Problem
Possible causes
Remedies
*
GRJ
0008
Input phase failure
•
A phase failure occurred in the
input line of the main circuit.
•
The inverter may trip because of
GRJ
if switching between
acceleration and deceleration is
done in succession at intervals
of less than 1 second.
•
Check the main circuit input line
for phase failure.
•
Enable
H
(input phase
failure detection). Set the
H
parameter to 0.
QJ
0010
Overheat
•
The cooling fan does not rotate.
•
The ambient temperature is too
high.
•
The vent is blocked up.
•
A heat generating device is
installed close to the inverter.
•
The thermistor in the unit is
broken.
•
Restart the operation by
resetting the inverter after it has
cooled down enough.
•
The fan requires replacement if
it does not rotate during
operation.
•
Secure sufficient space around
the inverter.
•
Do not place any heat-
generating device near the
inverter.
•
Make a service call.

WR
001E
Undervoltage trip
(main circuit)
•
The input voltage (in the main
circuit) is too low.
•
Check the input voltage.
•
Enable
H
(undervoltage
trip selection).
•
To cope with a momentary stop
due to undervoltage, enable
H
(ride-through control)
and
H
(auto-restart).
GH
0022
Ground fault trip
Arm overcurrent
•
A ground fault occurs in the
output cable or the motor.
•
A main circuit element is
defective.
•
Check the cable and the motor
for ground faults.
•
Make a service call.
G
0011
Emergency stop
•
During automatic operation or
remote operation, a stop
command is entered from the
operation panel or a remote
input device.
•
Reset the inverter.
GTT
0015
Main unit RAM fault
•
The control RAM is defective.
•
Make a service call.
GTT
0016
Main unit ROM fault
•
The control ROM is defective.
•
Make a service call.
GTT
0017
CPU fault trip
•
The control CPU is defective.
•
Make a service call.
GTT
0018
Remote control
error
•
An error arises during remote
operation.
•
Check the remote control
device, cables, etc.
GTT
001A
Current defector
fault
•
The current detector is defective.
•
Make a service call.
GGR
0012
EEPROM fault 1
•
A data writing error occurs.
•
Turn off the inverter, then turn it
on again. If it does not recover
from the error, make a service
call.
GGR
0013
EEPROM fault 2
•
Power supply is cut off during
V[R
operation and data
writing is aborted.
•
Turn the power off temporarily
and turn it back on, and then try
V[R
operation again.
GGR
0014
EEPROM fault 3
•
A data writing error occurs.
•
Turn off the inverter, then turn it
on again. If it does not recover
from the error, make a service
call.
*
G
0032
Break in analog
signal cable
•
The signal input via VI/S3 is
below the analog signal
detection level set with
H
.
•
Check the cables for breaks
and change the setting of
H
if no breaks are found.
