Mitsubishi Electric FR-F740 EC Instruction Manual page 389

Parameter
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 op-
eration)
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.
0 (initial value)
X12 (MRS) ON
7
X12 (MRS) OFF
Tab. 6-46:
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 6-240.)
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.
