SP0982
SIC-LSI Read Error (Spindle Amplifier Side, 15i)
Fanuc · AC Spindle Motor Alpha i-Beta i Series Parameters
What does SP0982 mean?
An error occurred when data was read from the SIC-LSI on the serial spindle amplifier side for Series 15i. This indicates a data integrity or hardware reading issue within the amplifier's communication interface.
Common Causes
- Read circuitry malfunction on the SIC-LSI within the spindle amplifier.
- Data corruption during read operations from the SIC-LSI.
- Incorrect command sequence for reading from the SIC-LSI.
- Hardware fault on the amplifier's main board preventing data retrieval.
- SIC-LSI memory cell failure.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Attempt to read data from multiple SIC-LSI registers to identify a pattern of failure.
- 2
Verify the read command timing against the amplifier's specifications.
- 3
Measure the voltage levels on the serial data lines during a read attempt.
- 4
Perform a diagnostic routine for the SIC-LSI if available in the amplifier's menu.
- 5
Ensure the CNC is correctly interpreting the data received from the amplifier.
