Total operation time
•
The total power-on time of the inverter is
displayed.
A number between 0 and 6500 is displayed,
indicating 0 to 65000 hours. (The time is
displayed in ten hours, though the inverter
counts each hour. The time shorter than one
hour is not counted.)
Trip history
•
A history of the latest four events of activation
of protective functions is stored in
memory. To call up each event, press the I
key. Press the or key to confirm the

Data initializing (Data reset)
•
This function restores (initializes) the factory
data over alterations made by the user.
Setting 0: Disabled
1: Initialize
Press the and keys simultaneously to
change the setting to "1", then press the key
to initialize the settings of all functions. After
H03
initialization is completed, the setting
automatically returns to "0".
Auto-reset (Times)
Auto-reset (Reset interval)
When the protective function of the inverter
which starts the retry function is activated,
operation of the inverter protective function is
canceled to restart the inverter automatically
instead of an alarm and output stop.
•
Set the number of resetting cycles of the
protective function.
Setting range: 0 to 10 (0: retry inactive)
•
Set the wait time from activation of a
protective function to resetting.

DATA
•
When the data of H04 Retry (Times) is set to
1 to 10, retry operation starts and the time set
at H05 "Retry (Reset interval)" elapses, then
an inverter start command is automatically
input. If the cause of the alarm has been
removed, the inverter starts without entering
the alarm mode. If the cause of the alarm
remains, the protective function is activated
again to wait for the time set at H05 "Retry
(Times)". If the cause of the alarm is not
removed after the number of repetition cycles
set at H04 "Retry (Reset interval)", the
inverter enters the alarm mode.
WARNING
If the retry function has been
selected, the inverter may automatically
restart according to some causes after
tripping. (Design the machine so that human
safety is ensured after restarting.)
Otherwise an accident could occur.
