Safety Integrated Functions
8.2 General information about SINAMICS Safety Integrated
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 to the corresponding
parameter for the reference checksum. This can be done for all checksums of a drive object
at the same time with parameter p9701.
Basic Functions
● r9798 SI actual checksum SI parameters (CPU 1)
● r9799 SI reference checksum SI parameters (CPU 1)
● r9898 SI actual checksum SI parameters (CPU 2)
● p9899 SI reference checksum SI parameters (CPU 2)
Extended Functions
● r9398[0...1] SI Motion actual checksum SI parameters (CPU 2)
● p9399[0...1] SI Motion reference checksum SI parameters (CPU 2)
● r9728[0...1] SI Motion actual checksum SI parameters
● p9729[0...1] SI Motion reference checksum SI parameters
During each ramp-up procedure, the actual checksum is calculated via the Safety
parameters and then compared with the reference checksum.
If the actual and reference checksums are different, fault F01650/F30650 or F01680/F30680
is output.
Safety Integrated versions
The Safety firmware on the Control Unit has a different version ID to that on the Sensor
Module.
For the Basic Functions:
● r9770 SI version, drive-autonomous safety functions (CPU 1)
For the Extended Functions:
● r9590 SI Motion version safe motion monitoring (CPU 1)
● r9890 SI version (Sensor Module)
Note
For detailed requirements regarding Safety Integrated firmware, see "Safety Integrated
firmware versions".
