You activate the respective parameter by setting the associated bit to 1.

For signal type "Absolute encoder (SSI)", the following applies: Reserved
3
In isochronous mode, the parameter can affect the isochronous mode parameters of the sync domain. Because the
4
isochronous mode parameters are not checked in RUN, overflows can occur if you change the parameter in RUN. To
prevent overflows, select the option with the largest time required in the offline parameter assignment.
Applies to: Set function of DI = 001
