SIC-LSI Faulty (Spindle Amplifier Side, 15i)

What does SP0980 mean?

The SIC-LSI (Serial Interface Converter-LSI) on the serial spindle amplifier side for Series 15i is faulty. This indicates a hardware error on the amplifier's communication interface.

• Failure of the Serial Interface Converter-LSI chip on the spindle amplifier.
• Internal short circuit within the spindle amplifier's communication circuitry.
• Power supply fluctuations affecting the SIC-LSI operation (e.g., below 5V).
• Overheating of the spindle amplifier causing SIC-LSI malfunction.
• Corrupted firmware within the spindle amplifier's control board.

Click steps to track your progress.

1. 1

   Measure the regulated 5V supply to the SIC-LSI chip on the amplifier board.

2. 2

   Inspect the SIC-LSI chip for visible signs of damage or overheating.

3. 3

   Attempt to clear amplifier alarms via the CNC interface (e.g., 'Reset' button).

4. 4

   Check for diagnostic indicators or LEDs on the amplifier's main board.

5. 5

   Verify the spindle amplifier's operating temperature is within specification.
