Resetting identification
The identification data can be reset manually with
PNU 1192:03. See section 5.4.16.
The adaptation data is also reset here.
Recommendation:
After exchanging components or changing parameters, the
identification data should be reset before carrying out a new
identification run.
Adaptation
After successful identification, the adaptation values are
automatically determined during operation.
Adaptation is able to independently improve non−optimal
control behaviour. The reason for poor control behaviour in
small tolerance windows are long−term effects and impre
cisely identified values.
Deactivating adaptation
Adaptation can be deactivated via the parametrisation. That
usually isn’t required in any configuration. Only
in extremely
rare cases does adaptation lead to worsened positioning be
haviour.
Important: Not every deterioration in the positioning behav
iour is due to faulty adaptation. Wear or weak construction
can also lead to the positioning times gradually being pro
longed, for example, or even the number of E30 messages
piling up. For this
reason, one should only deactivate adapta
tion if this is justified.
