How to interact Motor Controller with Load cell via LabVIEW

[Kindly-Wisher]

Dear all,

I am kindly asking you for help to programming my Test setup which is indicated below:

I have a loadcell, motor and a motor controller, i have all the motor controller labview drivers!

The question is: i dont know how to use these labview drivers and how to interact the motor controller with the loadcell.

Please have a look at the summary of the working principle for this setup below:

While the linear stage  is running on a single axis via the motor controller ,  the linear stage touches the loadcell and  it is starting to make compression on load cell and after a specific, predefined Force, (for example 10 Newton) on the loadcell, i want to stop the motor so it does not go further, and then start to moving the linear stage at the negative direction now it will make a tensile strength on the load cell then again i will want to stop the motor controller when the loadcell reaches the predefined force (for example 10 Newton)

I read all the data sheets but it is not indicated that how to use these labview drivers, For example: How to turn the load cell’s output to an input to the motor controller? should i use “acceleration”and “set velocity” drivers next to each other? How to connect them? Doyou know any similar or exact codes? Which product should i use? (SignalExpress? Regular Labview? Control&Simulation? etc..) 

Please have a look at my brand new equipments below:

Motor Controller= Newport SMC100CC Single-axis DC motor controller/driver

Motor Linear Stage= Newport MFA-CC Miniature Linear Stage DC motor

DAQ= NI USB-6343, X Series Data Acquisition

Loadcell = Transducer Techniques, GSO-100 (Tension&Compression)

Loadcell Signal Conditioner = Transducer Techniques STAND ALONE / BENCH TOP, 0 to ±10VDC OUTPUT

Thank you for reading,

Have a nice day,

Best Regards,

Kindly wisher.

Hi there.

When you say you have the LabVIEW motor controller drivers, do you mean you have downloaded NI-Motion? (https://www.ni.com/en/support/downloads/drivers/download.ni-motion.html)

If so, how are you hooking the Newport motor controller to your computer?

The NI-Motion VIs and drivers are designed specifically to work with NI's motion controllers. If you're trying to control the motor with our USB-6343, you might have to design very low-level operations built yourself from the ground up.

Dear ravi.antavi

Regarding the motor controller's labview drivers, I mean these documents: ftp://download.newport.com/MotionControl/Current/MotionControllers/SMC100/Software/ 

Do anybody have any idea how to coordinate the motor controller while taking care of the loadcell resuls? Is that so hard? !!

Best regards.

You could look into triggering or event structures. This way, when you reach a certain number, you can have another piece of code in LabVIEW execute.
