(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" in any of Pr. 178 to Pr. 189 (input terminal function selection) to
assign the function.

REMARKS
⋅ The operation mode status changes depending on the setting of Pr. 340 Communication startup mode selection and the ON/OFF
states of the X65 and X66 signals. (For details, refer to page 188.)
⋅ The priorities of Pr. 79, Pr. 340 and signals are Pr. 79 > X12 > X66 > X65 > X16 > Pr. 340.
CAUTION
⋅ Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Please
make setting after confirming the function of each terminal.
