Serial Spindle Amplifier Communication Timeout (15i)

¿Qué significa SP0978 ?

A time-out was detected in communication with a serial spindle amplifier for Series 15i. This indicates a delay or failure in receiving a response from the amplifier within the expected timeframe.

• Loss of serial communication with the spindle amplifier.
• High network traffic interfering with timely data packets.
• Excessive processing load on the CNC preventing timely responses.
• Incorrect serial communication parameters set in P1-54.
• Physical damage to the serial communication cable or connectors.

1. 1

   Verify the presence of data activity on the serial communication bus using an oscilloscope.

2. 2

   Set parameter P1-54 to the correct baud rate and protocol settings for the amplifier.

3. 3

   Power cycle the spindle amplifier and the CNC.

4. 4

   Inspect the serial cable for physical damage and ensure secure connections at both ends.

5. 5

   Measure the voltage at the serial communication terminals (e.g., T+, T-, R+, R-) on the CNC side.
