Mitsubishi Electric FR-F740 EC Instruction Manual page 393

Parameter
Specify operation mode at power on (Pr. 340)
Depending on the Pr. 79 and Pr. 340 settings, the operation mode at power on (reset) changes
as described below:
Pr. 340
0
(initial
value)
1 / 2
10 / 12
Tab. 6-49:
The Pr. 340 setting "2" or "12" is mainly used for communication operation using the inverter
RS485 terminals. When Pr. 57 "Restart coasting time" ≠ 9999 (selection of automatic restart
after instantaneous power failure), the inverter will resume the same operation state which
was in before after power has been restored from an instantaneous power failure.
The operation mode cannot be switched directly between the PU operation mode and
network operation mode.
Operation mode can be changed between the PU operation mode and network operation
mode with the PU/EXT key of the operation panel (FR-DU07) and X65 signal.
