Stepper Motor Control, oscilator, with pauses

[GordonH]

I would like a vi that controls a 1-axis stepper motor to oscilate with different pause times at each extreme of motion. I'm using Labview 7 with a PCI-7341 board, a UMI-7764 universal connector, and a RMS R701 Step Drive. I have established communication with the stepper motor and can use the automation explorer and the sample vi's that came with Motion. But I don't have the experience to modify the sample vi's to do what I want.

Take a look at the following example program:

This creates a sinusoidal motion. All you will need to do is input the sine wave positions you want and then add a Wait VI at the extremes for however long the required pause time is.

If you need more help programming, you may want to consider either speaking with an Alliance member to assist you or taking a LabVIEW programming course.
