Fagor alarm 24004: EtherCAT: Working Counter error
CNC 8058/8060/8065/8070 CNCelite EtherCAT error (Quercus drives) · Fagor 8058
What it means
The accumulated working counter returned by the slaves no longer matches the expected value, proving at least one slave processed frames incorrectly or dropped out momentarily. It is a classic early symptom of a failing node ahead of full datalink collapse.
Likely causes
- one EtherCAT slave (drive/RIO) operating erratically
- borderline signal quality from long or damaged cabling
- node firmware crash requiring power cycle
