Professional maintenance of B&R servo drives and power supplies to safeguard your industrial equipment

In the complex system of industrial automation production, B&R servo drives and power supplies play a core role, and their stable operation directly affects the smoothness of the entire production process. However, prolonged high-intensity operation inevitably leads to various malfunctions of the equipment. We provide comprehensive, efficient, and accurate B&R equipment maintenance services with our profound professional skills and rich practical experience, helping enterprises maintain an efficient production pace.

1、 Common faults and professional maintenance of B&R servo drives

B&R servo drives may experience various complex faults during long-term use:
1. Display and output faults: No display problems are usually caused by abnormal power supply, loose connection lines of the display screen, or hardware damage to the display module. The absence of display output faults may be caused by obstructed control signal transmission, abnormal power module operation, or internal circuit short circuits. Our professional maintenance team can quickly locate the fault point, restore the normal display and output function of the equipment through fine inspection and precise repair.
2. Electrical performance failure:
*Overcurrent: It may be caused by excessive motor load, short circuit of motor winding, aging of driver power module, or malfunction of current detection circuit. Once overcurrent occurs, the drive will automatically trigger a protection mechanism, causing the device to shut down. Our technicians, with professional testing equipment, can accurately identify the root cause of overcurrent and take targeted measures, such as replacing damaged power modules, repairing short circuited motor windings, etc., to ensure that the equipment resumes normal operation.
*Overvoltage and undervoltage: Overvoltage faults are generally caused by excessive fluctuations in the input voltage of the power supply, failure of the internal voltage regulation circuit of the driver, or ineffective consumption of regenerative braking energy of the motor. Undervoltage faults are often caused by poor contact of the power input line, damage to the voltage conversion module, or unstable grid voltage. We ensure that the driver can operate stably in various voltage environments through comprehensive testing and optimization of the power circuit.
*Phase loss: The main reasons include unbalanced three-phase voltage on the power input side, poor contact of contactors or relays, and damage to one phase of the internal three-phase rectifier bridge or inverter bridge of the driver. Phase loss not only affects the normal operation of equipment, but may also cause irreversible damage to the motor. We can quickly identify the cause of phase loss, repair damaged components, and ensure stable supply of three-phase power.
3. Overheating and overload:
Overheating faults are usually caused by damage to the driver's cooling fan, excessive dust accumulation on the cooling fins, high working environment temperature, or prolonged high load operation of internal power components. Overload faults are often caused by the load carried by the motor exceeding its rated range, or improper settings of the driver parameters, resulting in the driver continuously outputting excessive current. We effectively solve overheating and overload problems and extend the service life of equipment by cleaning and maintaining the cooling system, load detection, and parameter optimization.
4. Grounding and parameter errors:
Grounding faults are mostly caused by damage to the insulation layer of the internal circuit of the motor or driver, resulting in current leakage to the grounding terminal. Parameter errors may be caused by abnormal power outages, human error, or software failures, resulting in loss or disorder of internal parameters in the drive. Our technical team is able to accurately repair grounding faults, recalibrate parameters, and ensure stable equipment operation.
5. Module damage:
The modules of B&R servo drives, such as power modules, control modules, etc., are prone to damage due to prolonged exposure to high voltage, high current, and complex working environments. We have advanced testing equipment and rich maintenance experience, which can accurately identify damaged modules and replace them with high-quality original parts to ensure that the equipment performance is restored to its original state. We specialize in repairing various models of B&R servo drives, including ACOPOS1045, ACOPOS1320, ACOPOS128M, ACOPOS1180, ACOPOS1010, etc. Every repair strictly follows the standardized process, from fault diagnosis, parts replacement to performance testing after repair, every link is carefully controlled to ensure that the repaired equipment fully meets or even exceeds the original factory standards.
