Overview of Safety Function Parameters

4.4.1
Functional safety configuration is done in MyDrive® Insight, in Setup & Service > Functional safety > Safety configuration. Changing
parameters related to functional safety requires logging in as an admin.
Parameters related to application software, for example, automatic/manual restart behavior after STO deactivation, are included in
parameter group Functional Safety. Factory default values and other preset values are not valid for safety applications as such, and
all parameter values must be checked to ensure that the configuration is suitable for the application. For more information on setting
parameters, refer to application software documentation.
After initial startup and the modification of the configuration or functional safety parameters, a
IMPORTANT:
commissioning test must be performed to verify the functionality of individual safety functions. For more information,
see 4.8.4 Commissioning Test for Safety Function STO
controlled (SS1-t).
The configuration of functional safety features must be done according to the safety system installation and wiring, and consists of the
following steps:
1.
General parameter configuration
2.
Failure configuration
3. Safe fieldbus configuration
4. STO configuration
5.
SS1 configuration
6.
Saving to device
7. Parameter verification
8.
Validate report
9.
