N10:
The X-axis moves in absolute dimension G90 at path velocity F2000.00 to position
X10.000.
N20:
The Y-axis moves in absolute dimension G90 at path velocity F2000.00 to position
Y20.000.
N30:
The X and Y-axes move in incremental dimension G91 to position X10.000/Y10.000.
As the two axes have to traverse the same distance, they move at the same axis
velocities.
N40:
The X and Y-axes move in absolute dimension G90 to position X40.000/Y40.000. The
X-axis has to traverse a longer distance, it traverses at a higher axis velocity than the
Y-axis.
In this example, "exact stop G60" is assumed to be the block transition
behaviour. In the chapter "block transitions", the different possibilities of
block transition are described in detail.
The programmed axis velocities refer to 100% override. Lower or higher
override values are taken into account in the axis velocities.
