ABB ACS580 Error Code F0004

ABB PLC & VFD Critical Drive

Model: ACS580 | Code: F0004

Applicable Systems
AC500 AC590 ACS580 ACS880

Symptoms

The drive trips immediately. The display shows F0004 indicating an output short circuit. The drive has detected a short circuit condition on the motor output terminals.

Possible Causes

  • Short circuit between motor output phases
  • Short circuit between motor output and ground
  • Motor winding short circuit
  • Drive output stage (IGBT) short circuit

Troubleshooting Steps

  1. Step 1: Disconnect the motor cables from the drive output terminals
    Isolate the drive from the motor for testing
  2. Step 2: Measure resistance between each phase at the drive output
    No short circuit is present at the drive output terminals
  3. Step 3: Measure motor winding resistance and insulation to ground
    Motor is healthy with balanced windings and good insulation
  4. Step 4: If the short is in the drive output stage, the drive needs service
    Drive passes output short test after motor cable disconnection

How to Reset

To reset: 1) Remove the short circuit condition (repair or replace motor cable or motor). 2) Press RESET. 3) If the drive output stage is shorted, the drive must be serviced by ABB. Caution: Never reset a short circuit fault without fixing the root cause.

Frequently Asked Questions

  • Q: How do I find a short circuit in motor cables?

    Disconnect the cable from both the drive and motor. Use a megohmmeter to measure insulation resistance phase-to-phase and phase-to-ground. A healthy cable should show megohm-range resistance.

  • Q: Can the drive output stage be shorted without an external short?

    Yes, IGBT failure can cause an internal output short circuit. If the fault persists with motor cables disconnected, the drive output stage is likely damaged.
