9.4 Rapid traverse movement (G0, RTLION, RTLIOF)
Linear interpolation applies in the following cases:
● For a G-code combination with
● For a combination of
● When the compressor is active
● When a transformation is active
Example:
Program code
G0 X0 Y10
G0 G40 X20 Y20
G0 G95 X100 Z100 M3 S100
Path POS[X]=0 POS[Y]=10 is traversed in path mode. No revolutional feedrate is active if
path POS[X]=100 POS[Z]=100 is traversed.
Settable block change time with G0
For single-axis interpolation, a new end-of-motion criterion
be set for block change even within the braking ramp.
Consecutive axes are handled in G0 like positioning axes.
With the combination of
● "Block change settable in the braking ramp of the single axis interpolation" and
● "Traversing path axes in rapid traverse movement as positioning axes with G0"
all axes can travel to their end point independently of one another. In this way, two
sequentially programmed X and Z axes are treated like positioning axes in conjunction
with G0.
The block change to axis Z can be initiated by axis X as a function of the braking ramp time
setting (100-0%). Axis Z starts to move while axis X is still in motion. Both axes approach
their end point independently of one another.
