0883

Serial Separate Detector Machine Velocity Feedback Coefficient Exceeded

Fanuc · Alpha i Series Servo Amplifier

What does 0883 mean?

This invalid parameter setting alarm occurs for an axis equipped with a serial type separate detector when the machine velocity feedback coefficient is set to a value exceeding 100. The upper limit for this coefficient on such axes is strictly 100, and exceeding it causes an error.

Common Causes

  • The machine velocity feedback coefficient has exceeded the maximum allowed value.
  • The serial separate detector is reporting an excessively high velocity feedback.
  • Parameter P601.1 (Serial Velocity Feedback Coefficient) is too high.
  • An internal overflow occurred when processing the serial detector's velocity data.

  1. 1

    Correct the machine velocity feedback coefficient so that its value does not exceed 100 for axes with a serial type separate detector.
