Fanuc alarm SV0369: DATA TRANS. ERROR (INT)
αi/βi Servo (SV0xxx) · Fanuc 0i-D
What it means
Communications data received from the built-in pulse coder contained CRC errors or stop-bit errors. Unlike SV0368 (no data received at all), packets are arriving but corrupted in transit, which shifts suspicion toward the cable run and connectors as well as the encoder transmit stage. Inspect the cable for pinch points and re-seat connectors at both ends before condemning the coder.
Likely causes
- Damaged/pinched feedback cable causing bit corruption
- Loose or oxidized connector contacts
- Encoder transmit circuitry degradation
- Noise coupling from high-current cabling
