Relay output 1 (fault
output)
1 changeover contact output that indicates that an
inverter's protective function has been activated and
the outputs are stopped.
Fault: discontinuity across B and C (continuity across
A and C), Normal: continuity across Band C
(discontinuity across A and C)

Open collector
RUN SE Inverter running
Switched to LOW when the inverter output frequency
is equal to or higher than the starting frequency (initial
value 0.5 Hz). Switched to HIGH during stop or DC
injection brake operation.
Permissible load 24 VDC
(maximum 27 VDC) 0.1 A
(The voltage drop is 2.8 V
at maximum while the
signal is ON.)
LOW is when the open
collector output transistor
is ON (conducted).
HIGH is when the
transistor is OFF (not
conducted).
SU SE Up to frequency
Switched to LOW when
the output frequency is
within the set frequency
range 10% (initial value).
Switched to HIGH during
acceleration/deceleration
and at a stop.
Fault code (4 bits)
output.
(Refer to the FR-F800
Instruction Manual
(Detailed).)
OL SE Overload warning
Switched to LOW when
stall prevention is
activated by the stall
prevention function.
Switched to HIGH when
stall prevention is
canceled.
IPF SE
Instantaneous power
failure
Switched to LOW when
an instantaneous power
failure occurs or when the
undervoltage protection is
activated.
FU SE Frequency detection
Switched to LOW when
the inverter output
frequency is equal to or
higher than the preset
detection frequency, and
to HIGH when it is less
than the preset detection
frequency.
Pulse
FM
SD
For meter
Outputs a selected
monitored item (such as
output frequency) among
several monitored items.
The signal is not output
during an inverter reset.
The output signal is
proportional to the
magnitude of the
corresponding monitoring
item.
Use Pr.55, Pr.56, and
Pr.866 to set full scales
for the monitored output
frequency, output current,
and torque.
(Refer to the FR-F800
Instruction Manual
(Detailed).)
