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.
EMC Specification
In addition to the mandatory requirements of EN61800, the STO functionality has been subjected to testing for immunity at higher levels. In particular
the STO function (only) has been tested for radiated immunity according to EN62061:2005 Annex E up to 2.7GHz which includes frequencies used by
mobile telephones and walkie-talkies.

EN ISO13849 limits MTTFd to 100 years.
