Yaskawa Error Code Reference — All 166 Codes

Complete Yaskawa error code cheat sheet. All 166 fault codes with plain-English explanations and direct links to fix guides.

Use this page when your Yaskawa 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.

Tip: search the exact brand, model, and alarm together, for example "Yaskawa F0001" or "Yaskawa overcurrent fault".
