Diff. in hardw. detection

What does F01612 mean?

The drive's internal hardware (safety or non-safety related) could not be correctly identified during startup or runtime. This indicates a mismatch between the expected and detected hardware configuration or a fundamental issue with processor communication, preventing the drive from operating safely.

• Incorrectly inserted or faulty optional modules (e.g., communication board, sensor module, Terminal Module) in the drive's slots.
• Control unit (e.g., CU250S-2, CU320-2) hardware version mismatch with the loaded configuration or the expected firmware version.
• Corrupted internal configuration data preventing proper hardware identification during startup.
• Loose internal connections or damaged components on the main control unit board causing faulty detection.
• Attempting to restore a parameter set from a different hardware variant or type of drive that is incompatible with the installed unit.

Click steps to track your progress.

1. 1

   1. Power cycle the drive and check if the fault clears, as it might be a temporary detection issue.

2. 2

   2. Power down the drive, then verify that all optional modules (e.g., TM modules, CBE cards) are correctly seated in their slots and are compatible with the drive model.

3. 3

   3. Check the firmware version of the control unit and ensure it is compatible with all installed hardware components and the project configuration.

4. 4

   4. Back up the drive parameters, perform a factory reset (P0010=30, P0970=1), and then reload a known good parameter set created for this specific hardware configuration.

5. 5

   5. Review parameter r0947 (Fault history) for additional details or sub-faults that might specify which hardware component is causing the identification issue.

6. 6

   6. If possible, test by temporarily removing non-essential optional modules one by one to isolate the faulty or incompatible component.

7. 7

   7. Replace the control unit (e.g., CU320-2 PN) if the fault persists and no specific module is identified as faulty, indicating an internal hardware defect.
