Application Notes

Decelerating to minimum speed

The switch shown in Figure 8 may be used to decelerate a
motor to minimum speed. Closing the switch between S1 and
S2 decelerates the motor from set speed to minimum speed
determined by the MIN SPD trimpot setting. If the MIN SPD
trimpot is set full CCW, the motor decelerates to zero speed
when the switch between S1 and S2 is closed. The DECEL
trimpot setting determines the rate at which the drive
decelerates. By opening the switch, the motor accelerates to set
speed at a rate determined by the ACCEL trimpot setting.
