Einleitung
2.8 Realisierung komplexer Funktionen in einer Beispielprojektierung
C:\Program Files\Siemens\Step7\Examples\dcc\Examples_CRGE_TCLR.xml
Hinweis
Das Beispielprojekt ist auf Basis eines SCOUT-Projektes erstellt worden und beinhaltet daher
die Projektierungen sowohl für SINAMICS_Integrated als auch SINAMICS-standalone/
CU320. Beim Import des Beispielprojektes mit STARTER werden die SIMOTION-
Komponenten naturgemäß abgelehnt; die CU320-Komponenten werden jedoch weiterhin
korrekt importiert und sind kopierbar.

Command Priority:
from highest priority to lowest priority:
1. enamble ramp function generator / set to zero
2. quick stop ramp function generator
3. set ramp function generator to setpoint value
4. bypass ramp function generator
5. bring ramp function generator to standstill
6. stop ramp function generator

switching of drive data sets:

there is no switching of data sets available like in the sinamics.
CD
If there are di erent data sets necessary, the user has to add aditional
CF numerical switches to change between the di erent data sets.
