Operation mode selection

Pr.79 Operation mode selection
Used to select the operation mode of the inverter.
Mode can be changed as desired between operation using external
signals (external operation), operation from the PU (FR-DU07/FR-
PU07/FR-PU04), combined operation of PU operation and external
operation (external/PU combined operation), and network operation
(when RS-485 terminals or a communication option is used).

Specify the operation mode at power on (Pr.340)
⋅ When power is switched on or when power comes back on after
instantaneous power failure, the inverter can be started up in the
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 inverter
RS-485 terminals or communication option.
⋅ You can set the operation mode at power on (reset) according
to the Pr.79 and Pr.340 settings.

*1 The Pr.340 settings "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.
*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
and X65 signal.
