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)

RUN 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 V DC (maximum
27 V DC) 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).
5-378
SU 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
page 5-402.)
5-390
OL Overload warning
Switched to LOW when stall
prevention is activated by
the stall prevention function.
Switched to HIGH when stall
prevention is cancelled.
5-339
IPF
Instantaneous power
failure
Switched to LOW when an
instantaneous power failure
occurs or when the
undervoltage protection is
activated.
5-581,
5-599
FU 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.

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.
