Name
 An attempt was made to operate at a
frequency higher than 10 times the base
frequency ( or ).
 The RUN or STOP key is held down for
more than 20 seconds.
 The RUN or STOP key is faulty.
 Slide switch SW2 and parameter f147
settings are different.
 Auto-tuning in process
 The signal input via VIC is below the
analog signal detection level set with
 and setting value of  is
one or more.
 "" and operation frequency is
displayed alternately in operation of
forced fire-speed control.
 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.
 After the password setting (f738), the
password was input to f739 (password
verification).
 The EASY key was pushed in the
standard monitor mode.
 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.
 No new record of past trip, after past trips
were clear.
 The detailed information of past trip is
read by pushing the center of setting dial
during blinking nerr ⇔ number.

Remedies
 Operate at a frequency within 10 times
the base frequency.
 Check the operation panel.
 Match the settings of SW2 and f147.
Power supply OFF and ON after these
settings.
 Normal if it the message disappears after
a few seconds.
 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.
 It is normal the alarm is gone out after the
forced fire-speed control operation.
 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.
 If the password is correct, pass is
displayed and if it is incorrect, fail is
displayed.
 When easy is displayed, setting
mode becomes easy setting mode.
When std is displayed, it becomes
standard setting mode.

Set a region setting by using setting
dial.
Refer to section 3.1.
 Normal operation.
 Normal operation.
To be returned by pressing MODE key.
