INVERTER SETTING
(2) Operation mode switching by the PU operation interlock signal (X12)
PU operation interlock is a function that forcefully changes the operation mode to the Network operation
mode at turn-OFF of the X12 signal (Bit 11), which gives operation commands through FL remote
communication.
This function prevents the operation mode from being accidentally unswitched from the PU operation
mode. If the operation mode left unswithced from the PU operation mode, the inverter does not reply to the
commands sent through FL remote communication.
