Checking the checksum
For each monitoring channel, the safety parameters include one parameter for the
actual checksum for the safety parameters that have undergone a checksum
check.
During commissioning, the actual checksum must be transferred in the corres-
ponding parameters of the specified reference checksum. This can be done for all
checksums of a drive object at the same time with parameter p9701.
Basic Functions
S r9798 SI actual checksum SI parameters (Control Unit)
S p9799 SI reference checksum SI parameters (Control Unit)
S r9898 SI actual checksum SI parameters (Motor Module)
S p9899 SI reference checksum SI parameters (Motor Module)
Each time the system boots (powers up), the actual checksum is calculated using
the safety parameters and then compared with the 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 versions on the Control Units and on the Motor Modules have
their own version ID.
For the basic functions:
S r9770 SI Version safety functions integrated in the drive (Control Unit)
S r9870 SI version (Motor Module)
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 for
the drives.
S When Safety Integrated is commissioned for the first time, the following applies:
-- Safety password = 0
-- Default setting for p9761 = 0
This means:
The safety password does not need to be set during initial commissioning.
