The following are not deleted:
●
CU operating hours counter
● CU temperature and
● Safety logbook
At the end of the deletion, the initialization data of the applications is in the NVRAM, similar to
after a device automatic commissioning (with the exception of the above-mentioned data).
Parameter p7775 is set to 0 at the end of the deletion.
Explanations for the parameter p7775
The following jobs can be set with the parameter p7775:
Value of the parameter p7775 Job
1 Backup NVRAM data (on CompactFlash card)
2 Restore NVRAM data (from CompactFlash card)
3 Delete NVRAM data on the Control Unit
The acknowledgement of a parameter job is delayed.
●
If the job cannot be executed, it is acknowledged negatively.
● If the job can be executed, it is acknowledged with the value 255.

ment
Description
17 Request cannot be executed because of the operating state
20 Illegal value
107 Write access is not permitted (cause: At least one DO has a pulse enable)
Because
the SINAMICS must perform a warm restart when restoring and deleting the
data, none of the connected drives may have a pulse enable.
132 Parameter change blocked (see p0300, p0400, p0922, p7760, macro being executed)
204 Write access not permitted
255 "OK": Job being executed
If an error is detected during the execution of a parameter job, the error cause is signaled via
the parameter itself (no message via the fault buffer).
