Terminal Name
AC power input Connect to the commercial power supply.
Inverter output Connect a three-phase squirrel-cage motor.
Connect a brake resistor (FR-ABR, MRS type, MYS type) across terminals P/+
Brake resistor connection and PR.
(The brake resistor cannot be connected to the 0.1K or 0.2K.)
Brake unit connection Connect the brake unit (FR-BU2).
DC reactor connection Remove the jumper across terminals P/+ and P1 and connect a DC reactor.
Earth (Ground) For earthing (grounding) the inverter chassis. Must be earthed (grounded).
Even when the main circuit power supply is
24V external power
OFF, FL-net communication continues with the
supply
input from the 24V external power supply.

Terminal S1/S2 are safety stop signals for use
with in conjunction with an approved external
Safety stop input
safety unit. Both terminal S1/S2 must be used in
(Channel 1)
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
Safety stop input
shorted with terminal PC by shorting wire.
(Channel 2)
Remove the shorting wire and connect the
safety relay module when using the safety stop
function.
Safety stop input terminal
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
Open collector output Y0
in operation statuses other than above.
(safety monitor output 2)
(Low indicates that the open collector output
transistor is ON (conducts). High indicates that
the transistor is OFF (does not conduct).)

With the FL remote communication connector, FL remote communication can
be performed.
