Selection of operation mode and operation location
(10) Switching of operation mode by external signal (X16 signal)
When external operation and operation from the operation panel are used together, use of the PU-External operation
switching signal (X16) allows switching between the PU operation mode and External operation mode during a stop
(during a motor stop, start command OFF).
When Pr.79 = any of "0, 6, 7", the operation mode can be switched between the PU operation mode and External
operation mode. (Pr.79 = "6" At Switchover mode, operation mode can be changed during operation)
For the terminal used for X16 signal input, set "16" to any of Pr.178 to Pr.184 (input terminal function selection) to assign the
function.
(11) Switching of operation mode by external signals (X65, X66 signals)
When Pr.79 = any of "0, 2, 6, 7", the operation mode switching signals (X65, X66) can be used to change the PU or
External operation mode to the Network operation mode during a stop (during a motor stop or start command OFF).
(Pr.79 = "6" Switch-over mode can be changed during operation)
When switching between the Network operation mode and PU operation mode
1)Set Pr.79 to "0" (initial value) or "6".
2)Set "10" in Pr.340 Communication startup mode selection
3)Set "65" in any of Pr.178 to Pr.184to assign the NET-PU operation switching signal (X65) to the terminal.
4)The operation mode changes to the PU operation mode when the X65 signal turns ON, or to the Network operation
mode when the X65 signal turns OFF.

REMARKS
The operation mode status changes depending on the setting of Pr.340 Communication startup mode selection and the ON/OFF
status of the X65 and X66 signals. (For details, Refer to page 192)
The priorities of Pr.79 , Pr.340 and signals are Pr.79 > X12 > X66 > X65 > X16 > Pr.340.
NOTE
Changing the terminal assignment using Pr.178 to Pr.184 (input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.
