Basic Customer Adjustments
Maximum Speed (MAX SPD)
The MAX SPD pot sets the maximum motor speed (80-120% of motor base
speed) allowed. It is factory preset to the midway position. Note: Do not exceed
motor nameplate maximum speed rating. With the motor running, turn the speed
pot on the drive enclosure cover/operator control panel fully clockwise while
monitoring actual motor RPM or by measuring the Armature Voltage on A+ & A-.
Then, adjust the MAX SPD pot on the control board to set the desired maximum
motor speed. Do not exceed the motors Armature Voltage nameplate rating.
Minimum Speed (MIN SPD)
The MIN SPD pot sets the minimum speed (0-30% of maximum speed
setting) at which the motor will run. It is factory preset at its full counterclockwise
position. With the motor running, turn the speed pot on the drive enclosure
cover/operator control panel fully counterclockwise. Adjust the MIN SPD pot
clockwise until the desired lowest motor speed is reached.
