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
Ω
Current: 4–6 mA
(In case of shorted to
SC)
Voltage:
21–26V (In case of
open from SC)
Logic: source logic.

Safety stop input
terminal common
Common terminal for terminals S1 and S2.
Connected to terminal PC inside of the
inverter.

SO
Safety monitor output
(open collector out-
put)
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 con-
duct).)
If High is output when both of terminals S1
and S2 are open, refer to the "FR-D700
SC EC – Safety stop function instruction
manual, document no.: BCN-A211508-
005“ for the cause and countermeasure.
Load:
24VDC/0.1A max.
Voltage drop:
3.4V max.
(In case of 'ON' state)
