Communication Data Error (CNC Side, 30i Range)

What does SP1245 mean?

A communication data error was detected on the CNC side for Series 30i (codes SP1245 to SP1247). This indicates data corruption during transfer to the CNC.

• Data corruption during transmission between CNC and spindle amplifier (30i range).
• Timing issues with data packets on the communication bus.
• External electromagnetic interference affecting data integrity.
• Faulty transceiver chip on either the CNC or amplifier communication board.
• Incorrect data framing or synchronization within the communication protocol.

Click steps to track your progress.

1. 1

   Measure the signal integrity of the communication bus using a network analyzer.

2. 2

   Verify that parameter P1-54 (communication settings) is accurately configured.

3. 3

   Temporarily disable other peripherals connected to the same bus to rule out interference.

4. 4

   Check for loose connections or damaged shielding on communication cables.

5. 5

   Initiate a data transfer test and monitor for retransmissions or errors.
