17.1.164.1 Definition of the switching range
Depending on the setting of the CenterMode (C01064/x), the switching range can be defined via a
start and end position or via the data of the center point/size of switching range:

17.1.164.2 Dead time compensation
The delay time of external switching elements can be compensated by setting the corresponding
delay time in C01062/x
. From this input and the current speed ,the FB calculates a preliminary stop,
i.e. the bOut switching output is set correspondingly earlier.
