 Switching the operation mode by external signals (X65, X66 signals)
• When Pr.79 = "0, 2 or 6", the PU operation mode and External operation modes can be changed to the Network operation
mode during a stop (during motor stop, start command OFF) by the PU/NET operation switchover (X65) signal, or the
External/NET operation switchover (X66) signal. (When Pr.79 = "6", switchover is enabled during operation.)
• To switch between the Network operation mode and the PU operation mode
1.
Set Pr.79 = "0 (initial value) or 6".
2.
Set Pr.340 Communication startup mode selection = "10 or 12".
3.
Set "65" in any of Pr.178 to Pr.189 to assign the PU/NET operation switchover (X65) signal to a terminal.
4.
When the X65 signal is ON, the PU operation mode is selected. When the X65 signal is OFF, the NET operation
mode is selected.

When the X16 signal is OFF, the PU operation mode is selected. Also, when "0" is set for Pr.550 NET mode operation command source
selection and the communication option is not connected (communication option is the command source), the PU operation mode is selected.
When the X16 signal is ON, the External operation mode is selected.
• To switch between the Network operation mode and the External operation mode
1.
Set Pr.79 = "0 (initial value), 2, 6, 7". (When Pr.79 = "7" and the X12 (MRS) signal is ON, the operation mode can
be switched.)
2.
Set Pr.340 Communication startup mode selection = "0" (initial value), "1" or "2".
3.
Set "66" in one of Pr.178 to Pr.189 to assign the NET-External operation switching signal (X66) to a terminal.
4.
When the X66 signal is ON, the NET operation mode is selected. When the X66 signal is OFF, the External
operation mode is selected.
