Saving the parameters permanently
Description
If parameters have been 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.
In both cases, all changes that have not yet been saved permanently are stored in the
EEPROM.

Parameterization errors
If a fault occurs when reading or writing parameters, a popup window containing the cause of
the problem is displayed.
The system displays:
Parameter write error (d)pxxxx.yy:0xnn
and a plain-text explanation of the type of parameterization error.
