Tim I can't thank you enough for all your videos! They are absolutely excellent! You deserve the best!

[@TimWilborne]

Glad you like them Christos!

Tim. could you post an application using the analog input on the 1763- controller? Thanks

[@TimWilborne]

Sure thing, see the following link. www.theautomationstore.com/rslogix-500-lessons-on-analog-math-instructions-and-dealing-with-plc-faults/

Tim - you mention you have to tie the common of the drive (10V) to common of the trainer PS (24V) - Can you explain why you have to tie both? Please elaborate further .

[@TimWilborne]

This probably warrants its own video but if you don't, they won't have the same reference point so you won't get a true reading when sending a signal from one to the other.

Tim, could you add a schematic of the wiring with your video please? Can’t wait for the analog video.

@@TimWilborne That schematic does show how it was wired to the VFD. No matter how I wire it, it either shows .1 volt or 23.9v, and if I turn the dial all the way to the left, it shuts off the 24v power supply. Weird.

[@TimWilborne]

@@toolboy3555 It sounds like you're shorting the + and - of your power supply with potentiometer so that the further you turn it up the more amps is pulling. Can you describe a little more about how you have a connected?

how to choose the potentiometer Value

[@TimWilborne]

Usually it will be speced by the device you are connecting to.
