Problem Possible cause 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.
0012 EEPROM fault 1
･A data wiring error occurs. ･Turn off the inverter, then turn it again. If it
does not recover from the error, make a
service call.
0013 EEPROM fault 2
･ Power supply is cut off during
operation and data wiring is aborted.
･Turn the power off temporarily and turn it
back on, and then try
operation
again.
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.
0015 Main unit RAM fault
･The control RAM is defective. ･Make a service call.
0016 Main unit ROM fault
･The control ROM is defective. ･Make a service call.
0017 CPU fault 1
･The control CPU is defective. ･Make a service call.
0018 Remote control error
･An error arises during remote operation. ･Check the remote control device, cables,
etc.
001A Current detector fault
･The current detector is defective. ･Make a service call.
001B Optional current 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.
*
001D Low-current operation trip
･ The output current decreased to a
low-current detection level during
operation.
･Enable
(low-current detection).
･Check the suitable detection level for the
system (
, ).
･Make a service call if the setting is correct.
* 001E Under-voltage trip
(Main circuit)
･The input voltage (in the main circuit) is too
low.
･Check the input voltage.
･ Enable
(under-voltage trip
selection).
･To cope with a momentary stop due to
under-voltage, enable
(ride-through control) and
(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.
0054 Auto-turning error
･Check the motor parameter
to .
･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.
0029 Inverter type error
･Circuit board is changed.
(Or main circuit/drive circuit board)
･Make a service call.
* 0032 Brea in analog signal
cable
･The signal input via VIA is below the analog
signal detected level set with
.
･Check the cables for breaks. And check
the setting of input signal or setting value
of
.
0033 CPU communications
error
･A communications error occurs between
control CPUs.
･Make a service call.
0034 Excessive torque boosted
･The torque boost parameter
is set
too high.
･The motor has too small impedance.
･Decrease the setting of the torque boost
parameter
.
0035 CPU fault 2
･The control CPU is defective. ･Make a service call.
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.
