What do we need to pay attention to when repairing ABB inverters? Nowadays abb inverters are gradually gaining more popularity because of the high quality and durability of the inverter. But the long-term use causes the inverter to generate errors that affect the machine operation and performance.
1.Notes when repairing ABB inverters
If your inverter is faulty, you are looking for inverter repair service, you should note the following:
Find a unit with many years of experience in inverter repair.
Choose services with a highly qualified technical team to ensure quick and professional repairs.
Refer to 3 or more services to choose a place for a reasonable repair cost.
Must ensure replacement repair parts are completely new 100%.
Choose repair places that have a post-repair warranty for you.
2.Common errors and how to repair ABB inverters
2.1.Inverter output overcurrent error – F001: Overcurrent
This error is because the output of the current has exceeded the rating to be interrupted. The workaround is as follows:
Need to check the load of the motor.
It is necessary to check the starting time of the engine.
It is necessary to check the motor and the motor cable.
It is necessary to check the ambient conditions again, the load capacity decreases if the ambient measurement system setting exceeds the temperature level of 40.
2.2.DC Overvoltage Error – F002: DC Overvolt
Usually, this error is caused by an inertial load. Some control functions require the installation of a discharge resistor or the selected discharge resistor value is inconsistent with the capacity and value. The method to solve the problem is as follows:
It is necessary to re-check all control functions of the inverter.
It is necessary to check whether the discharge resistance has met the requirements or not.
It is necessary to check the settings of the inverter to match.
2.3.IGBT Overheat Error – F003: DEV Overtemp
This error is caused by the IGBT temperature control exceeding the interrupt limit of 135 degrees. The method to solve the problem is as follows:
It is necessary to check the environmental conditions again.
Need to check the air volume and fan operation.
Need to double check motor voltage against power unit.
2.4.Inverter short circuit error – F004: Short Circuit
This error is caused by a short in the terminal transformer or in the motor. Methods to solve this problem in the following ways:
Need to check motor and cable for short.
Need to check the inverter for short or burnt out.
2.5.Error of insufficient DC voltage – F0006: DC Undervolt and how to repair ABB . inverter
This error is caused by insufficient DC voltage. Methods to solve this problem in the following ways:
Need to check the 3-phase power input.
Check to see if the fuse is blown.
Need to check if the input source is enough.
2.6.Motor overheating error – F0009: Mot Temp
Causes of this error include: the first is that the motor often operates at near-rated current, the second is that the control board of the inverter device may have been faulty during use.
The ABB inverter repair method is as follows:
It is necessary to double check the operating voltage and current of the motor against these actual values so that the correct cause of the fault can be determined.
2.7.Screen error – F0010: Panel loss
The cause of this error is usually in the communication between the display, main, and cpu of the inverter.
2.8.Inverter or motor grounding error – F0016: Earth Fault
This error usually occurs because the isolation resistance of the motor or the inverter is below the allowable level.
The method to solve the problem is as follows:
It is necessary to check the motor isolation resistance and check the motor connection cable and the length of the connection cable.
2.9.Thermal error – F0018: Therm Fail and how to repair ABB inverter
This error is because the thermistor that measures the internal temperature of the inverter may be open or short circuited.
2.10.Inverter current measurement error – F0021: Curr Meas
There are many causes for this error. You should contact your supplier for assistance.
2.11.Input phase loss error – F0022: Supply Phase
The cause of this error could be a blown fuse or a loss of power phase.
2.12.Overspeed error – F0024: Overspeed
Try setting the parameter value again.
Check brake torque.
Check torque control applicability.
Check the resistance and brake again.
2.13.Motor phase loss error – F0034: Motor Phase
There are 2 causes of this motor phase loss error: the motor output wire is short-circuited or the inverter IGBT is damaged due to the output short circuit.
There are ways to work around this situation:
Need to check the wiring of the motor.
It is necessary to check the control circuit of the inverter.
It is necessary to check and replace the damaged IGBT.
2.14.Inverter output error – F0035: Output Wiring and how to repair ABB inverter
This error may be caused by the inverter output cannot be connected to the motor. To disable this error, you need to deactivate the 3023 parameter and change the value to 0.
