- Trip information and remedies
13.1 Trip /Alarm causes 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 Problem Possible causes 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 setting.
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, 7, decrease vb.
In case of pt=2 to 6, set f415
(Motor rated current) and make an auto-
tuning.
Low inductance motor especially High
speed motor is used.
Choose the higher power range drive.
(1 class up drive is recommended.)
0002
Overcurrent during
deceleration
The deceleration time is too short. Increase the deceleration time .
Low inductance motor especially High
speed motor is used.
Choose the higher power range drive.
(1 class up drive is recommended.)
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).
Low inductance motor especially High
speed motor is used.
Choose the higher power range drive.
(1 class up drive is recommended.)
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 Overcurrent at start-
up
A main circuit element 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.
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.
Check the main circuit output line, motor,
etc. for phase failure.
Select output phase failure detection
parameter f605.
000A Overvoltage during
acceleration
The input voltage fluctuates abnormally.
(1) The power supply has a capacity of
500kVA 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).
* This marking trips can be selected valid or invalid by parameters.
