CRC Communication Error (CNC-Spindle, 30i)

What does SP1225 mean?

A CRC (Cyclic Redundancy Check) communication error occurred during data exchange between the CNC and the serial spindle amplifier for Series 30i. This indicates data corruption or signal integrity issues in the communication link.

• Data corruption detected via CRC check during serial communication with the spindle (30i).
• A faulty serial cable or connector causing bit errors.
• Electromagnetic interference corrupting the transmitted data.
• A problem within the spindle amplifier's communication interface.

Click steps to track your progress.

1. 1

   Verify the CRC checksum value reported in the error log.

2. 2

   Inspect the serial communication cable between the CNC and the spindle amplifier for damage.

3. 3

   Ensure proper shielding and grounding of the serial communication lines.

4. 4

   Test communication with a different spindle amplifier if available.
