2.21 Communication operation
2.21.1 Operation mode selection [Pr. 79, 340]
(common)
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.
The above parameters can be changed during a stop in any operation mode.
*1
However, the parameters can be set whenever the communication option is connected. Changed setting value is valid when
powering on or resetting the inverter.
(1) Operation mode at power-on [
Pr. 340
]
*1
Setting values 2 and 12 for [Pr.340] are available only for
. These setting values are mainly used in a communication
operation with RS-485 terminal. When [
Pr. 57 Restart coasting time 9999
] (automatic restart after instantaneous power failure is
selected) , 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
key of the control
panel (PU07) and X65 signal.
