Count Error Alarm

What does SP0140 mean?

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.

• 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.

Click steps to track your progress.

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.
