*1 Operation mode can not be directly changed between the PU operation mode and network operation mode.
*2 The
Pr. 340
settings "2, 12" are mainly used for communication operation using the inverter RS-485 terminal.
When a value other than "9999" (selection of automatic restart after instantaneous power failure) is set in
Pr. 57 Restart coasting time
, the
inverter will resume the same operation state which was in before after power has been restored from an instantaneous power failure.
When
Pr.340
= "1, 10", a start command turns off if power failure has occurred and then restored during a start command is on.
*3 Operation mode can be changed between the PU operation mode and network operation mode with
of the operation panel (FR-
DU07) and X65 signal.
