Safe brake control (SBC)
In this figure normal and safe brake controls are connected in series. Both are
independent and redundant 2-channel solutions.
The safe brake control needs a feedback from the brake system. The SBC feedback
can be from a relay/contactor or from the mechanical brake itself.
Note: If also the drive can control the brake, the feedback must not be from the
mechanical brake.
