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.)
(2) Output signal
Terminal
Type Terminal Name
Symbol
1 changeover contact output indicates that the inverter
Relay output (fault protective function has activated and the output stopped.
A, B, C
output) Fault: discontinuity across B-C (continuity across A-C),
Normal: continuity across B-C (discontinuity across A-C)
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.
RUN Inverter running
(Low indicates that the open collector output transistor is on
(conducts).
High indicates that the transistor is off (does not conduct).)
Open collector output
SE Common terminal of terminal RUN.
common
Select one e.g. output
frequency from monitor
items. Not output during
inverter reset.
AM Analog signal output
The output signal is
proportional to the magnitude
of the corresponding
monitoring item.

Inverter output shutoff
Inverter output is shutoff depending on shorting/opening between S1 and SC, S2 and SC.
S1
(Line 1)
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
Inverter output shutoff
S2
relay module.
(Line 2)
SO
Output shutoff terminal
SC Common terminal for terminals S1, S2. Connected to terminal SD inside of the inverter.
