Checking the checksum
For each monitoring channel, the safety parameters include one parameter for the
actual checksum for the relevant safety parameters that have undergone a check-
sum check.
During commissioning, the actual checksum must be transferred in the corre-
sponding parameters of the specified reference checksum.
S r9798
S p9799
S r9898
S p9899
Each time the system boots, the actual checksum is calculated using the safety
parameters and then compared with the specified reference checksum.
If the actual and specified reference checksums are different, fault F01650 or
F30650 is output and an acceptance test requested.
Safety Integrated versions
The safety software integrated in the drive on the Control Unit and on the Motor
Modules each have their own version ID.
S r9770[0...2]
S r9870[0...2]
Password
Note
A password allocation is not relevant in the SINUMERIK environment. It is only
used in conjunction with Starter (commissioning tool used for SINAMICS).
The safety password protects the safety parameters against unauthorized write
access.
In the commissioning mode for Safety Integrated (p0010 = 95), you cannot change
safety parameters until you have entered the valid safety password in p9761.
S When Safety Integrated is commissioned for the first time, the following applies:
– Safety password = 0
– Default setting for p9761 = 0
In other words:
The safety password does not need to be set during initial commissioning.
