1–5Installing and Wiring Your ControlNet Adapter Board
Publication 1336 FORCE–5.18 ––March, 1999
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 CNA 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 CNA 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 CNA 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 an AC input 1336 FORCE.
If external fault input voltage is removed, the
External Fault LED D5 on the CNA Board is
illuminated. The drive then issues a fault or
warning based on the fault configuration defined
by parameters 88 and 89. (Ext Fault is not
available on common DC bus input drives.)
