Mitsubishi Electric FR-F740 EC Instruction Manual page 390

Selection of operation mode and operation location
Switching of operation mode by external terminal (X65, X66)
When Pr. 79 = any of "0, 2, 6, 7", the operation mode switching signals (X65, X66) can be used
to change the PU or external operation mode to network operation mode during a stop (during
a motor stop or start command off). (Pr. 79 = 6 switch-over mode can be changed during op-
eration)
When switching between the network operation mode and PU operation mode:
Set Pr. 79 to "0" (initial value), "6" or "7". (At the Pr. 79 setting of "7", the operation mode
can be switched when the X12 (MRS) signal turns on.)
Set "10" or "12" in Pr. 340 "Communication start-up mode selection".
Set "65" to any of Pr. 178 to Pr. 189 to assign the PU-NET operation switching signal (X65)
to the external terminal.
The operation mode changes to PU operation mode when the X65 signal turns on, or to
network operation mode when the X65 signal turns off.
