Fanuc · Alpha i Series Servo Amplifier
What does SV0364 mean?
The digital servo software detected an abnormality on the built-in Pulsecoder related to its phase. This is a software-detected issue with the Pulsecoder's feedback.
Common Causes
- Software error in the digital servo processing phase data.
- Incorrect interpretation of Pulsecoder phase signals by the CNC.
- Firmware bug in the servo controller related to Pulsecoder processing.
- Timing mismatch between Pulsecoder and servo system.
