Siemens SINAMICS Series Operating Instructions Manual page 345

In the following cases, each optimization run is completely executed again after a restart:
● If a fault occurs during the optimization run
● If the electronic supply is switched off prior to restarting the optimization run in question
● If a different drive data set from the previous one is selected
● If a different optimization run is started in the meantime
The parameters for the drive data set that has been selected in each case are optimized.
The drive data set selection must remain the same throughout the optimization runs to avoid
a fault being output.
