⋅ Depending on the Pr. 79 and Pr. 340 settings, the operation mode at power ON (reset) changes as described below.

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.
After the inverter has started up in the Network operation mode, parameter write and operation can be performed
from a program.
Set this mode for communication operation using the RS-485 terminals or communication option.

As set in Pr. 79.

1, 2

Started in Network operation mode.
When the setting is "2", it will resume the pre-instantaneous power 
failure operation mode after an instantaneous power failure occurs.

10, 12

Started in Network operation mode. Operation mode can be 
changed between the PU operation mode and Network operation 
mode from the operation panel. When the setting is "12", it will 
resume the pre-instantaneous power failure operation mode after 
an instantaneous power failure occurs.

The above parameters can be changed during a stop in any operation mode.

*1

This parameter allows its setting to be changed in any operation mode even if "0 (initial value) or 1" is set in Pr. 77 Parameter write selection.

*2

This parameter allows its setting to be changed in any operation mode even if "0 (initial value)" is set in Pr. 77 Parameter write selection.

*3

The parameters can be set whenever the communication option is connected. (Refer to page 308.).

The Pr. 340  setting "2" or "12" is mainly used for communication operation using the inverter RS-485 terminals. When a value other than "9999"

(selection of automatic restart after instantaneous power failure) is set in Pr. 57 Restart coasting time, the inverter will resume the same operation

state which was in before after power has been restored from an instantaneous power failure.

When Pr. 340 = "1, 10", a start command turns OFF if power failure has occurred and then restored during a start command is ON.

*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 

 key of the operation panel (FR-

DU07) and X65 signal.
