Operation
Automatic restart upon power restoration
After a one-second time delay, all drives automatically run to set speed when power
is applied.
Line starting and line stopping
Line starting and line stopping (applying and removing AC
line voltage) is recommended for infrequent starting and stopping of a drive only.
When AC line voltage is applied to the drive,
the motor accelerates to the speed set by the speed adjust potentiometer. When AC
line voltage is removed, the motor coasts to a stop.
Decelerating to minimum speed
Connect the switch as shown in Figure 8 (page 19). Close the switch between S1 and
S2 to decelerate the motor from set speed. Open the switch to accelerate the motor
to set speed.
Dynamic braking
Dynamic braking may be used to rapidly stop a motor (see Figure 9, page 20). For
the RUN/BRAKE switch, use a double pole, double throw switch rated for at least the
maximum DC armature voltage and maximum braking current.
