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.
