50 TB13D

(TB-13D FUNCTION)

STOP (TB-1) and 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 (see 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 .

EXT 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 .

EXT / 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 .

EXT CLEAR

Sets TB-13D as a normally open FAULT RESET . Close TB-13D to TB-2 to clear a

fault .

NOTE:

When set to CLEAR, TB-13D becomes the only terminal that can be used to clear a fault (TB-1

will not work). However, the keypad STOP key can still be used to clear faults.

52 TB14B OUT

(TB-14 OPEN COLLECTOR OUTPUT)

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.

/FAULT

INVERSE FAULT - The relay energizes when the drive “trips” into a fault condition,

and remains energized until the fault condition is cleared.

LOCK

FAULT LOCKOUT - This relay 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 .

@ SPEED

AT SPEED - The relay energizes when the drive reaches the speed set point. 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 ± 3 Hz of the speed

set point .

ABOVE #3

ABOVE SPEED #3 - The relay energizes when the output frequency exceeds the speed

#3 value, and de-energizes when the output frequency returns to a value lower than the

69
