LEESON Chassis Mount PWM Control: M1740009.00 - Manual (Page 18)

12 Operation
Line starting and 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.
An inhibit switch allows the motor to decelerate to zero
speed when the switch is closed. Connect a single pole,
single throw switch between H1 and H2 (see Figure 8,
Page 13). Close the switch to decelerate the motor to zero
speed. Open the switch to accelerate the motor to set
speed. An isolated NPN open-collector transistor rated for
at least 10 mA (I
CE
) may also be used as an inhibit switch.
Wire the collector to H1, and the emitter to H2.
Dynamic braking may be
used to rapidly stop a
motor (Figure 9, page 13).
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.
Warning
Wait for the motor to
completely stop before
switching it back to
RUN. This will prevent
high armature currents
from damaging the
motor or drive.
