Error code Failure code Problem Possible causes Remedies

The motor parameter  ,  ,  ,
 ,  are not set correctly.

Set the left column parameters correctly
as a motor name plate and make an auto-
tuning again.

Set parameter f416 to smaller 70% of
the present value, and execute the auto-
tuning again.

The motor with the capacity of 2 classes
or less than the inverter is used.

The output cable is too thin.

The inverter is used for loads other than
those of three-phase induction motors.

Set the left column parameters correctly
as a motor name plate and make an auto-
tuning again.
 Then set
f400
=
1
, when trip occurs.

The motor is not connected.

Connect the motor.

Check whether the secondary magnetic
contactor.

The motor is rotating.

Make an auto-tuning again after the
rotation of the motor stops.

is set and High speed
motor is connected.

Choose the higher power range drive.
(1 class up drive is recommended.)

A ground fault occurs in the output cable
or the motor.

Check the cable and the motor for ground
faults.
 Overcurrent of dynamic braking resistor  Increase the deceleration time
dec
.
 Set the supply voltage correction
f307
to 1 or 3 .

0022 Ground fault

When inverters are fed by AC power
supply and connected with common DC
bus link, unnecessary trip occurs.

Set the parameter f614 to 0
“Disabled”.


002F Step-out (for PM
motor drive only) 
The motor shaft is locked.
 One output phase is open.

An impact load is applied.

Using the DC braking function.

Unlock the motor shaft.
 Check the interconnect cables between
the inverter and the motor.

Prolong the acceleration / deceleration
time.

Turn off the Step-out function when using
the DC braking function or change the DC
braking to Servo lock function.

0029 Inverter type error 
It may be a breakdown failure.

Contact your Toshiba distributor.

002D Over speed fault  The input voltage fluctuates abnormally.
 Over speed fault due to the overvoltage
limit operation.
 Check the input voltage.
 Install an optional dynamic braking
resistor. (optional)


0032 Analog input break
detection fault 
The input signal from VIC is equal to or
less than the  setting.

Check the VIC signal cable for breaks.
Also, check the input signal value or
setting of
 .

0033 CPU communications
error
 A communications error occurs between
control CPUs.
 Contact your Toshiba distributor.

0034 Over torque boost
fault

The automatic torque boost parameter

setting is too high.

The motor has too small impedance.

Set a lower automatic torque boost
parameter

setting.

Make an auto-tuning.

0035 CPU fault 2 
The control CPU is defective.

Contact your Toshiba distributor.

0037 Optional unit fault 2 
An optional device is defective.

Contact your Toshiba distributor.

003A CPU fault 3 
The control CPU is defective.

Contact your Toshiba distributor.

0057 Internal circuit fault  Internal circuit is defective.  Contact your Toshiba distributor.

0040 PTC fault  PTC thermal protection is occurred.  Check the PTC in motor.

0045 Servo lock fault 
The motor shaft is not locked in servo lock
operation.

Reduce the load in servo lock operation.
