Saving The Fault Buffer When Switching Off - Siemens SINAMICS DCM List Manual

Saving the fault buffer when switching off

The contents of the fault buffer are saved to the non-volatile memory when the Control Unit is
switched off, i.e. the fault buffer history is still available when the unit is switched on again.
The fault buffer of a drive object comprises the following parameters:
• r0945[0...63], r0947[0...63], r0948[0...63], r0949[0...63]
• r2109[0...63], r2130[0...63], r2133[0...63], r2136[0...63]
The fault buffer contents can be deleted manually as follows:
• Delete fault buffer for all drive objects:
• Delete fault buffer for a specific drive object:
The fault buffer contents are automatically deleted when the following occurs:
• Restore factory setting (p0009 = 30 and p0976 = 1).
• Download with modified structure (e.g. number of drive objects changed).
• Power-up after other parameter values have been loaded (e.g. p0976 = 10).
• Upgrade firmware to later version.
