If I'm using one input to ramp up a motor through each step, and I want the motor to ramp up as long as that input is active BUT if the input is inactive I want to go backwards one step at a time, how do I do that? Currently What's happening is when the input goes inactive, it will go back one step and get stuck unless I flag the input again. We're trying to do this without a PLC by the way.

After reading your comment, it seems you have already answered you question. Regarding what you said, Check you wiring & open CCW then verify the parameters are correct. If you need just a few different speeds then I would just set up a few different speeds in the VFD & wire the inputs to the VFD to change speeds, meaning, do not use step change. Use the standard speed control inputs

@@ShaneWelcher Thanks for the quick reply! I actually figured it out shortly after. Instead of having the OR statements revert back to previous steps, I had them skip forward to a different step. Somehow going backwards was getting the logic stuck. It's really hard to explain the problem without showing the logic but hey it works!
