5.5.6.4

Checksums

Description
All parameters for fail-safe functions are verified by the use of checksums. These checksums
ensure the integrity of the data held within the drive processors memory.
There are four checksum, two for each of the processors, these are:
● r9798 – actual checksum for P1.
● P9799 – reference checksum for P1.
● r9898 – actual checksum for P2.
● P9899 – reference checksum for P2.
