Communication Error (CNC-Spindle Amplifier, 30i)

What does SP1228 mean?

A general communication error occurred between the CNC and the serial spindle amplifier for Series 30i. This is a broad indication of communication failure, requiring further investigation into the communication link.

• A general communication failure between the CNC and the serial spindle amplifier (30i).
• Incorrect serial port configuration on either device.
• The spindle amplifier is not powered on or is in a fault state.
• A break in the serial communication line.

Click steps to track your progress.

1. 1

   Verify the serial port configuration parameters in the CNC (e.g., P71-01).

2. 2

   Ensure the spindle amplifier has a stable power supply and no active fault indicators.

3. 3

   Check for continuity on the serial communication wires.

4. 4

   Try a different serial communication protocol if supported.
