The following are the signals that may be used:
This signal: Has the following meaning:
DRIVE
ENABLE
A drive enable signal must be present before the
drive will acknowledge a start command. If LED
D11 drive enable on the PLC Communications
Adapter Board is illuminated, the drive has
received an enable signal allowing drive logic to
accept a start command.
MOTOR
THERMO
A motor thermo signal allows you to connect an
NC motor thermal switch to the 1336 FORCE.
Motor Thermo LED D9 on the PLC
Communications Adapter Board illuminates if a
motor over–temperature condition occurs. The
drive issues a fault or warning based on the fault
configuration defined by VP Fault Select
(parameter 88) and VP Warn Select (parameter
89).
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 you remove ac input power,
there is loss of inherent regenerative
braking effect and the motor coasts to a
stop. An auxiliary braking method may
be required.
!
NORM STOP
A normal stop signal specifies an NC maintained
stop input that stops the drive according to the
stop mode you specified using parameter 59.
The drive responds the same way it would if the
stop bit were set in any logic command. When a
stop signal is present, the Norm Stop LED D7 on
the PLC Communications Adapter Board is
illuminated, and the drive cannot run until the
stop signal is removed.
EXT FAULT
An Ext Fault signal allows you to wire an
external signal into the 1336 FORCE. If external
fault input voltage is removed, the External Fault
LED D5 on the PLC Communications Adapter
Board is illuminated. The drive then issues a
fault or warning based on the fault configuration
defined by parameters 88 and 89.
