Disconnected PU detection :
This function detects that the parameter unit (FR-PU04) has been
disconnected from the inverter for longer than 1s and causes the inverter to
provide an alarm output (PUE) and come to an alarm stop. When the PU has
been disconnected since before power-on, it is not judged as an alarm.
PU setting lock :
Control source of operation command, frequency command and parameter
setting is restricted to the operation panel or parameter unit (FR-PU04).
