Startup In Network Operation Mode At Power-On - Mitsubishi Electric 800 Series Instruction Manual

(D) Operation command and frequency command
5.9.2

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.

Use Pr.340="2 or 12" setting to perform communication with the RS-485 terminals.
Even if an instantaneous power failure occurs while Pr.57 Restart coasting time ≠ "9999" (with automatic restart after instantaneous power
failure), inverter continues operation at the condition before the instantaneous failure.

The operation mode cannot be directly changed between the PU operation mode and Network operation mode.

The inverter starts up in the Network operation mode.
1, 2 If an instantaneous power failure occurs when "2" is set, the operating
status before the instantaneous power failure is maintained.
The inverter starts up in the Network operation mode. The operation
mode can be changed between the PU operation mode and Network
10, 12 operation mode from the operation panel.
If an instantaneous power failure occurs when "12" is set, running is
continued at the condition before the instantaneous power failure.
