operation location

3.17.2 Operation mode at power on (Pr. 79, Pr. 340)

When power is switched on or when power comes back on after instantaneous power failure, the inverter can

be started up in network operation mode.
Pr. 80
After the inverter has started up in the network operation mode, parameter write and operation can be

*1 The Pr. 340 setting "2" or "12" is mainly used for communication operation using the inverter RS-485 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.
*2 The operation mode cannot be switched directly between the PU operation mode and network operation mode.
*3 Operation mode can be changed between the PU operation mode and network operation mode with
and X65 signal.
