TB13D INPUT
WARNING!
EXTERNAL FAULT (TB-13D) circuitry may be disabled if parameters
are reset to factory defaults! The drive must be reprogrammed after
a RESET in order to insure proper operation (refer to Parameter
65 - PROGRAM).
FAILURE TO DO SO MAY RESULT IN DAMAGE TO EQUIPMENT
AND/OR INJURY TO PERSONNEL!
This parameter selects the function for TB-13D. The following settings are available:
EXTERN FAULT
Sets TB-13D as a normally open EXTERNAL FAULT contact.
Close TB-13D to TB-2 to trip the drive into an EXTERNAL
FAULT.
EXTERN / FAULT
Sets TB-13D as a normally closed EXTERNAL FAULT contact.
Open TB-13D to TB-2 to trip the drive into an EXTERNAL
FAULT.
EXTERN
CLEAR
Sets TB-13D as a normally open EXTERNAL FAULT RESET.
Close TB-13D to TB-2 to clear a fault.
NOTE:
When set to EXTERN CLEAR, TB-13D becomes the only terminal that can
be used to clear a fault (TB-1 will not work). However, the keypad OFF
(STOP) key can still be used to clear faults.

TB14/RELAY #2
This parameter sets the open-collector output indication for terminal TB-14. The
following conditions can be selected:
NONE
This setting disables the output.
RUN
The relay energizes when the drive is given a START command,
and remains energized until: a STOP command is given and
the output frequency has decelerated to 0.5 Hz, the drive has
“tripped”, or the input voltage is removed. Note that this relay
indicates only that the drive is in the RUN mode. It does not
necessarily indicate that the motor is turning.
FAULT
The relay energizes when input voltage is applied to the drive
and remains energized until the drive “trips” into a fault condition,
or input voltage is removed.
INVERSE FAULT
The relay energizes when the drive “trips” into a fault condition,
and remains energized until the fault condition is cleared.
FAULT
LOCKOUT
This setting is used when the drive is programmed to
automatically restart after a fault. The relay energizes when
input voltage is applied to the drive and remains energized until
the drive has faulted and unsuccessfully attempted five restarts,
or input voltage is removed.
AT SPEED
The relay energizes when the drive reaches the speed setpoint.
To avoid a “chattering” relay (energizing and de-energizing), due
to small fluctuations in speed, the relay will remain energized as
long as the actual speed is within + 0.5 Hz of the speed setpoint.
