lang stepping motor VI's

[Theone2222]

Hello all,

I am working with Lang MCL 2 stepping motor that controls a table with X and Z axes. What is the best way to assign a reference point (0,0)?! And what VI's do u recommend to do that?

Best Regards,

Hello Theone2222,

could you please explain your application more exactly.

Which NI-Software are you using? What do you mean with "And what VI´s do u recommend to do that?"? Are you looking for a special VI, with that you can assign a reference point?

I am using labview 8.5. And with the special VI's I mean prepared VI's that could be downloaded and specify the whole movement of the table from reference point to move a step on Y or X directions and so on.
My goal is to define a reference point, from which I can start more complicated movements and after finishing go back to that reference point.

Hello Theone222,

in which way is your stepping motor connected to your computer?  Are you using NI hardware?

If you are using NI hardware you can download the NI-Motion tool for your LabVIEW version. After that you can buy a license for your motion tool.

HI Nina,

No I am using Lang MCL 2 stepping motor connected to the computer through RS 232. I am using lab view 8.5 to control it. the motor is connected to a table with X-Y axes. I want to set a reference point for the table and then try to excute a set of more complicated movements and then back to the reference points. I already have a set of labview sub VI's (blue color) and I want to know if there is another pr better VI's to use. or how to use those I already have (if there is some kind of documentation for them) cos I searched and couldn't find any.

Hi Seno,

do you know, where you have these VI´s from? Where they in the package of your stepping motor (so you got them from the manufactorer of the stepping motor), have you downloaded them from the NI developer zone or are these VI´s in the LabVIEW version you´ve bought? Could you please tell me, what the names of these VI´s are?

If you have VI´s from NI itself you can also have a look on the help topics. If you klick on help there is also a topic called "searching for examples". Have you already tried to do this?

Hi Nina,

No they are not from the motor company nor from NI. some one where I wrok downloaded them from the developer zone I guess. the package is called LANG and they are a bunch of blue coded VI's.

This is a pic of the VI's I am talking about. hope it can help a little.

Hi Theone222,

sorry, but these VI´s are not from NI. I searched on the Internet for these VI´s, but couldn´t find anything useful for you.

Maybe, it´s the best, you contact the producer of your stepping motor (if these VI´s are from him). If they aren´s from the producer, he will maybe have some VI´s for your stepping motor.

In my opinion, it would be the best, you take a reference point (0/0). Take the smallest possible point on x-axes and the smallest possible point on y-axes,

so you have only one possibility to start in in x-direction and one possibility to start in y-direction.

Hope this was useful.

Best Regards
