5.6.2 Startup in Network operation mode at power-ON
When power is switched ON or when power comes back ON after an instantaneous power failure, the inverter can be started
up in the Network operation mode. After the inverter starts up in the Network operation mode, parameter writing and operation
can be commanded from programs.
Set this mode when performing communication operation using the RS-485 terminals or a communication option.
