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.

S1
Safety stop input
(Channel 1)
Terminals S1 and S2 are for safety stop input signals used
with the safety relay module. Terminals S1 and S2 are used
simultaneously (dual channel). Inverter output is shut off by
shortening/opening across terminals S1 and SC and across
S2 and SC. In the initial status, terminals S1 and S2 are
shorted with terminal SC by shortening wire.
Remove the shortening wire and connect the safety relay
module when using the safety stop function.
Input resistance: 4.7k

Current: 4 to 6 mA
(In case of shorted to
SC)
Voltage: 21 to 26 V

S2
Safety stop input
(Channel 2)
SO
Safety monitor output
(open collector output)
The signal indicates the status of safety stop input. Low
indicates safe state, and High indicates drive enabled or fault
detected.
(Low is when the open collector output transistor is ON
(conducts). High is when the transistor is OFF (does not
conduct).)
If High is output when both of terminals S1 and S2 are open,
refer to the Safety stop function instruction manual (BCN-A211508-
000)
for the cause and countermeasure.
(Please contact your sales representative for the manual.)
Load: 24VDC/0.1A max.
Voltage drop: 3.4V max.
