Completion of the certificate
Document your machine's data for each drive based on the following specifications.
Parameters of the safety functions
The function test does not detect all faults in the parameter assignment of safety functions,
e.g. forced dormant error detection time or filtering time of fail-safe inputs. Therefore, check
all parameters once more.

Checksums of the safety functions
The converter calculates checksums across all parameters and safety functions.
When you change the safety function settings, the converter calculates new checksums.
This means that subsequent changes in your machine can be tracked.
In addition to the individual checksums of the parameters, the converter calculates and
saves the following values:
1. The "total" checksum across all checksums.
2. Time of the last parameter changed.
