MIN: Minimum Speed
The MIN trim pot is used to set the minimum output frequency of the drive, which sets the minimum motor speed. The minimum speed is factory set to 10 Hz. Readjust the trim pot as follows:
1.Rotate main speed potentiometer to the
minimum speed position (full counterclockwise).
2.Increase setting of MIN trim pot so that motor runs at desired minimum speed.
