Calibration
Each drive is factory calibrated to its maximum horsepower rating.
Readjust the calibration trimpot settings to accommodate lower
horsepower motors.
All adjustments increase with clockwise (CW) rotation, and decrease with
counterclockwise CCW rotation. Use a non-metallic screwdriver for
calibration. Each trimpot is identified on the printed circuit board.
Power board trimpots
MIN SPD
MIN SPD may be calibrated if the CCW side of the speed adjust
potentiometer is connected to S0 (S0 is in series with the MIN SPD
trimpot). Since the forward and reverse speed adjust potentiometers are
not connected to S0, MIN SPD cannot be calibrated.
MAX SPD
The MAX SPD trimpot setting determines the motor speed when the
forward (or reverse) 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. Press
FWD
(or
REV
).
3. Turn the forward (or reverse) speed adjust potentiometer full CW.
4. Adjust the MAX SPD trimpot until the desired maximum motor speed
is reached.
The calibrated maximum speed is the same for both forward and reverse
directions.
