)
N10 G127 X70 Y60 | ;Axis-specific weighting of vb_max ;vb_max of X axis is restricted to 70% ;vb_max of Y axis is restricted to 60% |
N20 G128 = 100 | ;Axis group-specific weighting of vb_max ;vb_max of all axes to 100% |
Special feature: | |
N20 G128 = 100 X10 Y20 | ;Using G128, axis positions ; can also be programmed within the same block! |
