Expected fault during component replacement

What does F30680 mean?

This fault is part of a group (F01641, F01650, F01680, F30680) that is expected to occur temporarily during specific corrective maintenance procedures, such as replacing a Control Unit or the entire inverter. It does not indicate a persistent problem if the full replacement and recommissioning steps are followed. The risk is negligible if acknowledged as part of the procedure.

• Power unit detected no valid Control Unit firmware or missing licensing information during initial boot sequence.
• Hardware incompatibility between the newly replaced Control Unit and the existing power module (e.g., incorrect hardware revision for integration).
• Loss of internal communication between critical sub-modules (e.g., temperature or current sensors) due to incorrect mounting or misaligned connectors.
• Control unit is inserted but not correctly powered or initialized, preventing it from establishing necessary communication with other modules.

Click steps to track your progress.

1. 1

   1. Confirm that the Control Unit's locking mechanism is fully engaged and that it is seated flush with the power module chassis.

2. 2

   2. Verify the part numbers of the replaced Control Unit and the existing power module against manufacturer compatibility lists and documentation.

3. 3

   3. Perform a full power cycle of the entire drive system, waiting at least 30 seconds after power-off before reapplying power.

4. 4

   4. Check for any visible damage on the backplane connectors of both the Control Unit and the slot it plugs into, ensuring pins are straight and clean.

5. 5

   5. Attempt a system restore or firmware re-flash procedure for the Control Unit if proper seating and compatibility are confirmed, using vendor-specific commissioning tools.
