INPUT DEVICES
Starting and Stopping the Motor
ATTENTION: The drive start/stop control
circuitry includes solid-state components. If
hazards due to accidental contact with moving
machinery or unintentional flow of liquid, gas or
solids exist, an additional hardwired stop circuit is
required to remove AC line power to the drive.
When AC input power is removed, there will be a
loss of inherent regenerative braking effect and
the motor will coast to a stop. An auxiliary
braking method may be required.
Repeated Application/Removal of Input Power
ATTENTION: The drive is intended to be
controlled by control input signals that will start
and stop the motor. A device that routinely
disconnects then reapplies line power to the drive
for the purpose of starting and stopping the motor
should not be used. If it is necessary to use this
method for starting and stopping or if frequent
cycling of power is unavoidable, make sure that it
does not occur more than once a minute.
Bypass Contactors
ATTENTION: An incorrectly applied or
installed system can result in component damage
or reduction in product life. The most common
causes are:
D Wiring AC line to drive output or control
terminals.
D Improper voltage placed on control terminals.
D Improper bypass or output circuits not
approved by Allen-Bradley.
D Output circuits which do not connect directly
to the motor.
D Incorrect or inadequate AC supply.
D Excessive ambient temperature.
Contact Allen-Bradley for assistance with
application or wiring.
