LabVIEW
sinusoidale motion using XPS Controller NEWPORT
Hi Sidali,
I think that to change position sinusoidally as a function off time, you'll be wanting to vary velocity sinusoidally (perhaps "cosinusoidally" 
) as a function of time.
Use the XPS Jog mode to change the stage's velocity while stage is moving.
Of course you'll want to keep velocities within stage-limits.
In order to have more direct control over position while changing velocity, you could have a loop rapidly poll position and set velocity based on position. That way you could easily shift the middle of sinusoidal motion.
Hope it helps!
Hi sidali,
I'm sorry but don't have the hour(s) it would take to generate an example for you.
If by "screen about your solution" you mean a screen-shot of my existing code, it would be impractical to share; you'd need many screen-shots to see all the relavant pieces. What I have is (much) more complicated than what you need.
.
... but you should be able to get something working! 
Build this project "incrementally", start by building a VI that follows "Jogging" example-flowchart in XPS Programmers Manual:
1) Opens connection
2) Kill Group
3) Initalize Group
4) Home Group
5) Enable Jog Mode
6) Change velocity "GroupJogParametersSet"
7) Wait ms
😎 Change velocity "GroupJogParametersSet"
9) Wait ms
10) Change velocity "GroupJogParametersSet"
11) Wait ms
12) DIsable Jog Mode
13) Close TCP Connection
Next, modify this VI to execute a For Loop after "Enable Jog Mode"
In the ForLoop, send each velocity from an array of velocities (you assign velocities to achieve sinusoid).
Disable/Close after For Loop.
Next, modify the VI to execute a while loop after "Enable Jog Mode"
In the while loop, read position and set velocity according to position.
Wire a "Quit" boolean/button to the While-loop "Condition" terminal.
Cheers!
