SP0140

Count Error Alarm

Fanuc · Alpha i Series AC Servo Motor and Spindle

¿Qué significa SP0140 ?

The number of pulses between one phase Z and another (e.g., phase A/B) is shifted by 4λ or more. This indicates a significant discrepancy in the encoder feedback signals, affecting accurate position tracking.

Causas comunes

  • Accumulated count value from a sensor or counter has exceeded its maximum limit.
  • Hardware or software error in the counting mechanism.
  • External reset or interference causing the count to be lost or corrupted.
  • Incorrect configuration of counter parameters or scaling.
  • Rapid pulses or events overwhelming the counting capacity.

  1. 1

    Check the wiring and shielding of the pulsecoder feedback cables (e.g., K16/K97) for loose connections or damage.

  2. 2

    Verify the correct phasing and amplitude of the A, B, and Z signals from the pulsecoder using an oscilloscope.

  3. 3

    Inspect the pulsecoder for any physical damage or contamination on the sensor ring that could disrupt pulse counting.
