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.
