H:High Performance Functions
H01
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.)
H02 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 key. Press the
or key to confirm the history.

The new record of protective operation is stored in
the latest protective operation memory, and the
previous records are shifted one by one, and the
record of protective operation before the four
previous ones is deleted.
H03 Data initializing(Data reset)
This function restores (initializes) the factory
data over alterations made by the user.
Setting 0: Disabled
1: Initialize
Press the
STOP
and keys simultaneously
to change the setting to "1", then press the
key to initialize the settings of all functions. After
initialization is completed, the setting automatically
returns to "0".
H04
Auto-reset(Times)
H05 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.
H04
Set the number of resetting cycles of the
protective function.
Setting range: 0 to 10 (0: retry inactive)
H05
Set the wait time from activation of a protective
function to resetting.
Setting range: 2 to 20 s

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.
