MotionDesigner Reference & User Interface > Data-Transfer Table

Overlay-Trace (in Orange)

You can plot the data that is in the Data-Transfer Table as a dumb graph, together with an existing motion.

We call this dumb graph an Overlay-Trace.

It is not possible to edit the Overlay-Trace.

We use an Overlay-Trace to compare the data that is in the Data-Transfer Table with the motion that you can edit.

E.G. : It is often useful to get the motion-data from a different motion, and to show it as an Overlay-Trace in the active motion.

To show an Overlay-Trace

1.Make sure there is data in the Data-Transfer Table (see Prepare the Data, below)

2.Click the Overlay-Trace icon

The plot of the data will show as the Overlay-Trace together with the active motion.

3.Click in the graph. The active-motion and the Overlay-Trace will rescale to their maximum and minimum values.

To hide the Overlay-Trace:

1.Click the Overlay-Trace icon again

The plot is removed.

Prepare the Data.

You must have at least 5 data points

The data should be in the Data-Transfer Table, as follows:

•The Position data should in Columns 2 and start at Row 0.

If these data are available:

•Velocity, Acceleration, and Jerk data should be in Columns 3, 4, and 5, respectively, al starting at Row 0.

Overlay-Trace: a simple example:

E.G.: To show the motion-values of Motion0 as an Overlay Trace in Motion1

If necessary:

1.Click File toolbar > Add Motion to add a Motion1 as a new motion name-tab

2.Click View toolbar > P, V, A, J buttons to show all motion-derivatives

3.Click Motion0 name-tab to make it the active motion

4.Click View toolbar > P, V, A, J buttons to show all motion-derivatives

Open the Data-Transfer Table:

We want to get data that represents Motion0 into the Data-Transfer Table

The Data-Transfer Table will fill with the motion-values of each graph that is in Motion0

Make Motion1 the active motion.

7.Click Motion1 name-tab to make it the active motion

Now you can show the data that is in the Data-Transfer Table as the Overlay-Trace in Motion1

8.Click Data-Transfer Table > Overlay Trace button

You will see the motion-values of Motion0 as an Overlay Trace in Motion1.

9.Click in the Graph of Motion1 to show the full scale of Motion1 and the Overlay Trace.
