Selection of operation mode and operation location
Switching of operation mode by external terminal (X65, X66)
When Pr. 79 = any of "0, 2, 6", 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 oper-
ation)
When switching from network operation mode to PU operation mode:
Set Pr. 79 to "0" (initial value) or "6".
Set "10" in Pr. 340.
Set "65" to any of Pr. 178 to Pr. 182 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.
