10.3 Safety logbook
Description
The "Safety Logbook" function is used to detect changes to safety parameters that affect the
associated CRC sums. Cyclic redundancy checks 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 fault messages. In addition to functional safety changes, safety
changes as a result of hardware being replaced can be detected when the cyclic redundancy
check has changed.
The following changes are recorded by the safety logbook:
● Functional changes are recorded in the checksum r9781[0]:
– Functional cyclic redundancy checks of the motion monitoring functions (p9729[0...1]),
axial (Extended Functions)
– Functional cyclic redundancy checks of the basic safety functions integrated in the
drive (p9799, SI setpoint checksum SI parameters CU), axial
– Functional cyclic redundancy checks of the TM54F (p10005[0]), global (Extended
Functions)
– 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 cyclic redundancy check of the motion monitoring functions
(p9729[2]), axial (Extended Functions)
– Hardware-dependent cyclic redundancy check of the TM54F (p10005[1]), global
(Extended Functions)
