Startup Of The Inverter In Network Operation Mode At Power-On - Mitsubishi Electric FR-A800 Series Instruction Manual

3.
Set "66" in one of Pr.178 to Pr.189 to assign the NET-External operation switching signal (X66) to a terminal.
4.
When the X66 signal is ON, the NET operation mode is selected. When the X66 signal is OFF, the External
operation mode is selected.

*1 When Pr.550 NET mode operation command source selection = "0" (communication option control source) and no communication option is
connected, the External operation mode is selected.
*2 When the X16 signal is OFF, the PU operation mode is selected. Also, when the X65 signal is assigned, the operation mode follows the ON/OFF
state of the X65 signal.
NOTE
• The priority of Pr.79 and Pr.340 and signals is as follows: Pr.79 > X12 > X66 > X65 > X16 > Pr.340.
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.

5.9.2 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.

The inverter starts up in the Network operation mode.
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 operation mode from the
10, 12
operation panel. If an instantaneous power failure
occurs when "12" is set, running is continued at the
condition before the instantaneous power failure.
