Hi! At present my Emerson VFD speed setting and start/stop is controlled on the unit itself. I want to revise the electrical control so that the speed can be controlled with an external potentiometer and a start/stop push buttons. I learned on the manual that the setting of parameter #05 must be changed from PAD to A1A2. I had already changed the parameter but Im having difficulty on the terminal numbers to be use for the potentiometer and the start/stop controls. Any suggestions please...
