Fagor alarm 5001: PLC error: The counter does not exist
CNC 8060/8065/8070 CNC error · Fagor 8060/8065/8070
What it means
Same class of fault as 5000 but for counters: a read request targeted a counter index outside the valid C1-C256 range. The CNC blocks the access and flags the PLC program. Review counter numbering in the project and recompile.
Likely causes
- counter index out of range in PEP instructions
- renamed/deleted counter still referenced
- copy-paste between projects with different resource sizing
