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).

key is pressed.
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.
