*1 Pr.340="12, 22"
The setting of "12, 22" chooses the network operation mode, which is mainly used for computer link
operation (when the FR-A5NR is connected).
*2 The values "10, 12" set in Pr.340 are valid only when Pr.79="0, 2, 6". (When Pr.79="7, 8", the inverter
operates in the same manner as when Pr.340="0". Therefore, the inverter will not operate in the network
operation mode at powering on.)
*3 Pr.340="20, 22" are valid only when Pr.79="0, 2, 8" (EC version only). (When Pr.79="6, 7", the inverter
operates in the same manner as when Pr.340="0" and will not operate in the network operation mode at
power on.)
*4 Pr.340="20, 22" are valid only when Pr.79="0, 2, 6, 8" (NA version only). (When Pr.79="7", the inverter
operates in the same manner as when Pr.340="0" and will not operate in the network operation mode at
power on.)
*5 When the X66 signal is not assigned to the input terminal, the inverter starts in the same operation mode
as when Pr. 340="0" for Pr.340="20" and Pr.340="2" for Pr.340="22".
Note: 1. Change of the Pr.340 setting is made valid when powering on or resetting the inverter.
2. When Pr.340="0, 1, 10, 20", computer programming, which has stopped due to an
instantaneuous power failure or the like during network operation, remains stopped even if power
is recovered.
"9999") when Pr.340="2, 12, 22", a start command during power off (including instantaneous
power failure and power failure) is stored. Therefore, the inverter resumes operation in the state
before powering off at powering on (power restoration) again.
3. When "10, 12, 20, 22" are copied to the inverter which is not available with "10, 12, 20, 22" for
Pr.340, the inverter operates in the same manner as when Pr. 340="0". For operation when
Pr.340="0, 1, 2", refer to the instruction manual of each communication option.
Mode at Power On or at Restoration from Instantaneous Power Failure
Inverter operates in the network operation mode.
X66 signal OFF
Operation mode can be switched to the PU operation mode by the PU.
X66 signal ON Inverter operates in the network operation mode.
Without X66 signal
Pr.340="20" : Inverter operates in the external operation mode.
(*5)
Pr.340="22" : Inverter operates in the network operation mode.
assignment
Inverter operates in the PU operation mode.
X66 signal OFF Inverter operates in the external operation mode.
X66 signal ON Inverter operates in the network operation mode.
Without X66 signal
Pr.340="20" : Inverter operates in the external operation mode.
(*5)
Pr.340="22" : Inverter operates in the network operation mode.

Running frequency (speed) is set in the PU operation mode and the start signal is set in the
external operation mode.
Running frequency (speed) is set in the external operation mode and the start signal is set in
the PU operation mode.
Inverter operates in the programmed operation mode.
Inverter operates in the external operation mode.
Operation mode can be changed without changing the operating status.
Inverter operates in the external

Without X66 signal Pr.340="20" :Inverter operates in the external operation mode.
assignment (*5) Pr.340="22": Inverter operates in the network operation mode.
When the X12 signal is ON, the inverter operates in the external operation mode. (operation
mode can be switched to the PU operation mode by the PU.)
When the X12 signal is OFF, the inverter operates in the external operation mode.
X16 signal OFF....... Inverter operates in the PU operation mode.
X66 signal OFF
X16 signal ON ......... Inverter operates in the external operation mode.
Inverter operates in the network operation mode independently of the
