7.2 Deceleration Trimpot (DECEL)
The DECEL Trimpot controls the amount of rampdown time when the Main Speed Potentiometer is
adjusted to a lower speed. The DECEL Trimpot is 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
counterclockwise. The DECEL Trimpot range is 0.2 – 10 seconds.
See Figure 7-2.
Note:
If the DECEL Trimpot is set to greater than the natural coast time of the motor and actual load, it
will extend the deceleration time of the motor.

7.3 Minimum Speed Trimpot (MIN)
The MIN 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. The MIN Trimpot range is 0% – 30% of base motor speed.
See Figure 7-3.
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.
