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

9.3.9

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 permanently. This
indicates that at least 1 parameter has been changed and not yet stored permanently.
2 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 the OK key, press it 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. Depending on the configuration, this can take from 45 s to several minutes. Also
refer to the "CompactFlash Card functions" chapter.
Note
During a data save operation initiated by the user, the electronics power supply for the
SINAMICS DC MASTER must not be interrupted.
An active saving process is indicated by the following actions:
• The RDY-LED flashes (see Chapter "AUTOHOTSPOT")
• The BOP20 flashes
Interrupting the power supply while saving can lead to the loss of the current device
parameter assignments. See also Chapter "AUTOHOTSPOT".
