2. INSTALLATION AND WIRING
2.6 Control circuit
Terminal name
For connecting a safety communication option. For the connection method, refer to the
Instruction Manual of the installed safety communication option.
Communication can be made via Ethernet.

Number of cascade connection stages: Up to 2 (100BASE-TX) / up to 4 (10BASE-T)
Interface: RJ-45
Number of interfaces available: 1
IP version: IPv4
RS-485 communication can be made through the PU connector (For connection on a 1:1 basis
only)
Conforming standard: EIA-485 (RS-485)
Transmission format: Multidrop link
Communication speed: 4800 to 115200 bps
Wiring length: 500 m
A connector (receptacle).
Plug a USB memory device into this
connector to copy parameter settings or use
the trace function.
Mini B connector (receptacle).
By connecting the inverter to a personal
computer via this connector, FR
Configurator2 installed on the computer can
be used for setting the inverter, or monitoring
or testing the inverter operation.
Terminal name
Use this signal to reset a fault output provided when a protective
function is activated. Turn ON the RES signal for 0.1 second or
longer, then turn it OFF.
Reset
In the initial setting, reset is always enabled. Setting Pr.75 makes
reset possible only after the occurrence of a converter unit fault.
The converter will restart about 1 second after reset.
The External thermal relay input (OH) signal is used when using
the external thermal relay or the thermal protector built into the
External thermal
motor to protect the motor from overheating.
relay input
When the thermal relay is activated, the inverter output is shut off
by the external thermal relay operation (E.OHT).
Contact input Use Pr.178 to assign a function to the terminal.
For connecting a 24 V external power supply.
24 V external
If a 24 V external power supply is connected, power is supplied to
power supply input
the control circuit while the main power circuit is OFF.
