Parameters
Switching operation mode by external signal (X16 signal)
● When External operation and the operation from the operation panel are used together, the PU
operation mode and External operation mode can be switched during a stop (during motor stop,
start command OFF) by using the PU-External operation switchover signal (X16).
● When Pr. 79 = "0", "6" or "7", switching between the PU operation mode and External operation
mode is possible. (When Pr. 79 = "6", the switchover can also be made during operation.)
● To input the X16 signal, set "16" in any of Pr. 178 to Pr. 189 (input terminal function selection) to
assign the function to a terminal.

Tab. 5-54:
NOTES The status of the operation mode follows the Pr. 340 "Communication startup mode selection"
setting and the ON/OFF state of the X65 and X66 signals. (For details, refer to page 5-123.)
The priority among Pr. 79 and Pr. 340 and signals is Pr. 79 > X12 > X66 > X65 > X16 > Pr. 340.
Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may
affect the other functions. Set parameters after confirming the function of each terminal.
Switching the operation mode by external signals (X65, X66 signals)
● When Pr. 79 = "0, 2 or 6", the PU operation mode and External operation mode 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, 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
Set Pr. 79 = "0 (initial value) or 6".
Set Pr. 340 "Communication startup mode selection" = "10 or 12".
Set "65" in any of Pr. 178 to Pr. 189 to assign the NET-PU operation switching signal(X65) to a
terminal.
When the X65 signal is ON, the PU operation mode is selected. When the X65 signal is OFF, the
Network operation mode is selected.
