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 ve restarts, or input voltage is removed.

@ SPEED AT SPEED - The relay energizes when the drive reaches the

speed setpoint. To avoid a “chattering” relay (energizing and

de-energizing), due to small uctuations in speed, the relay will

remain energized as long as the actual speed is within + 0.50

Hz of the speed setpoint.

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

SPEED #3 value. Refer to Parameter 3 - SPEED #3 in Section

18 - DESCRIPTION OF PARAMETERS.

I LIMIT CURRENT LIMIT - The relay energizes when the drive is

operating in current limit. Once the current limit relay is energized,

it remains energized for a minimum of 500ms, regardless of

whether the drive is still in current limit. At the end of the 500ms

interval, the relay will de-energize if the drive is no longer in

current limit. Refer to Parameter 16 - CURRENT in Section 18

- DESCRIPTION OF PARAMETERS.

AUT/MAN AUTO/MANUAL MODE - The relay energizes when the drive is in

the AUTOMATIC mode, and de-energizes in the MANUAL mode.

Refer to Section 14.2.5 - SPEED REFERENCE SELECTION.

FLWR PR FOLLOWER PRESENT - The relay energizes when the analog

input reference signal at TB-5B is greater than 2 mA, and de-

energizes if the signal falls below 2 mA.

MIN/MAX MIN/MAX ALARM - The relay energizes when the feedback signal

(in PID mode) or the speed reference signal (in open-loop speed

mode) is within the limits set by MIN ALRM and MAX ALRM

(Parameters 81 and 82), and de-energizes when the signal falls

below the MIN ALRM setting or exceeds the MAX ALRM setting.

/ MIN/MAX INVERSE MIN/MAX ALARM - The relay de-energizes when the

feedback signal (in PID mode) or the speed reference signal (in

open-loop speed mode) is within the limits set by MIN ALRM

and MAX ALRM (Parameters 81 and 82), and energizes when

the signal falls below the MIN ALRM setting or exceeds the MAX

ALRM setting.
