Resulting starting position: Contains the
calculated starting position of the
segment. For absolute segments, it
equals the specified start position. For
relative segments, it is calculated from
the preceding segments.
Minimum speed: Contains the calculated
minimum speed that occurs inside the
segment.
Maximum speed: Contains the
calculated maximum speed that occurs
inside the segment.
Minimum acceleration: Contains the
calculated minimum acceleration that
occurs inside the segment.
Maximum acceleration: Contains the
calculated maximum acceleration that
occurs inside the segment.
Type: Defines if the segment is executed
at an absolute slave position or relative
to the previous position.
Start position: Specifies the axis position
at the beginning of the segment.
Describes the position at gear in (=
motor side). If the segment type is
relative, the start position attribute only
modifies the logical CAM position. In
relative segments, the property can be
left blank (unspecified). If the start
position is not specified in a relative
segment, the logical CAM position from
the previous segment is used as starting
position.
End position: Specifies the axis position
at the end of the segment. When
changing this property, the value of the
Distance property is automatically
recalculated.
Distance: Specifies the distance between
the start and end axis positions
(meaning the angle to turn). Negative
distance values define backward
movements. When changing this
property, the value of the End position
property is automatically recalculated.
Start acceleration: Specifies the
acceleration of the axis at the beginning
of the segment. The acceleration is

Information (all read-only)
-
When the position of the Preceding node or Succeeding
node of a Guide poly is changed (graphically or
numerically), the Guide poly is automatically recalculated
and redrawn.
When any of the Guide poly properties are changed by
using the Property Window, the Guide poly is automatically
recalculated and redrawn.
It is possible to edit start position and end position of the
Guide poly graphically by selecting it and then using
vertical dragging as shown in Illustration 5.73.
calculated as a ratio between the axis

and the guide value (rev/rev
terized jumps may occur in the
acceleration when 2 succeeding
segments have different End acceleration
and Start acceleration values.
Start velocity: Specifies the velocity of
the axis at the beginning of the
segment. The velocity is calculated as a
ratio between the axis and the guide
value (rev/rev). The velocities of all
segments that are connected by the
same node should be the same to
ensure smooth movement. Incorrect
parameterization results in a jump in
velocity.
End acceleration: Specifies the
acceleration at the end of the segment.
For more information, see Start
acceleration.
End velocity: Specifies the velocity at
the end of the segment. For more
information, see Start velocity.
Polynomial order: Contains the
polynomial order that results from the
specified start and end point, start and
end velocity, and start and end
acceleration.
