PR0 (Error in parameter set)

Hva betyr 0075 ?

An error has occurred in the parameter set, possibly due to an operating system software update. The Lenze default settings (C0003 = 1) are automatically loaded as a result of this fault.

• Corruption of the stored parameter set in non-volatile memory (EEPROM) due to power fluctuations.
• Incomplete or interrupted parameter download from a higher-level controller or PC software (e.g., Engineer).
• Incompatibility of a saved parameter set with the current firmware version after an update.
• Attempting to restore a parameter set from a different hardware variant or controller model.
• Internal memory error preventing proper loading or saving of parameters.

1. 1

   Cycle power to the drive and check if the fault clears and the default parameters (C0003 = 1) are active.

2. 2

   Verify the current firmware version (C0004) and ensure any loaded parameter set is compatible with it.

3. 3

   Reload the last known good parameter set from a backup file using the drive's configuration software (e.g., "Lenze Engineer").

4. 4

   Manually re-enter critical application parameters (e.g., motor data, speed limits) and save them to non-volatile memory (e.g., by setting C0003 = 2).

5. 5

   If the fault recurs with new parameters, inspect the drive's internal memory health via diagnostic parameters if available (refer to manual for specific memory status indicators).
