[Alarm information]
Each message in the table is displayed to give a warning but does not cause the inverter to trip.
Error code Name Description Remedies

Output frequency upper limit 
An attempt was made to operate at a
frequency higher than 10 times the base
frequency (
 or  ).

Operate at a frequency within 10 times
the base frequency.

Operation panel key alarm 
The RUN or STOP key is held down for
more than 20 seconds.

The RUN or STOP key is faulty.

Check the operation panel.


f147
settings are different.

Match the settings of SW2 and
f147
.
Power supply OFF and ON after these
settings.

Auto-tuning

Auto-tuning in process

Normal if it the message disappears after
a few seconds.

Break in analog signal cable 
The signal input via VIC is below the
analog signal detection level set with

and setting value of

is
one or more.

Check the cables for breaks. And check
the setting of input signal or setting value
of

and

.

This alarm is cancelled, when operation
command is OFF after VIC input signal is
recovered.



“

” and operation frequency is
displayed alternately in operation of
forced fire-speed control.

It is normal the alarm is gone out after the
forced fire-speed control operation.

STO signal OFF 
STO terminal is in open-circuit.

Input voltage of STO terminal is low.

The voltage of P24 terminal decreases.

The load of P24 terminal (24Vdc power
supply) is over 100mA.

Control terminal block comes off.

Close STO and + SU circuit.

Check the load of P24 terminal, if STO
and +SU is shorted.

Check the load of P24 terminal.

Use P24 terminal up to 100mA including
transient current.

Install the control terminal block to the
inverter.


Password verification result 
After the password setting (
f738
), the
password was input to
f739
(password
verification).


Input requirement of region setting 
A region setting is not input yet.

Power supplied to the inverter at first time

As checking the region setting parameter
set is set to 0 , inverter return to default
setting.

As

read by pushing the center of setting dial
during blinking
nerr ⇔
number.

Normal operation.
To be returned by pressing MODE key.
