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 This was of course, not at all clear – and Steppwr emailed Arcus recommending that they includ some descriptive documentation with the. Message 2 of 4.

Any help would be much appreciated. Message 3 sepper 4. 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.

An input parameter is invalid. Most Active Hardware Boards: Motion Control and Motor Drives.
I can only test so far without the stepper motor but have made some progress. 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.

For example if the input is a path, the path might contain a character not allowed by the OS such as? I think the first part of the error you posted “An input parameter is invalid 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.
The principle problem came from trying to use demo. 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.
What was happening was that demo. 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.
Hope this helps Jack. I attach the final vi I made ‘motor control’ and the sub vi library, incase anyone working with the same hardware finds them usefull.
