NOTE
Set Pr. 267 and a voltage/current input switch correctly, then input analog signals in accordance with the settings.
Applying a voltage with voltage/current input switch in "I" position (current input is selected) or a current with switch in
"V" position (voltage input is selected) could cause component damage of the inverter or analog circuit of output
devices. (Refer to page 150 for details.)

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)

Open collector
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 indicates that the open collector output transistor is on
(conducts).
High indicates that the transistor is off (does not conduct).)

S1
Inverter output shutoff
(Line 1)
Inverter output is shutoff depending on shorting/opening between S1 and SC, S2 and SC.
At initial state, terminal S1 and S2 are shorted to terminal SC with a shorting wire.
When using the safety stop function, remove this shorting wire, and connect to a safety
relay module.
