[E0.45] decides the restart behavior after power loss:
If option 1 is selected, then converter will run automatically when AC power re-
sumes, if the run command source is set to 'panel'.
If option 2 is selected, then converter will run automatically when AC power re-
sumes, if the run command source is set to 'multi-function digital input'.
The power loss restart procedure will be performed after [E0.46] 'Power loss re-
start delay'.
●
If the frequency converter was running in 3-wire mode before
power loss, the restart of the frequency converter is decided by
the status of this 3-wire terminal after power on.
●
If the power loss was caused by power supply interference, an
error code 'UE-1' will be displayed on the operating panel in un-
dervoltage situation, and the frequency converter will not restart
automatically after power on even setting [E0.45] is 'Active'.
●
If the run command is from communication, the frequency con-
verter ONLY restarts after sending a stop command first and then
sending a run command by communication.
●
When E0.45 select "1" or "2", if the power supply of frequency
converter and the error "UE-1" recover within the time of [E9.01],
the frequency converter will restart; if the error "UE-1" always ex-
ists during the time of [E9.01], the frequency converter will not
restart.
