ABB Error Code Reference — All 26 Codes
Complete ABB error code cheat sheet. All 26 fault codes with plain-English explanations and direct links to fix guides.
Use this page when your ABB drive, CNC, servo, or controls hardware posts an alarm during production. Start with the exact code, then open the fix guide for overloads, encoder faults, communication alarms, power quality issues, and drive or board failures.
We don't sell parts, so we'll tell you when not to buy one: 1 of these ABB codes are usually a cheap or free fix, not a failed part. The "Often a cheap fix?" column shows the odds.
Tip: search the exact brand, model, and alarm together, for example "ABB F0001" or "ABB overcurrent fault".
