(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), "6" or "7".(At the Pr. 79 setting of "7", the operation mode can be switched when the X12
(MRS) signal turns on.)
2)Set "10" in Pr. 340 Communication startup mode selection.
3)Set "65" in any of Pr. 178 to Pr. 184 to 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.

(communication option control source) and the communication option is not fitted.
∗3
External operation mode when the X16 signal is on.
When switching between the network operation mode and external operation mode
1) Set Pr. 79 to "0 (initial value), 2, 6 or 7". (At the Pr. 79 setting of "7", the operation mode can be switched when the X12
(MRS) signal turns on.)
2) Set "0 (initial value) or 1" in Pr. 340 Communication startup mode selection.
3) Set "66" in any of Pr. 178 to Pr. 184 to assign the NET-PU operation switching signal (X66) to the terminal.
4) The operation mode changes to the network operation mode when the X66 signal turns on, or to the external
operation mode when the X66 signal turns off.

PU operation mode is selected when the X16 signal is off. When the X65 signal has been assigned, the operation mode changes with the ON/
OFF state of the X65 signal.
