ABB Drive Troubleshooting: How to Decode Fault Codes and Get Back Online Fast

When an ABB variable frequency drive (VFD) trips or faults out, your productivity takes a hit. Whether it powers a motor on a production line, pump station, or HVAC system, every second offline can cost time and money. At Delta Automation, we know how critical uptime is—that’s why we’re here to help you quickly interpret ABB fault codes and get your systems back online.
This guide covers the most common ABB drive fault codes, what they mean, and what steps to take next.
Why ABB Drives Trip or Fault
ABB drives are designed with robust diagnostics that protect motors, applications, and the drives themselves. Faults are triggered by abnormal conditions such as:
- Overcurrent or overvoltage
- Ground faults
- Motor wiring errors
- Excessive temperature
- Communication failures
- Configuration or parameter mismatches
Understanding these messages helps you avoid unnecessary downtime and costly service calls.
How to View Fault Codes on ABB Drives
Most ABB drives display fault information directly on their keypad or HMI. For example:
- ACS355 and ACS310: Show fault codes with descriptions on the screen
- ACS580 and ACS880: Offer advanced diagnostics via keypad or ABB’s Drive Composer software
Use the fault code, event history, and timestamps to pinpoint what triggered the issue and when.
Common ABB Drive Fault Codes and Solutions
⚠️ F0001 – Overcurrent
Cause: Sudden load increase, short circuit, or rapid acceleration
Solution:
- Check motor and load for mechanical binding
- Verify acceleration time isn't too short
- Inspect output wiring for faults
⚠️ F0002 – Overvoltage
Cause: Excessive input voltage or deceleration without braking
Solution:
- Add or inspect dynamic braking resistors
- Extend deceleration time
- Check incoming power supply
⚠️ F0003 – Undervoltage
Cause: Input power dips or missing phase
Solution:
- Confirm consistent 3-phase input power
- Check for loose wiring or blown fuses
⚠️ F0005 – Device Overtemperature
Cause: High ambient temperature, blocked airflow, or dirty cooling system
Solution:
- Clean vents and fans
- Ensure drive is installed with proper ventilation
- Consider using external cooling
⚠️ F0010 – Motor Stalled
Cause: Load is too heavy, or motor can’t reach speed
Solution:
- Check for mechanical jamming
- Review torque settings and motor sizing
- Test motor windings for damage
⚠️ F0022 – Earth Fault
Cause: Ground fault in motor or output cables
Solution:
- Use insulation tester (megohmmeter) to check for ground faults
- Inspect cable insulation and terminal connections
⚠️ F0023 – Internal Fault
Cause: Control board or firmware issue
Solution:
- Power cycle the drive
- If persistent, contact a service technician or arrange a replacement
Tips to Prevent ABB Drive Faults
Proactive maintenance goes a long way. Here are a few best practices:
- Keep drives clean and dust-free
- Monitor ambient temperature and humidity
- Regularly back up parameters and firmware
- Use shielded cables and proper grounding to avoid EMI issues
- Ensure correct drive sizing during initial selection
