STO active
Set if the STO safety function is active and torque/force is removed from the drive.
The activation may be a result from a demand of the Safety Application Process of a
fault reaction from a fault in the safety fault buffer or a demand from the PROFIdrive
on PROFIsafe Safety Function State Machines.
Cleared if the STO safety function is inactive and torque/force may be generated
from the drive.
This bit can also be accessed via UPID 1A06h bit 0.
