7.2 General Safety Information
The following subchapters contain general information for the safety functions, such as characteristics, boundaries,
constraints etc.
7.2.1 Boundary of the Safety Compliant System
The safety parts in the 2S system contain the following:
Safety related parts in the drive, such as
safe digital inputs
safe digital output
safe bus ID
safe position encoder
safe PROFIdrive
circuit for STO
circuit for SBC
Safety firmware on the safety Module SM
Safety related parts in the motor encoder electronics
7.2.2 Constraints of the use of the Safety Compliant System
The following constraints have to be regarded:
Safe Encoder:
A safe position encoder must be used for the safety function SOS, SS2, SLS and SBT.
The safety functions STO, SS1 and SBC can also be used with a non-safe position encoder.
Safe Brake:
The safe brake is not part of the safety compliant system.
The brake has to be designed in the application regarding the application specific requirements.
