MDV Segments
Segments are created using a sequence of MDV statements. The simplified syntax for the MDV (Move
Distance with Velocity) statement is:
MDV
<distance>,<velocity>
The <distance> is the length of the segment move. The <velocity> is the final velocity for the segment
move. The starting velocity is either zero or final velocity of the previous segment. The final segment in a
complete move must have a velocity of zero. If final segment has final velocity anything else then zero
motion stack underrun fault will occur.
The profile shown below can be broken up to 8 MDV moves. The first segment would define the distance
between point 1 and point 2 and the velocity at point 2. So, if the distance between point 1 and 2 was 3
units and the velocity at point 2 was 56 RPM, the command would be: MDV 3 , 56. The second segment
would give the distance between point 2 and 3 and the velocity at point 3, and so on. Any profile can be
programmed using MDV moves.
From the following table, write a program to execute the move profile shown, and run it.
