[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.

S3 terminal alarm
 Slide switch SW2 and parameter 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.

In forced operation
 “” 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).
 If the password is correct, pass is
displayed and if it is incorrect, fail is
displayed.
／

Switching display of
Easy setting mode / Standard setting
mode
 The EASY key was pushed in the
standard monitor mode.
 When easy is displayed, setting
mode becomes easy setting mode.
When std is displayed, it becomes
standard setting mode.

Note 2)
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 typ is set to 13, inverter return to
default setting.
 Set a region setting by using setting
dial.
Refer to section 3.1.

No trip of past trip
 No new record of past trip, after past trips
were clear.
 Normal operation.

No detailed information of past trip
 The detailed information of past trip is
read by pushing the center of setting dial
during blinking nerr ⇔ number.
 Normal operation.
To be returned by pressing MODE key.
Note 2)  is blinking after power supply is on. In this time, the keys are not operated.
But parameter set is lighting as same as other parameters and is not blinking.
