POSSIBLE CAUSES
1: The output circuit is earthed or short-
circuited.
2: Motor auto-tuning is not performed.
3: The voltage is too low.
4: A sudden load is added during ope-
ration.
5: The frequency converter model is of
too small a power class.
1: The input voltage is too high.
2: An external force is driving the motor during
acceleration.
3: The acceleration time is too short.
4: Braking unit and braking resistor are not
installed.
1: The input voltage is too high.
2: An external force is driving the motor
during deceleration.
3: The deceleration time is too short.
4: Braking unit and braking resistor are
not installed.
1: The input voltage is too high.
2: An external force is driving the motor
during deceleration.
The input voltage is not within the
allowed range.

SOLUTIONS
1: Eliminate external faults.
2: Perform motor self-tuning.
3: Adjust voltage to normal range.
4: Eliminate added load.
5: Select a higher power class fre-
quency converter.
1: Adjust the voltage to the normal
range.
2: Cancel the external force or install
a braking resistor.
3: Increase the acceleration time.
4: Install the braking unit and braking
resistor.
1: The input voltage is too high.
2: An external force is driving the
motor during deceleration.
3: The deceleration time is too short.
4: Braking unit and braking resistor
are not installed 1: Adjust the voltage
to the normal range.
2: Cancel the external force or install
the braking resistor.
3: Increase the deceleration time.
4: Install the braking unit and braking
resistor.
1: Adjust the voltage to the normal
range.
2: Cancel the external force or install
the braking resistor.
Set the input voltage to the allowable
range.
