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.
Data changes are detected when the CRCs of the SI parameters change. 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 faults. In addition to functional safety changes, safety changes as
a result of hardware being replaced can be detected when the CRC has changed.
The following changes are recorded by the safety logbook:
● Functional changes are recorded in the checksum r9781[0]:
