5.5.5.3 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.
5.5.5.4 General Steps For Commissioning Fail-Safe Functions
Description
The parameters designated with an "*" offer more setting possibilities than are listed here.
Refer to the parameter list for additional setting possibilities.
The following steps must always be carried-out when changing fail-safe functions:
Parameter Description Unit Default Min. Max.
P0003 = 3 User access level*
3: Expert: For expert use only
1 0 4
P0010 = 95 Commissioning parameter*
95: Commissioning the fail-safe functions
0 0 95
P9761 SI input password
The safety password is entered in this parameter to get access to
change fail-safe function parameters.
- 12345 1000 99999
Change requested fail-safeparameters, then finish the parameterization with the following steps:
P9799 Checksum for SI parameters
Checksum of the fail-safe function parameters.
Enter value of r9798
- 000h 000h FFFFh
P9899 Checksum for SI parameters
Checksum of the fail-safe function parameters.
Enter value of r9898
- 000h 000h FFFFh
P3900 = 10 End of the safety commissioning*
10: Accept changes of fail-safe function parameters
11: Cancel changes of fail-safe function parameters
