The examples show the use of the 24V supply provided on X14/03 (+24V) and X14/04 (0V)
as source of power to a load. Alternatively an external 24V supply could be used.
Note: If a drive is powered from 24V only, i.e., 24V is applied to terminals X13/01 or X13/02
and the 3 phase power is off, the STO user output will still reflect the status of the two STO
user inputs.
