Auto-tuning error
 The motor parameter , ,
, ,  are not set
correctly.
 Set the left column parameters correctly
as a motor name plate and make an auto-
tuning again.

ETN3 0056
 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 rotating.  Make an auto-tuning again after the
rotation of the motor stops.

ETYP 0029 Inverter type error
 It may be a breakdown failure.  Contact your Toshiba distributor.

OC1 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 imput 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.
Ground fault trip
 A ground fault occurs in the output cable
or the motor.
 Check the cable and the motor for ground
faults.

OC2 0002 Overcurrent during
deceleration
 The deceleration time  is too short.  Increase the deceleration time .
Ground fault trip
 A ground fault occurs in the output cable
or the motor.
 Check the cable and the motor for ground
faults.

OC3 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).
Ground fault trip
 A ground fault occurs in the output cable
or the motor.
 Check the cable and the motor for ground
faults.

OCA 0005 Arm overcurrent at
start-up
 A main circuit elements is defective.  Contact your Toshiba distributor.

OCL 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

OH 0010 Overheat
 The cooling fan is life or fault
.
 The cooling fan requires replacement if it
does not rotate during operation.
Contact your Toshiba distributor.

 The ambient temperature is high or low
outside a specified ambient temperature.
 Operate at a specified ambient temperature
.

 The vent of the cooling fan is blocked up.  Secure sufficient space around the inverter.

 A heat generating device is installed
close to the inverter.
 Do not place any heat generating device
near the inverter.

 The load is large.  Reduce the load.
 Reduce f300: PWM carrier frequency.
 Set f316=1 (Carrier frequency with
automatic reduction).

 The temperature sensor is fault.
(Even if it resets after much time, When
always generating)
 Contact your Toshiba distributor.

OL1 000D Inverter overload
 The acceleration time ACC is too short.  Increase the acceleration time .

 The DC braking amount is too large.  Reduce the DC braking amount 
and the DC braking 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).

 The load is too large.  Use an inverter with a larger rating.
