during
under
voltage
If the data could not be saved during activation of the under-voltage
protection function, the inverter displays the alarm code.
ErF
Yes
Retry function
When the inverter stops due to a trip, this function automatically resets
the inverter and restarts it.
(The number of retries and the latency between stop and reset can be
specified.)

Surge protection
Protects the inverter against surge voltages which might appear
between one of the power lines for the main circuit and the ground.

Protection against
momentary power
failure
Upon detection of a momentary power failure lasting 15 ms or more,
this function stops the inverter output.
If "restart after momentary power failure" is selected, this function
invokes a restart process when power has been restored within a
predetermined period.
—
—
Overload
prevention
control
In the event of overheating of the cooling fan or an overload condition
(alarm display: OH1 or O L U ), the output frequency of the inverter is
reduced to keep the inverter from tripping.

Mock alarm
A mock alarm can be generated with keypad operations to check the
failure sequence.
Err
Yes
(Note) No alarm output depending upon the data setting of the function code.
