8.9.3 Safety logbook
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 drive-
integrated functions CPU 1/2) 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 fault messages. 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]:
– Functional CRCs of the motion monitoring functions (p9729[0]), axial (Extended
Functions)
– Functional CRCs of the drive-integrated Basic Safety functions (p9799, SI setpoint
checksum SI parameters (Control Unit)), axial
– Enabling of functions integrated in the drive (p9601), axial (Basic and Extended
Functions)
● Hardware-dependent changes are recorded in the checksum r9781[1]:
– Hardware-dependent CRC of the motion monitoring functions (p9729[2]), axial
