Calibration
MINIMUM SPEED (MIN SPD)
The MIN SPD setting determines the motor speed when the speed adjust potentiome-
ter or input signal is set for minimum speed. It is factory set to zero speed.
To calibrate MIN SPD:
1. Turn the speed adjust potentiometer full CCW or set the input signal for minimum
voltage or current.
2. Adjust the MIN SPD trimpot until the motor has stopped, or is running at the
desired minimum speed.
MAXIMUM SPEED (MAX SPD)
The MAX SPD setting determines the motor speed when the speed adjust potentiome-
ter or input signal is set for maximum speed. It is factory set for maximum rated motor
speed.
To calibrate MAX SPD:
1. Set the MAX SPD trimpot full CCW.
2. Turn the speed adjust potentiometer full CW or set the input signal for maximum
speed.
3. Adjust the MAX SPD trimpot until the desired maximum motor speed is reached.
Note: Check the MIN SPD and MAX SPD settings after recalibrating to verify that the
motor runs at the desired minimum and maximum speeds.
