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, turn the speed adjust potentiometer full CCW.
Adjust the MIN SPD trimpot until the motor has stopped, or
is running at the desired minimum speed.
Each drive is factory calibrated to its maximum current rating.
Re-adjust the calibration trimpot settings to accomodate
lower current motors.
All adjustments increase with CW rotation, and decrease with
CCW rotation. Use a non-metallic screwdriver for calibration.
Each trimpot is identified on the printed circuit board.
Minimum Speed (MIN 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, set the MAX SPD trimpot full CCW. Turn the
speed adjust potentiometer full CW. Adjust the MAX SPD
trimpot until the desired maximum motor speed is reached.
NOTE: Check the MIN SPD and MAX SPD adjustments after
recalibrating to verify that the motor runs at the desired
minimum and maximum speeds.
