Problem
Output frequency  An attempt was made to operate at a
upper limit
frequency higher than 10 times the base
frequency ( or ).
Operation panel key  The RUN or STOP key is held down for
alarm more than 20 seconds.
 The RUN or STOP key is faulty.
S3 terminal alarm  Slide switch SW2 and parameter f147
settings are different.
Auto-tuning  Auto-tuning in process
Break in analog  The signal input via VIC is below the
signal cable analog signal detection level set with
 and setting value of  is
one or more.
In forced operation  "" and operation frequency is
displayed alternately in operation of forced
fire-speed control.
STO signal OFF  STO terminal is in open-circuit.
Password verification  After the password setting (f738), the
result
password was input to f739 (password
verification).
Switching display of  The EASY key was pushed in the
Easy setting mode /
standard monitor mode.
Standard setting
mode
Input requirement of  A region setting is not input yet.
region setting
 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 trip of past trip  No new record of past trip, after past trips
were clear.
No detailed  The detailed information of past trip is
information of past
read by pushing the center of setting dial

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 .
 It is normal the alarm is gone out after the
forced fire-speed control operation.
 Close STO and + SU circuit.
 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.
