Hey Jim,
you want the Potentiometer to be enabled to choose speed.
As I don’t have this Huanyang VFD I do not know if the Pot on the Panel can be enabled with “0”. But you know that you can choose the speed by using “Arrow down” and “Arrow Up” on the Operator Panel?
Usually a Potentiometer is connected to the analog input, and thus this must be enabled. This would be “1” then for PD002. Did you try this?
