Problem

Possible causes

Remedies

002E

External thermal trip

• An external thermal trip is input.

• Check the external thermal input.

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).

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.

0033

CPU
communications
error

• A communications error occurs between

control CPUs.

• Make a service call.

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.

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.
