REMARKS
When performing onlin e exchange
The built-in terminating res istor can not be exchanged online since the terminating resistor is on the FR-A7NC board and
disconnected when the terminal block is removed from the FR-A7NC connector for communication. When changing the FRA7NC online, connect a terminating resistor supplied with a PLC master module to the FR-A7NC after modifying it and do
not use the internal terminating resistor (SW2 1-OFF, 2-OFF).
Connection wit h the t erminating resistor
Connect the termin at ing resistor between termin al s
DA-DB of the FR-A7NC at th e end.
Modify the terminating resistors supplied w ith t he

⋅ If the terminal block of the FR - A7NC is removed, built-in terminating resistor can not be used. (Refer to page 8.)
AUTION
When installing the inverter front cover, the cables to the inverter's control circuit terminals and
option terminals should be routed properly in the wiring space to prevent them from being
caught between the inverter and its cover.
After wiring, wire offcuts must not be left in the inverter. They may cause an error, failure or
malfunction.

INVERTER SETTING
4.2 Operation Mode Setting
The inverter mounted with a communication option has three operation modes.
(1) PU operation [PU].............. Controls the inverter from the key of the operation panel (FR-DU07)
mounted on the inverter.
(2) External operation [EXT] ...Controls the inverter by switching on/off external signals connected to the
control circuit terminals of the inverter.
(The inverter is factory-set to this mode.)
(3) Network operation [NET]...Controls the inverter with instructions from the network via the
communication option.
(The operation signal and running frequency can be entered from the
control circuit terminals depending on the Pr. 338 Communication operation
command source and Pr. 339 Communication speed command source setting.
Refer to page 21.)

(1) Operation mode switching conditions
Before switching the operation mode, check that:
1) The inverter is at a stop;
2) Both the STF and STR signals are off; and
3) The Pr. 79 Operation mode selection setting is correct.
(Set with the operation panel of the inverter.)
Refer to the inverter manual (applied) for details of Pr. 79.
(2) Operation mode selection at power on and at re stora tion f rom instantaneous power failure
The operation mode at power on and at restoration from instantaneous power failure can be selected.
Set a value other than "0" in Pr. 340 to select the network operation mode.
After started in network operation mode, parameter write from the network is enabled. (Refer to page 6 9 for
a program example for parameter write.)
REMARKS
1. Change of the Pr. 340 setting is made valid when powering on or resetting the inverter.
2. Pr. 340 can be changed with the operation panel independent l y of the operation mode.
