Selecting safety function when a safety function is active
The table below lists the notes regarding the behavior of your drive if you select more than
one safety function at the same time.
Some cases do not affect the behavior of your drive. If, for example, the safety function STO
is active, the motor torque remains switched off regardless of which inverter function you also
select.
