2.2.2.10.4. Index
An Index profile segment consists of an acceleration, a cruise, and a deceleration.
Figure 125 - Index Motion Parameters Dialog Box
Enter the following parameters for a Index profile segment, if relevant.
Table 95 - Index Properties
Parameters Description
Segment Name Enter a meaningful name for the profile segment.
Increment/Absolute
Select whether to input Incremental or Absolute parameter values. Incremental values
represent the change in either the distance or time that occurs during the profile segment.
Absolute values represent the total distance or time elapsed throughout the entire motion
profile.
Distance/Time Enter either the Distance or Time parameter to define your Cruise/Dwell profile segment.
Index Type
From the pull-down menu, choose one of the three available index types.
Automatic
1/3 acceleration, 1/3 coast, and 1/3 deceleration trapezoidal motion profile. This
is the default setting.
Triangular ½ acceleration and ½ deceleration motion profile.
Trapezoidal
This index type lets you use sliders to adjust the velocity and time axes of the
motion profile.
Vertical Bar: Adjusts the height/velocity component of the motion profile. As
you increase the value of this slider, more time is spent accelerating and
decelerating the load and less time is spent dwelling at a constant velocity.
Horizontal Bar: Adjusts the ratio of the time spent accelerating to the time
spent decelerating for the profile segment. A negative value on the slider
indicates that more time is spent decelerating the load than accelerating it. A
positive value on the slider indicates that more time is spent accelerating the
load than decelerating it.
