LEESON Chassis Mount PWM Control: 175292.00 - Manual (Page 28)

MINIMUM SPEED (MIN SPD)
The MIN SPD setting determines the motor speed when the speed
adjust potentiometer is turned full CCW. It is factory set for zero
speed.
To calibrate MIN SPD:
1. Set the MAX SPD trimpot to full CW.
2. Set the MIN SPD trimpot to full CCW.
3. Turn the main speed adjust potentiometer to full CCW. If an
input voltage is used instead of a speed adjust potentiometer,
set the input signal to minimum.
4. Adjust the MIN SPD trimpot until the desired minimum motor
speed is reached.
MAXIMUM SPEED (MAX SPD)
The MAX SPD setting determines the motor speed when the speed
adjust potentiometer is turned full CW. It is factory set for maximum
rated speed.
To calibrate MAX SPD:
1. Set the MAX SPD trimpot full CCW.
2. Apply power to the drive and turn the speed adjust
potentiometer full CW. If an input voltage signal is used instead
of a speed adjust pot, set the input signal to maximum.
3. Adjust the MAX SPD trimpot until the desired maximum motor
speed is reached.
