I operate a CNC cutting machine with Fanuc components including the CNC CPU A02B-0307-B822, a PLC AIF01A, and an operator panel. Recently, I encountered an alarm error "SV5136: Number of amplifiers not enough" on the operator panel. Upon checking the operational amplifiers, all the status LEDs showed a dash symbol, indicating no issues. Furthermore, both the CNC and operator panel displayed errors, with the PLC showing no active outputs, suggesting a lack of communication. After inspecting the fiber optic cable connecting the CNC with the amplifiers, everything appears to be connected properly. I am seeking suggestions to diagnose and resolve this issue.
If you suspect that your servo parameters have been altered or your FSSB connection is faulty, seeking assistance from CNC experts at cnczone.com may be beneficial. It's important to note that this issue is specific to CNC machinery and not related to your PLC. FSSB is responsible for communication with the servos, not the PLC. If you are experiencing issues with your servos, it's best to consult with CNC professionals for guidance.
From your description, it seems like this could be a breakdown in the communication between your CNC and the amplifier. While you've mentioned that the fiber optic cable isn't showing any apparent physical signs of damage, it might still be worth replacing or testing with an alternate cable if you have one available - sometimes the damage isn't visible to the naked eye. If that doesn't resolve the issue, it could potentially be a software fault. Try updating or reinstalling the CNC software, firmware, or driver associated with the amplifiers. Lastly, I'd suggest contacting Fanuc's support team - they're usually super helpful with this kind of stuff and might be able to diagnose the issue with more specific details.
This sounds like a somewhat tricky issue. However, since you've already checked the hardware and everything seems fine, the problem might be related to a software or configuration setting. I once faced a similar issue and resolved it by rechecking the parameters on the CNC control and the PLC. There might be a mismatch or missetting that’s causing this alarm error. If you've recently updated any software on your components, that could also be the cause. Make sure the recent updates are compatible with your Fanuc components. If your configuration files are okay and there's no software conflict, you may need to consult a Fanuc technician.
It sounds like you're facing a tough situation there! Since the LEDs on the amplifiers are showing a dash, double-checking the communication between your CNC and the PLC could be key. Sometimes, the issue might be with the initialization or configuration settings in the software, especially if the system has recently undergone any updates or changes. Have you tried resetting the CNC and the PLC or checking for any loose connections on the fiber optic cables again? It might also be worth looking into the parameters related to your amplifier setups in the Fanuc manuals, just to confirm everything aligns with the required configuration. Good luck, and I hope you get it sorted out soon!

Answer: Answer: The alarm error SV5136 on a Fanuc CNC system indicates that the number of operational amplifiers required for the system's operation is not sufficient.
Answer: Answer: The dash symbol on the status LEDs of the operational amplifiers typically indicates that there are no issues with the amplifiers themselves.
Answer: Answer: To address the communication issues between components in a Fanuc CNC system causing the SV5136 error, you may need to inspect the connections, check for faulty cables, and verify proper settings for communication protocols.
