S1 Safety stop input (Channel 1)
Terminals S1 and S2 are used for the safety stop input signal for
the safety relay module. Terminals S1 and S2 are used at the
same time (dual channel).
Inverter output is shutoff by shortening/opening between
terminals S1 and SIC, or between S2 and SIC.
In the initial status, terminals S1 and S2 are shorted with
terminal PC by shorting wires. Terminal SIC is shorted with
terminal SD. Remove the shorting wires and connect the safety
relay module when using the safety stop function.
Input resistance 4.7 k
Input current 4 to 6
mADC (with 24 VDC
input)
S2 Safety stop input (Channel 2)

Common terminal for terminals S1 and S2. —
So (SO)
Safety monitor output (open
collector output)
Indicates the safety stop input signal status.
Switched to LOW when the status is other than the internal
safety circuit failure. Switched to HIGH during the internal safety
circuit failure status.
(LOW is when the open collector output transistor is ON
(conducted). HIGH is when the transistor is OFF (not
conducted).)
Refer to the Safety stop function instruction manual when the
signal is switched to HIGH while both terminals S1 and S2 are
open. (Please contact your sales representative for the
manual.)
