SV0367
COUNT MISS(INT)
Fanuc · Alpha i Series Servo Amplifier
What does SV0367 mean?
A count error occurred on the built-in Pulsecoder, meaning pulses were missed during counting. This directly affects the accuracy of position tracking by the internal encoder.
Common Causes
- High speed rotation exceeding the counting capability of the internal Pulsecoder.
- External vibration causing loss of encoder signal lock.
- Internal Pulsecoder logic circuit malfunction.
- Data transmission errors corrupting pulse counts.
- Incorrect gear ratio or belt tension affecting perceived speed.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Reduce servo motor velocity and observe fault recurrence.
- 2
Secure mounting of the servo motor and encoder to minimize vibration.
- 3
Test internal Pulsecoder counting accuracy against a reference.
- 4
Ensure clean signal transmission for the internal Pulsecoder.
- 5
Verify mechanical coupling integrity between motor and driven load.
