N10: The X-axis moves with velocity FX1000.00 to position X100.000.
N20: As soon as the X-axis has reached its PEH window, the Y-axis moves to position
Y100.000.
N30: When the Y-axis has reached its PEH window, it moves on to position Y300.000.
N40: When the Y-axis has reached its PEH window, the X and Y-axes move to positions
X300.000 and Y500.000. As the Y-axis reaches its destination earlier, it stops and
waits for the X-axis.
N50: When the two axes have reached their respective PEH window, they traverse to their
new positions X500.000 and Y700.000.
