Timed Motor Control /w LabJack

[Dominj]

I'm new to Labview and this is what I'm trying to accomplish: I want the user to press a start button, then a motor will go at full power for a set amount of time (maybe 5 or 10 seconds) then that motor will stop and the rest of the program will continue. I think I have the necessary items to accopmlish this (button, analog output, while loop, time delay) but I don't know how to connect them to make it work. Any help would be appreciated.

Hello,

Is LabJack the only hardware that you are using to control this system? Are you using any form of motion control software or hardware (i.e. a PCI 7344 motion control board or something similar)? How are you planning to control the motor? What type of motor/drive are you using for this system? Is it a stepper motor or a servo motor?

If you are not using any National Instruments motion control hardware and software, then you will have to devise your own algorithm to control your motor. Do you know the kinds of voltages and currents that will be required to connect to the motor or the drive? Are you using any kind of feedback from the motor?

I would suggest taking a look at the following webpages for information about how to control your motor:
