Drive: Power unit EEPROM without rated data

Hva betyr F07810 ?

No rated data is stored in the power unit's EEPROM, which is essential for the drive to operate correctly. This can indicate a faulty EEPROM, an uninitialized power unit, or a replacement unit that has not been properly configured. Without this data, the drive cannot determine its nominal operating characteristics.

• A replacement power unit was installed without a prior backup and restore of critical drive parameters (e.g., P0810 (Power unit rated power), P0811 (Power unit rated current)).
• Internal EEPROM data corruption or failure within the drive's power unit hardware.
• The drive's power unit (e.g., PM240) was replaced without transferring its data from the original unit's Control Unit.
• A firmware update process was interrupted or failed, leading to incomplete data writing to the EEPROM.

1. 1

   1. Perform a full parameter reset (P0010 = 30, P0970 = 1) followed by re-entering all motor and application parameters.

2. 2

   2. If available, restore parameters from a previously saved backup file (e.g., via STARTER or TIA Portal software).

3. 3

   3. Ensure the Control Unit (e.g., CU240E) is correctly mounted and securely connected to the power module.

4. 4

   4. Attempt a firmware update of the drive, ensuring a stable power supply and proper procedure is followed.

5. 5

   5. If the fault persists after parameter restore and firmware update, replace the drive's power unit (e.g., PM240).
