Figure 10. Run/Decelerate to Minimum Speed Switch

Minimum speed

The circuit shown in Figure 10 may be used to decelerate a

motor to a minimum speed. Closing the switch between S1

and S2 decelerates the motor from set speed to a 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.
