(D) Operation command and frequency command Parameters
5 - 278
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.
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.

Tab. 5-106: Operation mode switching by signal X16
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 5-278.)
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.
