2.2.2.2. Segment Load Window
Each profile segment type has an associated Segment Parameters window (label 2
in
. As you highlight a particular profile segment in your motion
profile, that segment’s parameter window becomes available for entering data.
The default profile segment type is an Index profile segment.

Description
Apply All Segments
Lets you apply the current profile segment load parameters to all existing profile segments.
The load values are not applied to any profile segments that are added after you apply this
feature. However, you can return to this window and click Apply All Segments again to
apply the load values to new profile segments.
External Force
This is the external force that exists for the selected profile segment.
Payload Mass
This is the payload mass that exists for the selected profile segment.
Mass X, Y & Z - Offset
These Load Mass Offsets generate moments that are used in the calculation of Life for
Bulletin MPAS stages. Moments are generated when the Load Mass is off-line with the
actuator. They arise as a consequence of forces generated by acceleration or deceleration of
the load mass and gravity acting on the load mass being multiplied by the offset distance.
The offsets and moments are resolved into the three cartesian coordinates.
The load can be divided into either a fixed load or a load that changes by segment
throughout the profile. Motion Analyzer software analyzes the sum of the fixed loads and
moments (entered in
) and segment wise loads and moments
generated by these offsets.
Payload Animation
Starts a simple animation that demonstrates a pick-and-place machine where a heavy load
is picked up and moved forward. The return stroke has no load. Refer to
