3130 Input Phase Loss Fault in ABB ACS580 Drive

3130 Input Phase Loss Fault in the ABB ACS580 Drive indicates that the drive has detected oscillation in the intermediate DC bus voltage caused by a missing input phase or a blown input fuse. When one of the three input phases is lost or becomes unstable, the DC bus voltage develops excessive ripple, causing the drive to trip with Fault 3130 to protect the power electronics.

3130 Input Phase Loss Fault in ABB ACS580 Drive


This fault generally indicates a problem with the incoming power supply, rather than the motor or the drive output stage.

Possible Causes

  • Missing input power phase.
  • Blown input power fuse.
  • Loose input power cable connection.
  • Unbalanced three-phase power supply.
  • Poor electrical connection at the supply terminals.
  • Damaged input cable.
  • Faulty upstream circuit breaker or contactor.
  • Excessive voltage imbalance between phases.
  • Power distribution system fault.

Solutions

  1. Check the input power line fuses.
    • Replace any blown fuse with the correct type and rating.
  2. Check for loose power cable connections.
    • Tighten and secure all incoming power terminals.
  3. Check for input power supply imbalance.
    • Measure the three-phase supply voltage and correct any imbalance.

Additional Information

The ABB ACS580 continuously monitors the DC bus voltage. If one of the input phases is lost, the DC bus voltage develops excessive ripple that exceeds the allowable limit, resulting in Fault 3130 Input Phase Loss.

According to ABB, the recommended corrective actions are to:

  • Check the input power line fuses.
  • Inspect for loose power cable connections.
  • Verify that the input power supply is balanced.

Unlike an Output Phase Loss fault, 3130 is caused by a problem on the incoming AC power supply feeding the drive.

Common Symptoms

  • Drive displays 3130 Input Phase Loss Fault.
  • Drive trips immediately after startup or during operation.
  • Motor stops unexpectedly.
  • Reduced motor torque before the trip.
  • DC bus voltage ripple increases.
  • One input fuse may be blown.
  • Input voltage measurements show a missing or low phase.
  • Drive cannot restart until the supply fault is corrected.
  • Repeated trips if the power supply remains unstable.
  • Possible flickering or unstable operation before the fault occurs.

Recommended Troubleshooting Sequence

  1. Verify that the fault is 3130 Input Phase Loss Fault.
  2. Disconnect power and follow lockout/tagout procedures.
  3. Inspect all input power fuses.
  4. Measure the three-phase input voltage.
  5. Verify that all three phases are present and balanced.
  6. Check the incoming power cable connections and terminal tightness.
  7. Inspect upstream breakers, contactors, and disconnect switches.
  8. Correct any supply imbalance or replace faulty components.
  9. Restore power and reset the fault.
  10. Confirm stable operation under normal load.

Preventive Maintenance Tips

  • Periodically inspect and tighten input power terminals.
  • Check input fuses during routine maintenance.
  • Monitor the incoming three-phase voltage for imbalance.
  • Keep electrical panels clean and free from moisture.
  • Inspect power cables for signs of overheating or damage.
  • Ensure upstream protective devices are correctly rated.
  • Record recurring 3130 Input Phase Loss faults to identify power quality issues.
  • Perform regular preventive maintenance on the facility power distribution system.
  • Use a stable, balanced three-phase power supply.
  • Follow ABB preventive maintenance recommendations for the ACS580 drive.

Proper inspection of the input power line fuses, power cable connections, and three-phase supply voltage will help prevent recurring 3130 Input Phase Loss Fault conditions in ABB ACS580 drives, ensuring reliable power delivery, stable DC bus voltage, and long-term drive performance.
