Excessive Velocity Error

¿Qué significa SP0002 ?

The spindle motor's actual velocity deviated excessively from the commanded velocity. This can be caused by mechanical load, incorrect tuning, or encoder issues.

• Insufficient torque from the spindle amplifier to meet commanded speed.
• Mechanical load changes exceeding amplifier capacity.
• Encoder feedback signal noise or loss of signal.
• Tuning parameters for velocity control (e.g., P1-02, P1-03) are suboptimal.
• Spindle encoder resolution mismatch with amplifier settings.

1. 1

   Inspect the encoder feedback cable for damage and ensure secure connections.

2. 2

   Verify that velocity feedback parameters (e.g., P1-02, P1-03) are appropriately tuned.

3. 3

   Measure the output voltage of the spindle amplifier during acceleration.

4. 4

   Check for any mechanical issues on the driven spindle or gearbox.

5. 5

   Confirm the encoder resolution matches the value configured in P1-06.
