Safety logbook

Description
The "Safety Logbook" function is used to detect changes to safety parameters that affect the
associated CRC sums. CRCs are only generated when p9601/p9801 (SI enable, functions
integrated in the drive CU/Motor Module) is > 0.
Changes to data can be detected when the CRCs of the SI parameters have changed. Each
SI parameter change that is to become active requires the reference CRC to be changed so
that the drive can be operated without SI fault messages. The following changes are
recorded by the safety logbook:
● Functional changes are recorded in the checksum r9781[0]:
Overview of important parameters (see SINAMICS S List Manual)
● r9781[0] SI checksum to check changes (Control Unit), functional
● r9782[0] SI time stamp to check changes (Control Unit), functional
● p9799 SI reference checksum SI parameters (Control Unit)
● p9601 SI enable, functions integrated in the drive (Control Unit)
● p9801 SI enable, functions integrated in the drive (Motor Module)
