Terminal name Terminal function description
1 changeover contact output that indicates that
an inverter's protective function has been
activated and the outputs are stopped.
Relay output 1 (fault
output)
Fault: discontinuity across B and C (continuity
across A and C), Normal: continuity across Band C
(discontinuity across A and C)
Relay output 2 1 changeover contact output
Switched to LOW when the inverter output
frequency is equal to or higher than the starting
Inverter running
frequency (initial value 0.5 Hz). Switched to HIGH
during stop or DC injection brake operation.
Switched to LOW when the
output frequency is within
the set frequency range
Up to frequency
±10% (initial value). Switched
to HIGH during acceleration/
deceleration and at a stop.
Switched to LOW when stall
prevention is activated by
Overload warning the stall prevention function.
Switched to HIGH when stall
prevention is cancelled.
Switched to LOW when an
instantaneous power failure
Instantaneous power
occurs or when the
failure
undervoltage protection is
activated.
Switched to LOW when the
inverter output frequency is
equal to or higher than the
Frequency detection preset detection frequency,
and to HIGH when it is less
than the preset detection
frequency.

Outputs a selected
monitored item (such as
output frequency) among
several monitored items. The
