Selection of operation mode
(2)
Network operation mode (Pr. 79 setting "0" (initial value), "2")
Select the Network operation mode to give start and frequency commands via CC-Link communication.
Generally, parameter change cannot be performed from the operation panel in the Network operation mode. (Some
parameters can be changed. Refer to the detailed description of each parameter.)
When "0" (initial value) is selected for Pr. 79, the inverter enters the Network operation mode at power-ON.
When frequent parameter changing is necessary, setting "0" (initial value) allows the operation mode to be changed easily
to the PU operation mode by pressing
return to the Network operation mode.
Pr. 79 = "2" sets the Network operation mode to be always selected at power-ON and disables the operation mode change.
(3)
PU operation mode (Pr. 79 setting "1")
(4)
Switch-over mode (Pr. 79 setting "6")
While continuing operation, you can switch between the PU operation and the Network operation (CC-Link communication).

Send the mode change command to the Network operation mode through CC-Link communication.
(Rotation direction and set frequency are the same as those of PU operation.)
Select the PU operation mode with the operation panel.
(The rotation direction and frequency command in the Network operation mode are used unchanged.)

Select the PU operation mode when applying start and
frequency command by only the key operation of the
operation panel. Also select the PU operation mode when
making communication using the PU connector.
When "1" is selected for Pr. 79, the inverter enters the PU
operation mode at power ON. You cannot change to the
other operation mode.
The setting dial of the operation panel can be used for
setting like a potentiometer. (Refer to Pr. 161 Frequency
setting/key lock operation selection (page 224))
