Potentiometer Wiring
The picture below shows a VFD speed control potentiometer wiring with VFD internal 12VDC power
source. The recommended potentiometer parameters: Resistance from
1k to 10k; Wattage 0.5W or higher. The multi-turn potentiometer
provides more precise speed adjustment compare to a single-turn
potentiometer. The internal power supply provides 12VDC and in order
to have full range of speed control by potentiometer, change the I/O-04
parameter from 10VDC to 12VDC.
