SIC-LSI Faulty (Spindle Amplifier Side, 30i Range)

Was bedeutet SP1980 ?

The SIC-LSI (Serial Interface Converter-LSI) on the serial spindle amplifier side for Series 30i (codes SP1980 to SP1984) is faulty. This indicates a hardware error on the amplifier's communication interface.

• Faulty Serial Interface Converter-LSI on the spindle amplifier (30i range).
• Power delivery issues to the amplifier's communication interface.
• Interference on the communication lines affecting SIC-LSI operation.
• Defective integrated circuit on the amplifier's main board.
• Incorrect firmware version installed on the amplifier.

1. 1

   Measure the DC voltage rail supplying the SIC-LSI component.

2. 2

   Verify ground connections for the amplifier's communication interface.

3. 3

   Visually inspect the SIC-LSI and surrounding components for thermal stress.

4. 4

   Attempt a firmware update for the spindle amplifier if available.

5. 5

   Confirm that the amplifier is receiving the correct nominal input voltage (e.g., 200-240VAC).
