Even when the main circuit power supply is OFF, FL
remote communication continues with the input from
the 24V external power supply.
Common terminal for the terminal +24
Terminal S1/S2 are safety stop signals for use with in
conjunction with an approved external safety unit.
Both terminal S1/S2 must be used in dual channel
form. Inverter output is shutoff depending on shorting/
opening between S1 and PC, S2 and PC.
In the initial status, terminal S1 and S2 are shorted
with terminal PC by shorting wire.
Remove the shorting wire and connect the safety
relay module when using the safety stop function.
Common terminal for safety stop input terminals S1
and S2.
This terminal is switched to Low during the operation
with no internal safety circuit fault (E.SAF, E.6, E.7,
E.CPU). It is switched to High in operation statuses
other than above.
(Low indicates that the open collector output transistor
is ON (conducts). High indicates that the transistor is
OFF (does not conduct).)
Common terminal of terminal Y0.
With the FL remote communication connector, FL remote communication can be performed.
