Receive Error (CNC-Spindle, 30i)

What does SP1227 mean?

A receive error occurred in communication between the CNC and the serial spindle amplifier for Series 30i. This indicates an issue with the data reception at the CNC or potentially corrupted incoming data.

• The spindle amplifier failed to correctly receive data from the CNC (30i).
• Corrupted data packets on the serial line.
• Intermittent connection issues on the serial communication path.
• A buffer overflow in the spindle amplifier's receive buffer.

Click steps to track your progress.

1. 1

   Inspect the spindle amplifier's status register for specific receive error codes.

2. 2

   Verify the serial cable is securely connected at both the CNC and amplifier ends.

3. 3

   Measure the signal quality on the RXD line during communication.

4. 4

   Try communicating with a different serial device to isolate the issue.
