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.
