Lenze · 9300 Series
¿Qué significa 075 ?
An error exists in the parameter set, often triggered after an operating system software update. The device automatically loads the Lenze default settings.
Causas comunes
- 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.
Pasos de reparación & Lista de verificación
Haga clic en los pasos para seguir su progreso.
- 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
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
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
Verify the stability of the control voltage supply (e.g., 24VDC) during device startup and parameter write operations to prevent write errors.
