Overcurrent during
deceleration
Err03
1: The output circuit is grounded or short
circuited.
2: Motor auto-tuning is not performed.
3: The deceleration time is too 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: 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.
Overcurrent at
constant speed
Err04
1: The output circuit is grounded or short
circuited.
2: Motor auto-tuning is not performed.
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: 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.
Overvoltage
during
acceleration
Err05
1: The input voltage is too high.
2: An external force drives the motor during
acceleration.
3: The acceleration time is too short.
4: The braking unit and braking resistor are
not installed.
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.

3: The deceleration time is too short.
4: The braking unit and braking resistor are
not installed.
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.
