Uncommissioned data sets
Drive commissioning can also be completed if uncommissioned data sets (EDS, MDS, DDS)
are available.
Uncommissioned data sets are marked as "uncommissioned".
The attributes are displayed in STARTER or in the expert list or OPs.
Activation of these data sets is not permitted and will be rejected with an error.
Assigning these data sets to a drive data set (DDS) is only possible with a
commissioning step (p0009 ≠ 0, p0010 ≠0).
Note
If there is no DDS dataset with the attribute "commissioned", the assigned drive axis remains
in the controller inhibit.
