FPGA Node Internal Fault

What does LED_STA2_FPGA_FLASH mean?

The STA2 LED for the FPGA node on the KUKA KRC4 Sunrise Cabinet Med Controller is flashing, indicating an internal fault. This fault points to an issue with the Field-Programmable Gate Array (FPGA) which is crucial for high-speed processing and logic within the controller.

• Internal malfunction or corruption within the FPGA node.
• Insufficient or unstable power supply (e.g., related to infeed at X1 or PWR/3.3V LED status).
• Firmware corruption or loading error for the FPGA.

Click steps to track your progress.

1. 1

   Verify the main power infeed at connector X1, ensuring the rated voltage of 27.1 V is present.

2. 2

   Observe the PWR/3.3V LED; if it lights up, but STA2 (FPGA) is flashing, the issue is likely internal to the FPGA.

3. 3

   Perform a system power cycle for the KUKA KRC4 Sunrise Cabinet Med Controller to attempt a reset.

4. 4

   If the fault persists, prepare to exchange the CCU_SR module, which contains the FPGA.
