The safety related parts of robot and controller are e.g. the following stop circuits:
• Enabling device
• Emergency stop on operator panel
• Emergency stop on FlexPendant
• Limiting robot motion
• Protective stops
• SafeMove2
For the overall design and structure, the category 3 has been verified and meeting
the requirements of CCF.
Each of the stop circuits includes different components like enabling switch, panel
board, contactor board, relays etc. For each of these the MTTF
D
and DC have been
calculated according to EN ISO 13849-1 Annex C, D and E resulting in the values
as specified in the following table.
See the SISTEMA/ABB FSDT libraries for details of the safety functions.
