POSSIBLE CAUSES
1: The output circuit is earthed or short-
circuited.
2: Motor connection cable is too long.
3: IGBT overheating.
4: Internal connections are loose.
5: Main control board is defective.
6: The drive board is defective.
7: Inverter IGBT is defective.
1: The output circuit is earthed or short-
circuited.
2: Motor autotuning is not performed.
3: Acceleration time is too short.
4: Manual torque boost or V / F curve is
not suitable.
5: The voltage is too low.
6: The start-up operation is performed
on the rotating motor.
7: A sudden load is added during
acceleration.
8: The frequency converter model is of
too small a power class.
1: The output circuit is earthed or short-
circuited.
2: Motor autotuning is not performed.
3: Deceleration time is too short.
4: The voltage is too low.
5: A sudden load is added during
deceleration.
6: Braking unit and braking resistor are
not installed.

SOLUTIONS
1: Eliminate external faults.
2: Install reactor or outlet filter.
3: Check the air filter and cooling
fan.
4: Connect all cables correctly.
5: Request technical support
6: Request technical support
7: Request technical support
1: Eliminate external faults.
2: Perform auto-tuning of the
engine.
3: Increase the acceleration
time.
4: Adjust the manual torque
boost or V / F curve.
5: Adjust voltage to normal
range.
6: Select to restart the rotation
speed tracking or start the motor
after it stops.
7: Remove the added load.
8: Select a frequency converter
of a higher power class.
1: Eliminate external faults.
2: Perform auto-tuning of the
motor.
3: Increase deceleration time.
4: Adjust voltage to normal
range.
5: Eliminate added load.
6: Install the braking unit and
braking resistor.
