Good morning,
Ive a sunfar e550 vfd here,its a 1.5kw model, I wish to use the external switching and freq controll option by wiring in an external potentiometer and 2 way switch for directional control but im a bit stumped at what rating(this is where im not good) a potentiometer to use, my machines manual calls for 0-10 v (0-20 ma) maybe this can be worked out simply by a VIR calculation? I understood a pot was a kind of resistor which surely should be rated in ohms? im a bit special when it comes to electronics go easy on me! in any case I have two pots myself,one reads :min pot linear 470k the other reads min dual pot log 10k,can any of these be used on my vfd?
thanks for your time
