Framing Error (CNC-Spindle, 30i)

What does SP1226 mean?

A framing error occurred in communication between the CNC and the serial spindle amplifier for Series 30i. This typically indicates a mismatch in communication protocol or timing parameters.

• Data framing error in serial communication between CNC and spindle amplifier (30i).
• Incorrect start or stop bits configuration in serial communication settings.
• Data bits misalignment due to incorrect baud rate or bit timing.
• A faulty UART on either the CNC or the spindle amplifier.

Click steps to track your progress.

1. 1

   Verify serial communication parameters (baud rate, data bits, stop bits, parity) match on both ends.

2. 2

   Inspect the serial data signal integrity at the terminal block.

3. 3

   Ensure the serial connector is clean and properly seated.

4. 4

   Test the serial port functionality by using a loopback connector.
