Password for fail-safe functions
Four parameters are assigned to the password protection system:
●
r9760 - Shows the currently valid password for fail-safe function parameters.
●
P9761 - Used to enter the password.
●
P9762 - Used to enter a new password (5 digits without leading zeros (0)).
●
P9763 - Used to confirm a new password.
When a password is entered (5 digits without leading zeros), it is compared to the password
stored in r9760.
If it is correct, i.e., if the two passwords match, access is granted.
If the password is incorrect, the parameters for fail-safe functions are disabled and the user
has to exit the commissioning mode for fail-safe functions manually using parameter
P3900 = 11. Parameter P3900 = 11 clears all previous changes that have been made to the
parameters for fail-safe functions.
Checksums
All parameters for fail-safe functions are verified with the aid of checksums, which guarantee
the integrity of the data stored in the drive processor's memory.
There are four checksums, two for each processor:
●
r9798 - Current checksum for P1
●
P9799 - Reference checksum for P1
●
r9898 - Current checksum for P2
●
P9899 - Reference checksum for P2
