usb 6008 digital signal wave output

[sylvosdono]

Hi All,

I am working on a project where I am powering a digital servo (http://www.hobbypartz.com/servo-mg946r.html) to move a 0.5 kg test weight via the attached VI that I found on the boards.I am using LabView 7. I know that it requires a digital square wave to operate, but I am not sure how to improve this file and am not well-versed enough in programming logic to develop a new one. I can hear the gears trying to turn inside my servo at the 100 Hz setting, but not enough to get it to move - any suggestions?

Thanks,

Le

This is sounding like an issue with current.  I wasn't able to find a control current requirement for your servo, but I'm guessing it needs more than the 6008 can put out of its DIO.  You need a buffer chip that can supply more current.

Got it, I will try that out next. Thanks!
