ASIC Version Fault

What does CPF10 mean?

Control circuit damage, specifically an ASIC version fault. This indicates an incompatibility or corruption within the ASIC firmware or hardware itself, preventing proper drive functionality.

• Mismatch between the firmware version loaded on the main CPU and the expected version of the ASIC, indicating an incompatibility.
• Corruption of the ASIC's internal firmware or configuration data, preventing it from reporting its version correctly.
• Physical damage or manufacturing defect to the ASIC chip itself, leading to incorrect version identification.
• Failed firmware update attempt that left the ASIC in an inconsistent state.
• Intermittent communication failure between the CPU and ASIC during version negotiation.

Click steps to track your progress.

1. 1

   Power cycle the drive, ensuring a prolonged power-off period (e.g., 60 seconds) to allow all internal components to fully reset.

2. 2

   Verify the drive's main firmware version (e.g., displayed on initial power-up or via a specific parameter) is compatible with the installed hardware.

3. 3

   Attempt to clear all drive parameters to factory defaults (e.g., Parameter A1-03=20) to reset any corrupted configuration data.

4. 4

   Inspect the drive's main control board for any visible physical damage, particularly around the ASIC chip.

5. 5

   Check for stable internal regulated power supplies (e.g., 3.3V, 5V) at accessible test points on the control board.
