we have a powerflex 525 speed reference 1 set to 0-10 v input and speed reference 2 set to ethernet ip but when enabled in the program the drive still runs off the set speed of the potentiometer. We are wanting the main control source to be the pot but when a foot switch is pushed for the outfeed frequency to change to a preset speed we determine in the plc. The pot is wired directly to the drive.
