velocity profile in a grafic of LabView

[diego77]

Hello
I wanto do a trapeze of velocity in a grafic of LabView. I will control a servo motor and it need a acceleration, after a constant speed and finally a desaceleración.

I want see and control this trapeze from the grafic, giving clik on the trapeze and moving the lines. After pass this data to a numeric indicators.

thank you very much for your help.

Hi,

here is a small VI which create a trapeze on a XY graph. You can move the trapeze by moving the points on it (click and drag)

i hope it will help

Hello, thank you for your answer.
please send me it in 2011 version.

I think that this vi can help me very much.

Hello, thank you for your help.

I am not using hardware now. I only want do a gráfic like the image attached, and use this grafic like a control, moving the lines in the grafic, after show the aceleration, velocity constant and deceleration in numeric indicators.

thank you

Here it is!

I´m sorry, I can´t open it.

[GiulianoFranchetto]

? that's strange.Try with this one

[diego77]

that´s excellent, thank you very much.

Only a question more.

How I can restrict the movement of the second and third cursor to have always the same value of y?

if i move the second cursor, the third takes the same value of y, and the same with the third.

So that the second and third courses always be on the same horizontal line.

thank you for your help.
