Fault
ID
Failure type
Possible causes
Solutions
9
Err.09
Under voltage
fault
1. The momentary power cut
2. The inverter’s input voltage is not within the
specification
3. The bus voltage is not normal
4. The rectifier bridge and buffer resistance are
abnormal
5. The drive panel is abnormal.
6. The control panel is abnormal
1. Reset fault
2. Adjust the voltage to the normal range
3. Seek for technical support
10
Err.10
Inverter overload
1. The type selection of inverter is small
2. Whether the load is too large or the motor stall
occurs
1. Choose the inverter with large power level
2. Reduce the load and check the motor and its
mechanical conditions
11
Err.11
Motor Overload
1. Power grid voltage is too low
2. Whether the setting motor protection parameters
(F8.03) is appropriate or not
3. Whether the load is too large or the motor stall
occurs
1. Check the power grid voltage
2. Correctly set this parameter.
3. Reduce the load and check the motor and its
mechanical conditions
12
Err.12
Input phase loss
1. The drive panel is abnormal.
2. The lightning protection plate is abnormal
3. The main control panel is abnormal
4. The three-phase input power is not normal
1. Replace the drive, the power board or contactor
2. Seek for technical support
3. Check and eliminate the existing problems in
the peripheral line
13
Err.13
Output phase
loss
1. The lead wires from the inverter to the motor is not
normal
2. The inverter’s three phase output is unbalanced
when the motor is running
3. The drive panel is abnormal.
4. The module is abnormal
1. Eliminate peripheral faults
2. Check the motor’s three-phase winding is normal
or not and eliminate faults
3. Seek for technical support
14
