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.
INV MIN/MAX A 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 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.
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.
SLEEP The relay energizes when the drive is in SLEEP MODE. Refer
to Parameters 36 - 38.
SPD = 0HZ The relay energizes when there is no output to the motor, for
any reason, such as: drive is in STOP mode, drive is in RUN
mode but the speed command is 0 Hz, drive is in SLEEP mode,
drive has tripped into a fault, etc.
The open-collector output circuit is a current-sinking type rated at 30 VDC and 40
mA maximum. An external power supply (30 VDC max.) must be used to power
the open-collector outputs. The drive does not have a dedicated power supply for
the open-collector outputs.

TB15 OUT (TB-15 OPEN COLLECTOR OUTPUT)
This parameter sets the open-collector output indication for terminal TB-15. It has
the same functionality as Parameter 52 - TB14 OUT above.
54
RELAY (RELAY FUNCTION)
The control board has one set of FORM C relay contacts at TB-16, 17, and 18
that can be programmed for the same indications as the open-collector outputs
described in parameter 52.
