*Enable/Disable can be selected for trip with a parameter.
Detection factor
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) 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>.
The motor parameter does not match the
motor characteristic.
The setting on <vL: Base frequency 1> or
<F417: Motor rated speed> does not
match the motor rating.
1) Internal error exists.
2) Replaced the printed circuit board
(contact your Toshiba distributor for
replacing the printed circuit board).
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) 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.

Measures
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.
1) and 2) Check that the motor is
connected.
3) Set <F417> according to the motor
rating.
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.
Set <vL: Base frequency 1> or <F417:
Motor rated speed> according to the
motor rating.
1) Error in internal inverter.
Contact your Toshiba distributor.
2) Set <tyP: Default setting> = "6: Initialize
typeform".
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.
1) Increase the deceleration time. <dEC:
Deceleration time 1>, etc.
2) Change the inverter to large capacity.
