Saving The Parameters Permanently; Parameterization Errors - Siemens SINAMICS S120 Operating Instructions Manual

Access level (factory setting: Expert):
The different parameters required for this complex application are filtered so that they can be
displayed as clearly as possible. You select them according to the access level.
An expert level, which must only be used by expert personnel, is required for certain actions.
Note
Copy RAM to ROM
When the operator input inhibit or parameterization inhibit is activated, a "Copy from RAM to
ROM" is automatically executed to back the parameter settings up in non-volatile memory on
the memory card.

Saving the parameters permanently

Description
If parameters are changed using the operator panel (confirm with OK in the Parameter
editor), the new values are initially stored in the volatile memory (RAM) of the converter. An
"S" flashes in the top right of the AOP display until they are saved to a permanent memory.
This indicates that at least 1 parameter has been changed and not yet stored permanently.
Two methods are available for permanently saving parameters that have been changed:
● To store the parameters permanently, choose <MENU> <Parameterization> <OK>
<Permanent parameter transfer>.
● When confirming a parameter setting with OK, press the OK key for > 1 s. The system
displays a message asking you whether the setting is to be saved in the EEPROM.
If you press "Yes", the system saves the setting in the EEPROM. If you press "No", the
setting is not saved permanently and the "S" starts flashing to indicate this fact.
In both cases, all changes that have not yet been saved permanently are stored in the
EEPROM.
