5.6.2 Startup of the inverter 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.

Restart coasting time ≠ "9999", the inverter continues running at the condition before the instantaneous failure. When Pr.340 = "1 or 10", if a
power failure occurs while the start signal is being input through communication, the start signal is OFF at power restoration.
