Error code Failure code Problem Possible causes Remedies
QJ 002E External thermal trip • An external thermal trip is input. • Check the external thermal input.
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 Remote control error • An error arises during remote operation. • Check the remote control device, cables,
etc.
GTT 001A Current detector fault • The current detector is defective. • Make a service call.
GTT 001B Optional circuit board
format error • An optional circuit board in a different
format is installed.
• Check again to be sure that the circuit
board is connected correctly, and then
reset the power supply.
• Replace the circuit board with a correctly
formatted one.
*
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 (ride-
through control) 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.
• 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.
