Fault code
Fault type
Reason
Solution
Err01
Output
short-circuit fault
1.Short-circuit phenomena exists
in AC Drive output
1. Ask for technical service
Err02
Overcurrent during
acceleration
1. The output circuit of AC
Drive is grounded or short
circuited.
2. The acceleration time is too
short.
3. The startup operation is
performed on the rotating motor.
4. The AC Drive model is of too
small power.
1. Eliminate external faults.
2. Increase the acceleration time.
3. Select rotational speed tracking
restart or start the motor after it
stops.
4. Select the AC Drive of higher
power.
Err03
Overcurrent during
deceleration
1. The output circuit of AC
Drive is grounded or short
circuited.
2. The deceleration time is too
short.
1. Eliminate external faults.
2. Increase the deceleration time.
Err04
Overcurrent at
constant speed
1. The output circuit of AC
Drive is grounded or short
circuited.
2. The AC Drive model is of too
small power.
1. Eliminate external faults.
2. Select the AC Drive of higher
power.
Err05
Overvoltage during
acceleration
1. Input voltage abnormal.
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. Turn the input power to the
normal range.
2. Cancel the external force.
3. Increase the acceleration time.
4. Installed the braking unit and
braking resistor.
Err06
Overvoltage during
deceleration
1. Input voltage abnormal.
2. An external force drives the
motor during deceleration.
3. The deceleration time is too
short.
4. The braking unit and braking
resistor are not installed.
1. Turn the input power to the
normal range.
2. Cancel the external force.
3. Increase the deceleration time.
4. Installed the braking unit and
braking resistor.
Err07
Overvoltage at
constant speed
1. Input voltage abnormal.
2. An external force drives the
motor during deceleration.
1. Turn the input power to the
normal range.
2. Cancel the external force.
Err08
Buffer resistance
overload
1. The input voltage is not
within the allowable range.
1. Adjust the input voltage to the
allowable range.
Err09
Undervoltage
1. Instantaneous power failure
occurs on the input supply.
2. The input voltage is not
within the normal range.
3. The AC Drive has an
1. Reset the fault.
2. Adjust the input voltage to
normal range.
3. Looking for technical service.
