Safety Integrated Basic Functions via PROFIsafe and terminals
Control of the Basic Functions via terminals on the Control Unit and on the Motor/Power
Module (parameters p9601.0 = p9801.0 = 1) may be enabled in parallel. In this way, the
STO and SS1 functions (time controlled) can be selected via PROFIsafe telegram 30 as well
as in parallel via the onboard terminals of the Control Unit and Motor Module/Power Module.
STO has priority over SS1, i.e. if SS1 and STO are simultaneously initiated, then STO is
executed.
