2.3.1 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 dealer.

Over-current during acceleration
Over-current flowing in element
during acceleration
･ The acceleration time
is too
short.
･The V/F setting is improper.
･A restart signal is input to the rotating
motor after a momentary stop, etc.
･A special motor (e.g. motor with a small
impedance) is used.
･Increase the acceleration time
.
･Check the V/F parameter.
･ Use
(Auto-restart) and
(ride-through control).
･Adjust the carrier frequency
.
･Set the carrier frequency control mode
selection parameter
to 1 or 3
(carrier frequency decreased
automatically).

0026
Over-current during deceleration
Over-current flowing in element
during deceleration
･ The deceleration time
is too
short.
･Increase the deceleration time .
･Set the carrier frequency control mode
selection parameter
to 1 or 3
(carrier frequency decreased
automatically).
0003
0027
Over-current during constant
speed operation
Over-current flowing in element
during operation
･The load fluctuates abruptly.
･The load is in an abnormal condition.
･Reduce the load fluctuation.
･Check the load (operated machine).
･Set the carrier frequency control mode
selection parameter
to 1 or 3
(carrier frequency decreased
automatically).

Ground fault trip
Arm over-current at start-up.
(for 11 and 15 kW models only)
･A current leaked from an output cable
or the motor to ground.
･A main circuit elements is defective.
･Check the cables, connectors, and so
on for ground faults.
･Make a service call.
0004 Over-current (An over-current
on the load side at start-up)
･The insulation of the output main circuit
or motor is defective.
･The motor has too small impedance.
･ A 11 or 15kW model was started,
although a current is leaked from an
output cable or the motor to ground.
･ Check the cables and wires for
defective insulation.
･When using a 11 or 15kW model,
check cables, connectors, and so on for
ground faults.
0005 Arm over-current at start-up.
･A main circuit elements is defective. ･Make a service call.
* 0008 Input phase failure
･A phase failure occurred 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.
･ Enable (input phase failure
detection).
･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.
･ Enable
(output phase failure
detection).
* You can select a trip ON/OFF by parameters.
