Error code Failure code Problem Possible causes Remedies
QJ
002E External thermal trip
An external thermal trip is input.
PTC protection worked.
Check the external thermal input.
Check the PTC in the motor.
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.
GGR
0012 EEPROM fault 1
A data writing error occurs. Turn off the inverter, then turn it 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 reading error occurred. Turn off the inverter, then turn it again. If it
does not recover from the error, make a
service call.
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 1
The control CPU is defective. Make a service call.
*
GTT
0018 Communication error
An error arises during serial
communication.
Check the remote control device, cables,
etc.
GTT
001A Current detector fault
The current detector is defective. Make a service call.
GTT
001B Network error
The error was occurred during Network
communication.
Check the Network device and wiring.
*
WE
001D Low-current
operation
Trip
The output current decreased to a low-
current detection level during operation.
Enable H (low-current detection).
Check the suitable detection level for the
system (H, H).
Make a service call if the setting is
correct.
*
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 (coast stop)
and H (auto-restart).
GH
0022 Ground fault trip
A ground fault occurs in the output cable
or the motor.
Check the cable and the motor for ground
faults.
GVP
0054 Auto-tuning error
Check the motor parameter H to H.
The motor with the capacity of 2 classes or less than the inverter is used.
The output cable is too thin.
The motor is rotating.
The inverter is used for loads other than those of three-phase induction motors.
GV[R
0029 Inverter
type error
Circuit board is changed.
(Or main circuit/drive circuit board)
Make a service call.
*
G
0032 Brea in analog signal
cable
The signal input via VIA is below the
analog sinal detectio level set with
H.
Check the cables for breaks. And check
the setting of input signal or setting value
of H.
G
0033 CPU
communications
error
A communications error occurs between
control CPUs.
Make a service call.
G
0034 Excessive torque
boosted
The torque boost parameter H is
set too high.
The motor has too small impedance.
Re do the Auto-tuning then set H.
Decrease the setting of the torque boost
parameter H.
G
0035 CPU fault 2
The control CPU is defective. Make a service call.
UQWV
002F Step-out
(For PM motor only)
The motor shaft is locked.
One output phase is open.
An impact load is applied.
Unlock the motor shaft.
Check the interconnect cables between
the inverter and the motor.
* You can select a trip ON/OFF by parameters.
