Relay output (fault
output)
1 changeover contact output indicates that the inverter
protective function has activated and the output stopped.
Fault: discontinuity across B-C (continuity across A-C),
Normal: continuity across B-C (discontinuity across A-C) Contact capacity:230VAC

RUN Inverter running
Switched Low when the inverter output frequency is equal to
or higher than the starting frequency (initial value 0.5Hz).
Switched High during stop or DC injection brake operation.
(Low is when the open collector output transistor is ON
(conducts). High is when the transistor is OFF (does not
conduct).)

Select one e.g. output frequency
from monitored items.
Not output during inverter reset.
The output signal is proportional to
the magnitude of the
corresponding monitored item.
To set a full-scale value for
monitoring the output frequency
and the output current, set
Pr. 55
and Pr. 56.

NOTE
The terminals S1, S2, SC, and SO are for manufacturer setting. Do not connect anything to these.
Doing so may cause an inverter failure. Do not remove the shortening wires across the terminals S1 and SC and the
terminals S2 and SC. Removing either shortening wire disables the inverter operation.
