Any help would be much appreciated. What was happening was that demo. If you do still get an error please can you update me with a screen shot of the error message and tell me what version of LabVIEW you are using and which OS you have so I can continue to troubleshoot. To solve this or rule out the possible error please try the following steps. I’m basing my program on the example which Arcus provide on their website, and which I attach in an llb the program is demo.

I attach the final vi I made ‘motor control’ and the sub vi library, incase anyone working with the same hardware finds them steppwr. W Applications Engineer National Instruments. Most Active Hardware Boards: I’ve been working on other projects for a while, but now that I come back to the stepper motor control I’m still at an impasse. The principle problem came from trying to use steppre.
Thanks very much for your help. Motion Control and Motor Drives: Can anyone help me with this?
I’ve managed to complete the VI now, working as was intended. Any help would be much appreciated. Message 3 of 4.
I can only test so far without the stepper motor but have made some progress. This was of course, not at all clear – and I’ve emailed Arcus recommending that they includ arcue descriptive documentation with the.

The problem I’m having is that when running the demo, having input some arbitrary positions for the motor to turn to, it returns error I’m basing my program on the example which Arcus provide on their website, and which I attach in an llb the program is demo. If you do still get an error please can you update me with a screen shot of the error message and tell me what version of LabVIEW you are using and which OS you have so I can continue to troubleshoot.
The error is confusing because the control mechanism does not use GPIB hardware or commands, also the VI was made by Arcus and I would have expected them to handle the formatting of the data inputs correctly.
What was happening was that demo. I think the first part of the error you posted “An input parameter is invalid I downloaded the drivers including the Dynamic-Link Library dll that go with the motor you have and at first couldn’t execute the VI.
To solve this or rule out the possible error please try the following steps. For example if the input is a path, the path might contain a character not allowed by the OS such as? Hope this helps Jack.

Message 1 of 4. The motor also comes with a piece of standalone software for controlling it, and this program works fine – which implies that there is no problem with the hardware or connection. Message 4 of 4. I’ve looked into the problem you describe.
