N10: The X-axis moves with velocity FX1000.00 to position X100.000.
N20: In the braking point of the X-axis, the Y-axis is started and moves with velocity
FY1000.00 in the direction of position Y100.000.
N30: At the braking point, the Y-axis accelerates to its new velocity FY2000.00.
N40: While the Y-axis approaches the new position Y385.000 without speed reduction, the
X-axis is started. As this axis needs more time to reach its point of destination, the Y-
axis starts to brake.
N50: The X and Y-axes accelerate to their respective velocities. As the Y-axis reaches its
destination earlier, it stops in its position and waits until the X-axis has reached its
braking point.
N60: At the braking point of the X-axis, the Y-axis accelerates again. The two axes move
up to their destinations and stop.
