Expected fault during component replacement

What does F01680 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.

• A Control Unit (CU) or Power Module (PM) has been replaced, and the system is detecting hardware differences during initial power-up.
• Firmware version mismatch between a newly installed component and existing system components, causing an initialization error.
• Parameter inconsistencies or missing data after a component replacement, especially if parameters were not backed up and restored.
• Incorrect installation or seating of a newly replaced module (e.g., loose connections on the Control Unit).

Click steps to track your progress.

1. 1

   1. Confirm that the component replacement (e.g., Control Unit, Power Module) was completed successfully and all connections are secure.

2. 2

   2. Perform a parameter reset to factory defaults (e.g., p0010 = 30, p0970 = 1) if parameter backup/restore was not performed prior to replacement.

3. 3

   3. Download the correct parameter set from a backup (if available) to the newly installed component using commissioning software (e.g., STARTER, TIA Portal).

4. 4

   4. Execute a firmware update on the replaced component to match the system's current firmware version, if necessary.

5. 5

   5. Cycle power to the drive system after ensuring all modules are correctly installed and parameters are loaded.
