The following are common ABB inverter fault codes and their interpretations:
0001: Overcurrent
Reason: The output current exceeds the trip value.
Possible measures: Check the motor load to ensure it does not exceed the rated load of the frequency converter;
Checking the acceleration time and extending it appropriately may help reduce overcurrent;
Check the motor and motor cables to ensure that they are not short circuited or damaged;
Check the surrounding environmental conditions, such as whether the temperature in the computer room is too high.
0002: Overvoltage
Reason: The intermediate current and DC voltage are too high. The tripping value of the DC voltage in the intermediate circuit of a 200V frequency converter is 420V,
and the tripping value of the DC voltage in the intermediate circuit of a 400V frequency converter is 840V.
Possible measures: Check the overvoltage controller;
Check the steady-state and transient voltages of the input power supply to ensure they are within the normal range;
Check the brake chopper and brake resistor to ensure they are working properly;
Checking the deceleration time and extending it appropriately may help reduce overpressure.
0003: Trip (IGBT temperature too high)
Reason: The IGBT temperature of the frequency converter is too high, and the trip value is 135 ° C.
Possible measures: Check the surrounding environmental conditions, such as whether the temperature in the computer room is too high;
Check the cooling air flow and cooling fan;
Check the motor power and load to ensure they are not overloaded.
0004: Short circuit
Reason: Motor cable or motor short circuit.
Possible measures: Check the motor and motor cables to ensure they are not short circuited or damaged.
0006: Low voltage
Reason: Due to power phase loss, burnt fuses, internal faults in rectifier bridges, or low power supply voltage, the DC voltage in the intermediate circuit is too low. The DC undervoltage trip value of the intermediate circuit of the 200V frequency converter is 162V, and the DC undervoltage trip value of the intermediate circuit of the 400V frequency converter is 308V.
Possible measures: Check the undervoltage controller;
Check the power supply and fuses to ensure they are not faulty or damaged.
0007: Analog input AI1 below parameter limit
Reason: The simulated input AI1 is lower than the limit defined by parameter 3021 AI1 Fault Limit.
Possible measures: Check the parameter settings of the faulty function;
Check if the voltage level of the analog control signal is correct;
Check if the wiring is connected correctly.
0008: Analog input AI2 below parameter limit
Reason: The simulated input AI2 is below the limit defined by parameter 3022 AI2 Fault Limit.
Possible measures: Similar to 0007, check the parameter settings of the fault function, analog control signal voltage level, and wiring connections.
0009: High motor temperature
Reason: Motor overheating may be caused by overload, low motor power, insufficient cooling, or incorrect starting data.
Or the measured temperature of the motor has exceeded the fault limit defined by parameter 3504 Fault Limit.
Possible measures: Check the rated parameters, load, and cooling condition of the motor;
Check if the startup data is correct;
Check if the fault limit and sensor model settings are correct; Let the motor cool down and check if the cooling fan and cooling surface are clean.
0010: Operation panel stops communication
Reason: The control panel selected as the effective control location has terminated communication.
Possible measures: Check if the control panel connection is normal;
Check the parameter settings of the fault function;
Check if the control panel connector is damaged or loose; Replace the control panel on the installation board.
The following points should be noted:
Refer to the manual: Different models of ABB frequency converters may have different fault codes and solutions,
so it is necessary to refer to the corresponding model's user manual or technical documentation for accurate information.
Analyze the cause: based on the fault code and possible reasons, analyze the specific cause and possible impact of the fault occurrence.
Take measures: based on the analysis results, take corresponding measures to solve the problem.
This may include inspecting motors and cables, adjusting parameter settings, replacing damaged components, etc.
Regular maintenance: In order to reduce the failure rate of the frequency converter, regular maintenance and upkeep work should be carried out.
