1.0 Parameterizing the safety functions integrated in the drive
All of the steps necessary to commission the safety functions being used
are explained in this section.
The following describes how the safety functions are commissioned online.
Note
Offline commissioning is possible, however then slight deviations when
configuring must be observed. Further information on this topic is provided in the
Safety Function Manual (FHS), in Edition 01/1013 /1/.
Only the screen forms are shown here where changes have to be made.
