What are the Common faults on the ACS580 and how do I fix them?

As a highly popular drive, the ABB ACS580 can be found in many industrial settings, but what are its most common faults and more importantly how can you fix them to avoid downtime?  We discuss the most common issues and how to fix them below;

  • Overcurrent Faults: This can occur due to excessive load or a short circuit.  Check the load conditions, ensure proper cooling, and inspect the motor and cables for any faults.
  • Overvoltage/Under voltage Faults: Verify the input voltage levels and ensure they are within the specified range.  If necessary, use a line reactor or check the power supply for stability.
  • Overtemperature Faults: Overheating can result from inadequate ventilation or excessive load. Ensure proper cooling, ventilation and check the ambient temperature around the drive.
  • Ground Faults: Check the motor and cable insulation for any faults.  Ensure proper grounding and insulation integrity.
  • Communication Faults: If communication with external devices is lost, check the communication cables, settings, and connections.


To decrease the chances of your drive failing, we highly suggest you conduct preventative maintenance on all VSDs, this includes:

  • Regular Inspections: Periodically inspect the drive for physical damage, loose connections, and signs of overheating.
  • Carry out Recommended Maintenance: All manufacturers will recommend certain components of your drive are replaced at specific intervals to prevent your drive breaking down.
  • Check Ventilation: Ensure proper ventilation for the drive to prevent overheating. Clean any dust or debris that may accumulate on the heat sinks.
  • Verify Calibration: Periodically check and recalibrate the drive parameters to ensure accurate control and performance.
  • Monitor Motor and Drive Conditions: Use diagnostic tools provided by ABB or external monitoring systems to keep track of motor and drive conditions. This helps in identifying potential issues before they escalate.
  • Update Firmware: Stay informed about firmware updates from ABB and consider updating the drive’s firmware to benefit from improvements and bug fixes.


Always refer to the specific user manual and documentation provided by ABB for detailed information on troubleshooting and maintenance procedures for the ACS 580 drive.
