Decelerating to minimum speed
A single pole, single throw switch may be used to decelerate a
motor to minimum speed (see Figure 9). Close the switch between
S1 and S2 to decelerate the motor from set speed to minimum
speed. Open the switch to accelerate the motor from minimum
speed to set speed. The ACCEL trimpot setting determines the rate
at which the motor accelerates.
