Simple stepper motion control

Hello all, I am completely new to motion control and my head is spinning with all the options so please bear with me, all help is much appreciated.

 

I am trying to build a control which will perform point to point movement of something like this:

http://www.haydonkerk.com/LinearActuatorProducts/StepperMotorLinearActuators/LinearActuatorsHybrid/S...

 

It will be moving to a specified point and then returning to the "home" position, holding and then repeating for a number of cycles. The timing of the movement needs to be pretty accurate, each movement cycle will last about 2 tenths of a second. There will be a few parameters that the user should be able to select before beginning the test.

 

I think I will need to execute this in real time and I am really hoping to do the programming in Labview for no other reason than I like it better than text based. So my question is really what hardware and software am I going to need to get this done? I went through the info on NI's website and due to my lack of background knowledge it was pretty confusing. It looks like as far as software goes it will basically be Real-Time module. For hardware it looks like a controller and a driver. If I had the PXI-7332 controller and the P70530 driver am I good to go? Or am I missing some critical aspect

 

Also, if any has any good recommendations for some reading on these sorts of things I would be interested in that as well.

 

Thanks.

Hi Nick,

 

We've got two basic options for motion control- PC based, or RIO based.  These types of questions are actually quite common for support, if you'd like to contact NI. If not, post back and I'd be happy to help.

Hi

 

You can use the driver  from www.robotservice.se to control directly from Labview via USB if you wan't or through a USB DAQ card with step/dir command, with the already labview .dll you can control with direct command ABSTARGET to move exactly the movement you wan't.
