Inverter external potentiometer connection

Potentiometer is a resistance element with three lead ends and its resistance value can be adjusted according to a certain law. Potentiometers usually consist of a resistance body and a removable brush. When the brush moves along the resistance body, the resistance value or voltage which is related to the displacement is obtained at the output end.

First of all, the connection between the inverter and the external potentiometer should be recommended to use the shielded wire, in the distance between the inverter and the external potentiometer is best not to recommend more than 2 meters, more than 2 meters to consider the quality of the shielded wire, the thickness between the line diameter can not be small. The voltage drop of the inverter can be ignored, if the voltage drop is too large, can be used to use a single core of copper wire shielding voice shielding line. Then the analog output of the inverter is set as the operating frequency, and then the regulator can be converted into a 4-20ma signal and sent to the signal input terminal of the inverter, so as to achieve the purpose of controlling the frequency conversion. At this time, the frequency setting of the inverter can be set by an external frequency potentiometer. Finally, the sliding end of the external potentiometer is connected to the inverter voltage input AVI, and the other ends are connected to +10V and the common end.

Another theory potentiometer can also control two inverter at the same time, but in order to reduce operating errors, it is best to use two way digital signal to the potentiometer to control the output current, first of all set a current value (or the inverter frequency values) for potentiometer corresponding output current value of the same, in order to achieve the goal of control both frequency converter. At this time the inverter is best changed to the current signal control.
