Note
: all values quoted in this table are valid only when the two STO user inputs are driven independently. This is as required by EN ISO
13849-1 category 3. See the Alignment to European Standards section in this chapter for the required architecture which must be used
throughout the machine design relevant to the drive under consideration.

EN ISO13849 limits MTTFd to 100 years.
2
A detected fault in the STO circuit causes STO to become active, and remain active until after a power cycle.
