7.2 Maximum Speed Trimpot (MAX)
The MAX Trimpot sets the maximum speed of the motor
when the Main Speed Potentiometer is set fully clockwise.
The MAX Trimpot is factory set to 100 % of base motor
speed. To increase the maximum speed, rotate the MAX
Trimpot clockwise. To decrease the maximum speed,
rotate the MAX Trimpot counterclockwise. See Figure 5.
Note: Do not attempt to adjust the MAX speed above the rated
motor RPM, since unstable motor operation may occur.
For moderate changes in the MAX speed, there will be a
slight effect on the MIN speed setting when the MIN
speed is set at zero. There may be significant variation in
the MIN speed setting if the MIN speed is at a higher than
zero setting.
7.3 Minimum Speed Trimpot (MIN)
The MIN speed trimpot sets the minimum speed of the
motor when the Main Speed Potentiometer is set fully
counterclockwise. The MIN Trimpot is factory set to 0 % of
base motor speed. To increase the minimum speed,
rotate the MIN Trimpot clockwise. To decrease the
minimum speed, rotate the MIN Trimpot counterclockwise.
See Figure 6.
Note: Readjusting the MIN Trimpot will affect the maximum
speed setting. Therefore, it is necessary to readjust the
MAX Trimpot if readjusting the MIN Trimpot. It may be
necessary to repeat these adjustments until both the
minimum and maximum speeds are set to the desired
levels.
