11.2 Deceleration Trimpot (DECEL) – The DECEL Trimpot controls the amount of
ramp-down time when the Main Speed Potentiometer is adjusted to a lower
speed. The DECEL Trimpot has been factory set to 2 seconds, which is the
amount of time it will take for the motor to decelerate from full speed to zero
speed. To increase the deceleration time, rotate the DECEL Trimpot clockwise.
To decrease the deceleration time, rotate the DECEL Trimpot counterclock-
wise. See Figure 15.
Note: The deceleration time cannot be made less than the natural coast time
of the motor and actual load.
11.3 Minimum Speed Trimpot (MIN) – The MIN Trimpot sets the minimum
speed of the motor when the Main Speed Potentiometer is set fully coun-
terclockwise. 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 16.
Note: Readjusting the MIN Trimpot will affect the maximum speed set-
ting. 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.
11.4 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 clock-
wise. To decrease the maximum speed, rotate the MAX Trimpot counterclockwise. See Figure 17.
CAUTION! Do not set the maximum speed above the rated motor RPM since unstable motor
operation may occur.
