to the List Manual.
When making changes to fail-safe functions, the following steps are mandatory:
Parameter Description
P0010 = 95 Commissioning parameter*
95: Commissioning of fail-safe functions
P9761 SI password input
These parameters are used to enter the security password nec-
essary for accessing and changing fail-safe function parameters.
Change the required fail-safe parameters and then follow the steps below to exit parameterization:
P9799 Checksum for SI parameters
Checksum of fail-safe function parameters.
Enter the value from r9798.
P9899 Checksum for SI parameters
Checksum of fail-safe function parameters.
Enter the value from r9898.
P3900 = 10 End of safety commissioning*
10: Accept changes to fail-safe function parameters.
11: Reject changes to fail-safe function parameters.
Parameters for fail-safe functions
The table below provides an overview of all the fail-safe function parameters. Access level 3
applies in respect of the fail-safe parameters (P0003 = 3). The values of fail-safe parameters
can only be changed with a password (P9761). For a more detailed description, please refer
to the List Manual.
