WebYou're trying to draw maybe half an amp, maybe just 100ma, through one section of your potentiometer. First off-- if you want to draw that much current, 10k of resistance is massively too high. No more than 50 ohms would be needed to vary the speed from full to practically 0 when you're dealing with the kind of current a fan needs. Web(Motor electric constant needs tuning: Offline tuning) ;*1 to * 3 and *6 : Automatic deceleration ・If the DC link bus voltage or calculated torque exceeds the automatic deceleration level during deceleration, the inverter automatically prolongs the deceleration time to avoid overvoltage trip.
