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" subsystem.

The safety­related characteristic data is valid for all safety functions.
All the units used within a safety function must be considered when calculating the safety
characteristic data.

The characteristic data is valid when using a motor encoder with an MTTF ≥ 57 years.
The motor encoder is already included in the characteristic data, so no more calculations
need to be performed for the "Safe Actuator" subsystem.
