The I&M data sets 1...3 are stored permanently in the parameters p8806...p8808. Essential
properties of these 3 parameters:
● They can be displayed in the STARTER expert list.
● The SINAMICS "Reset parameter" (p0976 = 1, p0970 = 1) function does not have any
effect on the content of parameters.
● I&M data sets are not changed when the alternative parameter sets are stored or loaded.
The transfer of parameter sets between a memory card and non-volatile device memory
does not have any effect on the I&M data sets.

signature has the following format:
The first four octets (0...3) contain the
•
content of parameter r9781 index 0:
"SI change monitoring checksum
(Control Unit)".
The second four octets (4...7) contain the
