Selection of operation mode and operation location Parameter
6 - 424
Switching of operation mode by external terminal (X16)
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 switch-over mode can be changed during oper-
ation)
For the terminal used for X16 signal input, set "16" to any of Pr. 178 to Pr. 189 "Input terminal
function selection" to assign the function.

Tab. 6-121: Operation mode switching by signal X16
NOTES The operation mode status changes depending on the setting of Pr. 340 "Communication
start-up mode selection" and the ON/OFF states of the X65 and X66 signals. (For details,
refer to page 6-425.)
The priorities of Pr. 79, Pr. 340 and signals are:
Pr. 79 > X12 > X66 > X65 > X16 > Pr. 340
Changing the terminal assignment using Pr. 178 to Pr. 189 "Input terminal function selec-
tion" may affect the other functions. Please make setting after confirming the function of
each terminal.
