How to measure a following error with Flexmotion

Hallo!

I'm using the contouring mode of the flexmotion to write my defined
structures. I create the corresponding points which my motors have
to reach at specific times and load them into Labview. After the writing
experiments I want to be able to compare the defined and the written
structures. If you use the MAX you have an indicator for the following
error. Is it possible to read the following error from Labview, so that
I can store it in a file?

What I'm doing now, is that I read the encoder position every 10 ms
(Wait until next 10ms). The defined structure has also the points every
10ms. Unfortunatly Labview isn't reading the encoder every exeact 10s, so
that I can't compare this two vectors easily. You can still
make it
visually, but I would prefer a numeric solution.

Frank,

I think the VI you're looking for is called Read Following Error.flx. It can be found in the Trajectory Control pallette of FlexMotion.

Please let me know if you have any questions.
