1.10.3 Segment Moves

MOVED and MOVEP commands facilitate simple motion to be commanded, but if the required move profile is more
complex than a simple trapezoidal move, then the segment move MDV can be used.

The profile shown in Figure 11 is divided into 8 segments or 8 MDV moves. An MDV move (Move Distance Velocity) has
two arguments. The first argument is the distance moved in that segment. This distance is referenced from the motor’s
current position in User Units. The second argument is the desired target velocity for the end of the segment move. That
is the velocity at which the motor will run at the moment when the specified distance in this segment is completed.
