About the setting values "10 and 12" of Pr. 340 "link startup mode selection"
You can switch operation between the PU operation and network operation when using with the
communication option. The inverter starts up in the network operation mode and operation can be switched
between the PU operation and network operation from the operation panel (FR-DU04) or parameter unit.
*1 Refer to page 106 for Pr. 72 "operation mode selection."
*2 Pr. 340="12"
When values other than "9999" are set in Pr. 57 (with restart) and a start command is given from
network, a start command at powering off (including instantaneous power failure and power failure) is
stored. Therefore, the inverter will resume the same operation state in the network operation mode
which was in before powering off when powering on (power restoration) next time.
*3 When Pr. 79 = "7 or 8", the inverter operates in the same manner as when Pr. 340 = "0". (The inverter
will not operate in the network operation mode at powering on.)
When Pr.340="10 or 12" and Pr.79="0 or 6", operation can be switched between the PU operation and
network operation from the operation panel (FR-DU04) or parameter unit (FR-PU04).
• FR-DU04
Shifts to the PU operation mode when is displayed on the operation mode switching menu and
shifts to the network operation when is displayed.
• FR-PU04
Shifts to the PU operation mode when the key is pressed and to the network operation mode when the
key is pressed.

PU or network
operation
Inverter operates in the network operation mode. Operation mode can be
switched between the PU operation and the network operation.
1 PU operation Inverter operates in the PU operation mode.
2 Network operation Inverter operates in the network operation mode.
3
External/PU combined
operation
Running frequency is set in the PU operation mode and the start signal is set in
the external operation mode.
4
External/PU combined
operation
Running frequency is set in the external operation mode and the start signal is
set in the PU operation mode.
5 Programmed operation Inverter operates in the programmed operation mode.
6 Switch-over
Inverter operates in the network operation mode. Operation mode can be
switched between the PU operation and the network operation.
7(*3) PU operation interlock
X12 signal ON . . . . . . . . . . . . . Inverter operates in the external operation
mode. (Operation mode can be switched to the
PU operation mode by the parameter unit.)
X12 signal OFF . . . . . . . . . . . . Inverter operates in the external operation
mode.

Operation mode switch-
over by the external
signal
X16 signal ON . . . . . . . . . . . . . Inverter operates in the external operation
mode.
X16 signal OFF . . . . . . . . . . . . Inverter operates in the PU operation mode.
Note: 1. Change of the Pr. 340 setting is made valid when powering on or resetting the inverter.
2. When copying parameters to the inverter which is not available with Pr.340="10, 12", the inverter
operates in the same manner as when Pr. 340 = "0".
For Pr. 340="0, 1, 2", refer to the instruction manual of each communication option.
