This operating mode requires a motor encoder with MTTF ≥ 10 years.
The motor encoder is already included in the characteristic data, so no
more calculations need to be performed for the "Safe Actuator" subsys-
tem.

The safety-related characteristic data is valid for all safety functions.
All the units used within a safety function must be considered when cal-
culating the safety characteristic data.
