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 it has been tested for radiated immunity up to 3GHz which
includes frequencies used by mobile telephones and walkie-talkies.
