Error
messages
Defect type Possible causes Solutions
Err.01
Protection unit
of the inverter
1. Short circuit in output inverter
2. The cable to power the motor is too long
3.Inverter overheating
4. Déconnection of a wiring on the power
terminal of the inverter
1. Eliminate peripheral faults
2. Additionally install the reactor or
the output filter
3. Check the air duct is blocked or not
and the fan is working normally or not,
and eliminate problems
4. Corectly plug all cables
Err.02
Overintensity
during the
acceleration
1. Acceleration time is too short
2. Increase of the torque or the V/F curve is
not well adaptated
3.the voltage is weak
4.Short circuit or output grounding
5. The motor is started in an unexpected way
6. Sudden increase of the load during the
acceleration
7. The inverter model is to weak for the motor
power
1. increase acceleration time
2. Adjust manual torque boost or V/F
curve
3. Set the voltage to the normal range
4. Eliminate periphereal defects
5. Perform indication for the motor
parameters
6. Select speed tracking start or restart
after stopping the motor
7. Cancel the sudden load
Err.03
Overintensity
during the
deceleration
1. Short circuit or output grounding
2. Deceleration time is too short
3. The voltage is weak
4. Sudden increase of the load during the
deceleration
5. No presence of braking unit and braking
resistors
1. Check and verify the wiring
2. Increase deceleration time
3. Set output voltage equal to the motor
voltage
4. Eliminate the sudden load
5. Install a braking unit and braking
resistors
Err.04
Overintensity in
steady speed
1. Court-circuit or output grounding
2. The voltage is weak
3. Sudden increase of the load
4. The inverter model is too weak for the
motor power
1. Eliminate periphereal defects
2. Set output voltage equal to the motor
voltage
3. Eliminate the sudden load
4.Chose an inverter model more
powerful
Err.05
High voltage
during the
acceleration
1. No presence of braking unit and braking
resistors
2. Input tension is to high
3. An external force prevents the motor
rotation during the acceleration time
4. Acceleration time is too short
1. Install a braking unit and braking
resistors
2. Set the input voltage to the great
value
3. Eliminate the force which prevents
the motor rotation
4.Increase acceleration time
