Fagor alarm 8820: Message out of range
CNC 8060/8065/8070 CNC error · Fagor 8060/8065/8070
What it means
While editing the PLC program a message resource was referenced outside MSG1-MSG1024. Messages (MSG) carry OEM-defined warning/screen texts; the same numbered resource is what #MSG-style interfaces display. Renumber within range or enlarge usage planning for message texts.
Likely causes
- MSG index typo (>1024 or 0)
- porting PLC code from families with different message counts
- auto-generated code overflowing message numbering scheme
