Possible Causes
1: The output circuit is grounded
or short circuited.
2: Motor auto-tuning is not
performed.
3: The deceleration time is too
Err03 short.
4: The voltage is too low.
5: A sudden load is added during
deceleration.
6: The braking unit and braking
resistor are not installed.
1: The output circuit is grounded
or short circuited.
2: Vector control is presented and
Motor auto-tuning is not
performed.
Err04
3: The voltage is too low.
4: A sudden load is added during
operation.
5: The AC drive model is of too
small power class.
1: The input voltage is too high.
2: An external force drives the
motor during acceleration.
Err05 3: The acceleration time is too
short.
4: The braking unit and braking
resistor are not installed.
1: The input voltage is too high.
2: An external force drives the
motor during deceleration.
Err06 3: The deceleration time is too
short.
4: The braking unit and braking
resistor are not installed.
1: The input voltage is too high.
Err07 2: An external force drives the
motor during deceleration.
1:The input voltage is not within
Err08
the allowable range.
Troubleshooting and Resolutions
1: Eliminate external faults.
2: Perform the motor auto-
tuning.
3: Increase the deceleration
time.
4: Adjust the voltage to
normal range.
5: Remove the added load.
6: Install the braking unit and
braking resistor.
1: Eliminate external faults.
2: Perform the motor
auto-tuning.
3: Adjust the voltage to
normal range.
4: Remove the added load.
5: Select an AC drive of
higher power class.
1: Adjust the voltage to
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: Adjust the voltage to
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
normal range.
2: Cancel the external force
or install the braking resistor.
1:Adjust the input voltage to
the allowable range.
