Abnormality in spindle amplifier ID data is detected. Replace the Spindle Amplifier.
Steps to Troubleshoot and Confirm the Cause
- Reboot the CNC: Power down the CNC completely, wait a few minutes, and power it back up. Sometimes, temporary system glitches cause ID reading errors that a restart can clear.
- Inspect and Secure Connections: The communication between the CNC controller and the spindle amplifier relies on stable connections. Check all cables and connections related to the spindle amplifier to ensure they are properly seated and free of dust or corrosion.
- Verify Power Supply and Environmental Conditions: Ensure the spindle amplifier is receiving a stable power supply and that the CNC’s environment is free from excess dust, heat, or humidity, which could interfere with normal operations.
- Check for Software or Parameter Errors: In rare cases, ID data errors could be related to software or parameter issues within the controller. Ensure your machine’s software is up to date and that all parameters related to the spindle amplifier are correct.
- Replace the Spindle Amplifier: If all connections are secure and the issue persists, the spindle amplifier may have an internal fault, such as damaged circuitry or memory, which necessitates replacement to restore function.
- Consult Fanuc or CNC Technician: If you’re uncertain about the error or if replacing the amplifier is challenging, consult with Fanuc technical support or a certified CNC technician.

Troubleshooting Steps:
- Power Cycle and Reset: Turn off the machine, wait for a few minutes, and restart it to see if the error persists. This can sometimes clear temporary errors in the control circuit.
- Inspect Connections: Check that all cables and connectors associated with the Spindle Amplifier PCB are secure, as loose connections can cause memory errors.
- Check Environmental Factors: Excessive heat, dust, or moisture can affect sensitive control components. Ensure the machine environment is clean and within operating temperature.
- Replace the Spindle Amplifier Control PCB: If the error persists, it may indicate a hardware fault in the control circuit’s PCB, and replacing it is likely necessary to restore normal operation.
- Consult Documentation or Contact Fanuc Support: Specific troubleshooting for RAM abnormalities may be covered in Fanuc’s technical documentation, and support may provide model-specific guidance for replacing the PCB safely.

Based on the information provided, here are descriptions for each step and related question concerning the Fanuc SP9015 SPINDLE SWITCHING FAULT:
This step involves examining the CNC machine’s ladder logic to ensure that the sequence of operations is correctly programmed. An incorrect ladder sequence may lead to improper spindle switching and trigger the SP9015 fault.
The switching magnetic contactor (MC) may be faulty if it fails to engage or disengage properly. Replacing a defective MC can resolve issues where the mechanical switching is not occurring as expected, leading to the SP9015 fault.
An abnormal switch sequence during spindle or output switch operations indicates a potential issue in the control logic or hardware. Verifying and correcting this sequence is crucial to ensure proper machine operation and avoid the SP9015 fault.
If the status check signal of the switching MC does not align with the command being given, it suggests a discrepancy that can cause the machine to detect an error. This mismatch needs to be resolved to clear the SP9015 fault.
Each of these descriptions and questions addresses specific troubleshooting actions or considerations for resolving the SP9015 fault in Fanuc CNC systems.
