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 (Control Unit)
● p9799 SI reference checksum SI parameters (Control Unit)
● r9898 SI actual checksum SI parameters (Motor Module)
● p9899 SI reference checksum SI parameters (Motor Module)
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 differ, fault F01650/F30650 or F01680/F30680 is
output and an acceptance test requested.
Safety Integrated versions
The Safety firmware has a separate version ID for the Control Unit and Motor Module.
For the Basic Functions:
● r9770 SI version, drive-autonomous safety functions (Control Unit)
● r9870 SI version (Motor Module)
