Fanuc · Alpha i Series Servo Amplifier
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.
Click steps to track your progress.
Reduce servo motor velocity and observe fault recurrence.
Secure mounting of the servo motor and encoder to minimize vibration.
Test internal Pulsecoder counting accuracy against a reference.
Ensure clean signal transmission for the internal Pulsecoder.
Verify mechanical coupling integrity between motor and driven load.
