13. Before Contacting your Toshiba distributor
- Trip information and remedies
13.1 Trip causes/warnings and remedies
When a problem arises, diagnose it in accordance with the following table.
If it is found that replacement of parts is required or the problem cannot be solved by any remedy described in the
table, contact your Toshiba distributor.
[Trip information]
Error code Failure code Name Description Remedies

0001 Overcurrent during
acceleration
 The acceleration time  is too short.  Increase the acceleration time .
 The V/F setting is improper.  Check the V/F parameter.
 A restart signal is input to the rotating
motor after a momentary stop, etc.
 Use  (auto-restart) and 
(ride-through control).
 A special motor (e.g. motor with a small
impedance) is used.
 In case of pt=0, 1, decrease vb.
 In case of pt=2, 3, 4, set f415
(Motor rated current) and make an auto-
tuning.
 The cable length to a motor is long.  AC reactors etc. are required for the
output side. (Refer to section 1.4.3-(4))

0002 Overcurrent during
deceleration
 The deceleration time  is too short.  Increase the deceleration time .
 The cable length to a motor is long.  AC reactors etc. are required for the
output side. (Refer to section 1.4.3-(4))

0003 Overcurrent during
constant speed
operation
 The load fluctuates abruptly.
 The load is in an abnormal condition.
 Reduce the load fluctuation.
 Check the load (operated machine).
 The cable length to a motor is long.  AC reactors etc. are required for the
output side. (Refer to section 1.4.3-(4))

0004 Overcurrent (An
overcurrent on the
load side at start-up)
 The insulation of the output main circuit or
motor is defective.
 The motor has too small impedance.
 Check the secondary wiring and insulation
state.
 Set f613=2, 3

0005 Arm overcurrent at
start-up
 A main circuit elements is defective.  Contact your Toshiba distributor.
*

0008 Input phase failure
 A phase failure occured in the input line of
the main circuit.
 The capacitor in the main circuit lacks
capacitance.
 Check the main circuit input line for phase
failure.
 Set input phase failure detection selection
f608=0.
 Check the capacitor in the main circuit for
exhaustion.
*

0009 Output phase failure
 A phase failure occurred in the output line
of the main circuit.
 The motor has too big impedance.
 Check the main circuit output line, motor,
etc. for phase failure.
 Set output phase failure detection
selection f605=0.

000A Overvoltage during
acceleration
 The input voltage fluctuates abnormally.
(1) The power supply has a capacity of
200kVA or more.
(2) A power factor improvement capacitor is
opened or closed.
(3) A system using a thyristor is connected
to the same power distribution line.
 Insert a suitable input reactor.
 A restart signal is input to the rotating
motor after a momentary stop, etc.
 Use  (auto-restart) and 
(ride-through control).
* You can select a trip ON/OFF by parameters.
