ABOVE PRSET #3 ABOVE PRESET SPEED #3 - The relay energizes when the
output frequency exceeds the PRESET #3 value, and de-
energizes when the output frequency returns to a value lower
than the PRESET #3 value. Refer to Parameter 3 - PRESET #3
in Section 18.0 - 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 18.0 - DESCRIPTION OF
PARAMETERS.
AUTO/HAND SRC The relay energizes when the drive speed is controlled by the
AUTO SOURCE, and de-energizes when the drive speed is
controlled by the HAND SOURCE. Refer to Section 14.2.4 -
SPEED REFERENCE SELECTION.
FOLLOWER PRES 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 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 ALARM and MAX ALARM (Parameters
81 and 82), and energizes when the signal falls below the MIN
ALARM setting or exceeds the MAX ALARM setting.
INV MIN/MAX A INVERSE 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 ALARM
and MAX ALARM (Parameters 81 and 82), and de-energizes
when the signal falls below the MIN ALARM setting or exceeds
the MAX ALARM setting.
MIN ALARM The relay de-energizes when the feedback signal (in PID mode)
or the speed reference signal (in open-loop speed mode)
equals or exceeds the MIN ALARM setting (Parameter 81), and
energizes when the signal falls below the MIN ALARM setting.
INV MIN ALARM INVERSE MIN ALARM - The relay energizes when the feedback
signal (in PID mode) or the speed reference signal (in open-
loop speed mode) equals or exceeds the MIN ALARM setting
(Parameter 81), and de-energizes when the signal falls below
the MIN ALARM setting.
MAX ALARM The relay de-energizes when the feedback signal (in PID mode)
or the speed reference signal (in open-loop speed mode) is less
than or equal to the MAX ALARM setting (Parameter 82), and
energizes when the signal exceeds the MAX ALARM setting.
INV MAX ALARM INVERSE MAX ALARM - The relay energizes when the feedback
signal (in PID mode) or the speed reference signal (in open-loop
speed mode) is less than or equal to the MAX ALARM setting
(Parameter 82), and de-energizes when the signal exceeds the
MAX ALARM setting.
RUN REVERSE Energizes when the drive is running in reverse rotation, and de-
energizes when running in forward rotation.
