About ErrorLib

What We Do

Industrial equipment — variable frequency drives, PLCs, servo drives, softstarters — generates fault codes when something goes wrong. Finding the right troubleshooting information often means searching through hundreds of pages of manufacturer documentation.

ErrorLib compiles and indexes fault codes from publicly available manufacturer manuals, making them instantly searchable. Every fault code entry includes a clear description and step-by-step troubleshooting instructions written for field technicians.

Our Coverage

We currently cover major industrial automation brands including ABB, Siemens, Danfoss, Yaskawa, Schneider Electric, Vacon, SEW Eurodrive, Allen-Bradley, and more. Our database is continuously expanding based on user requests and industry demand.
