CYCLE755 - Backup/restore data

At the start of an optimization session (with the call of CYCLE751), the system creates a backup
file that permits an automatic data restoration in a fault situation or after an abort. The user
can also invoke CYCLE755 to create user-specific backup files in the file system that permit
the backup of the current data and so a specific data restoration at anytime during the
optimization session, e.g. to discard data changes that should not be accepted. The data
restoration is also made with CYCLE755.

Special functions
Function Manual, 01/2015, 6FC5397-2BP40-5BA2
Specifies whether the specified axis or drive data set should be added to or removed from the data
set list.
INT
0 = Not defined
1 = Add a data set
2 = Remove a data set
3 = Remove all data sets from the list
Note:
If the list is empty, the optimization results can be written only to the active data set.
Data set type
INT
0 = Not defined
1 = Axis data set (servo parameter set)
2 = Drive data set (DDS)
Data set index
Specifies the data set to be added and into which the optimization results should be written or should
be removed from the list.
Note:
For the axis data set index: <n> = parameter set number - 1
Example: Index 0 ≙ parameter set 1
-1 = active data set
