● For SIMOTION D: in HW Config, double-click on SINAMICS Integrated
● Under DP slave properties, in the tab Cycle synchronization read off the value Ti
During the measuring input configuration of "global" measuring inputs, also enter the negated
value of Ti as offset value of the time stamp (TimeStampConfig.correctionTime).
If measurements have to be performed with "very high" accuracy or the dead times caused by
the filter time constant and delay times from the transmission line, BERO, converter, contacts,
etc. cannot be ignored, we recommend the machine-specific determination of the dead times
that really occur, through measurements or series of measurements.
Measurements with velocity-dependent displaced measuring results are an indication that the
dead times have not been compensated or incorrectly compensated.
The procedure for empirical/measuring technique determination of dead times is similar to the
process for determining dead times during cam output.

Measuring input defaults
You can define the defaults for every measuring input. These values are stored in system
variables and can be changed by programs.
Double-clicking in the project navigator below the measuring input on the Defaults element
displays the window in the working area.
