I&M 3: DESCRIPTOR
I&M 4: SIGNATURE
The I&M data sets 1...4 are stored permanently in parameters p8806...p8809. Significant
properties of these four 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 the 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.
Overview of important parameters (see SINAMICS S120/S150 List Manual)

parameters
p8808[0...53] Text with any comments or notes.
p8809[0...53] The parameter can be filled automatically
by the system, in which case it contains a
standard value, namely, a functional check
signature for the change tracking by
Safety Integrated. The check 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 content of parameter r9782 index
0: "SI change monitoring time stamp
(Control Unit)".
The remainder (octets 8...53) contains
•
zeroes.
Alternatively, a user can enter a user
value from an application and so overwrite
the standard value. Parameter p8805
specifies which value is entered in p8809:
p8805 = 0 standard value entered
•
p8805 = 1 user value entered
•
When p8805 = 0 is set, the standard
setting for p8809 is restored again.
