6) STEP operation (incremental movement)
This operation is for manual operation to move by increment from the current position. If the
input contact X1.0 is entered, then the X axis and Y axis move to a number in the L100 and
L101 respectively, and if the input contact X1.1 is entered, then the X axis and Y axis move
to a number in the L102 and L103 respectively. Set the execution movement velocity into L104.

ISTEP L102 L104
Æ
Set the L102 to the X axis setting value, the L103 to the Y axis
setting value, and the velocity to the L104 setting value.
