An error exists in the parameter set, often triggered after an operating system software update. The device automatically loads the Lenze default settings.

• Incomplete/corrupt firmware update: The operating system (OS) software update process was interrupted or failed, resulting in an inconsistent firmware version or corrupted parameter storage structure.
• Parameter incompatibility: The new OS firmware version has a different parameter structure or range, making the previously saved parameter set incompatible.
• Power fluctuation during update: Unstable power supply occurred during the critical phase of writing the new OS firmware or parameters, leading to data corruption.
• Internal memory wear/fault: The non-volatile memory (e.g., EEPROM, Flash) storing the parameters has reached its write endurance limit or has a physical defect.

1. 1

   Confirm that the operating system software update completed successfully and that the new firmware version is correctly reported (e.g., parameter P0-01).

2. 2

   Reload the parameter set (e.g., using a backup via keypad or communication software) after the device has automatically loaded default settings, ensuring it's compatible with the new OS.

3. 3

   If the error persists after reloading a known-good, compatible parameter set, perform a full factory reset (e.g., P0-10 = 110) and then re-enter essential parameters manually.

4. 4

   Verify the stability of the control voltage supply (e.g., 24VDC) during device startup and parameter write operations to prevent write errors.
