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 (input contactor, etc.) 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.
Input Contactor
ATTENTION: An incorrectly applied or installed
system can result in component damage or reduction in
product life. Follow these recommendations for
application of an input contactor to a 1305 drive.
Normal Operation: After the input contactor is closed, the
enable, start, and stop signals may be applied. These control
signals must be removed before opening the input contactor.
The input contactor must not be opened and closed 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.
