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.
