Error code Failure code Problem Possible causes Remedies
*

0048 Over-torque /
Overcurrent fault

Power running torque or output current
reached f593 or more and maintain in
f595 during power running.

Enable  .

Reduce the load.

Check system error.
*

0049 Small-torque / Small
-current fault

Power running torque or output current
decreased
f593
or less and maintain
in f595 during power running.

Enable  .

Check system error.

The cooling fan does not rotate.

The fan requires replacement if it does
not rotate during operation.

The ambient temperature is too high.

Restart the operation by resetting the
inverter after it has cooled down enough.

The vent is blocked up.

Secure sufficient space around the inverter.

0010 Overheat

A heat generating device is installed close
to the inverter.

Do not place any heat generating device
near the inverter.

002E
Thermal fault stop
command from
external device

A thermal trip command (input terminal
function:  or  ) is issued by an
external control device.

The motor is overheated, so check
whether the current flowing into the motor
exceeds the rated current.

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.

If the emergency stop signal is input,
reset after releasing this signal.

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, contact
your Toshiba distributor.

0013 EEPROM fault 2  Power supply is cut off during

operation and data writing is aborted.
 The error occurred when various data
was written.
 Turn the power off temporarily and turn it
back on, and then try  operation
again.

Write the data again. Contact your
Toshiba distributor when it happening
frequently.

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, contact
your Toshiba distributor.

0015 Main unit RAM fault  The control RAM is defective.  Contact your Toshiba distributor.

0016 Main unit ROM fault  The control ROM is defective.  Contact your Toshiba distributor.

0017 CPU fault 1 
The control CPU is defective.

Contact your Toshiba distributor.

0018 Communication error 
The communication was broken off.

Check the remote control device, cables,
etc.

001A Current detector fault  The current detector is defective.  Contact your Toshiba distributor.

001B Optional unit fault 1  An optional unit has failed.
(such as a communication option)
 Check the connection of optional unit.

001C Remote keypad
disconnection fault

After run signal is activated by RUN key
of the remote keypad, disconnection is
occurred in 10 seconds or more.

In case the remote keypad is
disconnected, press STOP key before.

This fault is disabled by f731 = 1
setting.
*

001D Low-current
operation
fault
 The output current decreased to a low-
current detection level during operation.
 Enable

(low-current detection).

Check the suitable detection level for the
system (  ,  ,  ).
 Contact your Toshiba distributor if the
setting is correct.
*

001E Undervoltage fault
(main circuit)

The input voltage (in the main circuit) is
too low.

Check the input voltage.

Enable  (undervoltage trip
selection).

To take measures to momentary power
failure, set

=

, Regenerative
power ride-through control f302 and
Auto-restart control selection f301 .
* This marking trips can be selected valid or invalid by parameters.
