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)
