OFFSET
This trimpot is set at the factory and should not need adjustment.
Do not adjust this trimpot unless you are experiencing drift problems.
Contact your Minarik representative before attempting adjustment.
MAX
Determines the motor speed when the speed adjust potentiometer is
turned full CW. It is factory set for maximum rated speed.
The RG6xU-PCM has a factory-set offset to guarantee stability in a stopped motor.
To calibrate, set the MAX trimpot to full CCW. Turn the speed adjust
pot to full CW. Adjust the MAX trimpot until the desired maximum
motor speed is reached.

NOTE
To calibrate the OFFSET trimpot:
1. Ensure that the input power is turned OFF.
2. Set the input signal to zero.
3. Set the OFFSET trimpot to the approximate midrange or 50%.
Note: This is a 25-turn potentiometer. After setting the trimpot to zero full CCW,
make 12.5 full rotations to reach midrange, or 50%.
4. Apply power and observe the motor.
5. If the motor shaft drifts, or slowly rotates with no signal applied, adjust the OFFSET
trimpot until the motor shaft stops. The direction and amount of trimpot adjustment
depends on the direction of the shaft rotation and connection of the motor leads.
