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 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 .
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 .50
Hz of the speed setpoint .
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 .
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 .
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 .
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 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 .
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 .
