[30A,B,C]
T
uning error *1
Stops the inverter output when a tuning failure, interruption, or
abnormal tuning result is detected during tuning of motor
parameters.
Er7 Yes

com
munication
error
Upon detection of an RS-485 communications error, the inverter
stops its output.
Er8 Yes
Da

d
uring 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.)

S
urge protecti
on
Protects the inverter against surge voltages which might appear
between one of the power lines for the main circuit and the ground.

entary
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.

control
In the event of overheating of the cooling fan or an overload
condition (alarm display: OH1
or OLU), the output frequency
of the inverter is reduced to keep the inverter from tripping.
