Labview based Velocity control linear translation stage XPS Q8

[Ashgator001]

Hello all!

I am currently trying to setup a labview based automation for an XPS Q8 motion control, as a part of a project. What I used to do earlier was logged in to the browser based control for XPS and initialized the linear stage setting the velocity via the browser itself, and then used the VIs for controlling my motion. I required only single axis linear stage motion, and the absolute motion, relative motion VIs 

Now, I am trying to automate it all using LabVIEW starting from login to linear stage motion.

I have been successful in all the steps except in controlling the velocity of linear stage motion.

I am unable to obtain any VI 'exclusively' for velocity control. I have been trying to work around this with using VIs that have a cluster of setting various functionalities one of which is velocity. I set velocity to my desired value leaving the other values zero, but the VI's get executed only till the GroupHomeSearch and then error is displayed and the program stops.

It would be highly helpful if anyone can please help me find a way to control the velocity with LabVIEW.

I have attached the images of the related VIs. 

Thanks

So, I just wanted to add something to the question.

I tried to replicate the program, but using the web based control for the Motion Controller this time. So, I tried initializing through web and then ran the program for S gamma parameters, then the same error again popped up. So, now I think that, the error may lie somewhere in the way I've done the connections. I have attached the picture. of the VI used.

Is there any way to work around this, so that I can still get to my end result of complete automation of the setup, with velocity control?

The "SGamma Parameters" bloc is used for example with PosSgammaParGet ou PosSgammaParSet. In this vi, you can change the speed of the positioner.
