Etn 0028 Auto-tuning
error
1) The motor parameter does not match
the motor characteristic.
2) Executed auto-tuning while the motor is
rotating.
3) The output frequency does not increase
within few minutes.
1) Set the motor parameters according to
the motor characteristic.
<vL: Base frequency 1>,
<vLv: Base frequency voltage>,
<F405: Motor rated capacity>,
<F415: Motor rated current>,
<F417: Motor rated speed>, etc.
2) Check that the motor is stopped, and
perform auto-tuning again.
3) Check that the motor is not stopped
while the output frequency is risin on
the system.
Etn1 0054 Auto-tuning
error 1
1) The motor is not connected.
2) Something other than the motor is
connected.
3) In the induction motor, an improper
value, a synchronized motor speed
value or a value close to it is set in
<F417: Motor rated speed>.
1) and 2) Check that the motor is
connected.
3) Set <F417> according to the motor
rating.
Etn2 0055 Auto-tuning
error 2
The motor parameter does not match the
motor characteristic.
Set the motor parameters according to the
motor characteristic.
<vL: Base frequency 1>,
<vLv: Base frequency voltage>,
<F405: Motor rated capacity>,
<F415: Motor rated current>,
<F417: Motor rated speed>, etc.
Etn3 0056 Auto-tuning
error 3
The setting on <vL: Base frequency 1> or
<F417: Motor rated speed> does not
match the motor rating.
Set <vL: Base frequency 1> or <F417:
Motor rated speed> according to the
motor rating.
EtyP 0029 Inverter type
error
1) Internal error exists.
2) Replaced the printed circuit board
(contact your Toshiba distributor for
replacing the printed circuit board).
1) Error in internal inverter.
Contact your Toshiba distributor.
2) Set <tyP: Default setting> = "6: Initialize
typeform".
OC1 0001 Overcurrent
(during
acceleration)
1) The acceleration time is short.
2) <Pt: V/f Pattern> does not match the
machinery.
3) Momentary power failure occurred, and
tried to start the rotating motor.
4) Tried to run the special motor
(impedance small).
5) Tried to run a low inductance motor like
a high-speed motor.
6) When <Pt> = "11", polarity of PG is
opposite.
7) When <F614: Pulse width of short
circuit detection at start> = "0", and
<F613>=2, or 3, inverter output short
circuit.
1) Increase the acceleration time. <ACC:
Acceleration time 1>, etc.
2) Set <Pt: V/f Pattern> according to the
machinery.
3) Set <F301: Auto-restart>. Depending
on the characteristic of machinery,
<F302: Regenerative power ride-
through> = "1" is also effective.
4) When <Pt> is set to "0", "1", "2", or "7",
lower <vb: Manual torque boost 1>.
For settings other than "0", "1", "2", or
"7", perform auto-tuning with <F400:
Offline auto-tuning>. <F402: Automatic
torque boost> is set matching the
motor.
5) Change the inverter to large capacity.
OC2 0002 Overcurrent
(during
deceleration)
1) The deceleration time is short.
2) Tried to run a low inductance motor like
a high-speed motor.
3) When <Pt> = "11", polarity of PG is
opposite.
4) When <F614: Pulse width of short
circuit detection at start> = "0", and
<F613>=2, or 3 inverter output short
circuit.
1) Increase the deceleration time. <dEC:
Deceleration time 1>, etc.
2) Change the inverter to large capacity.
*Enable/Disable can be selected for trip with a parameter.
