Safety Functions Integrated in the Drive
Note
This chapter describes the safety functions that are integrated in the drive – "Safe
Torque Off" (STO), "Safe Brake Control" (SBC) and "Safe Stop 1" (SS1), which are
controlled via the drive terminals. The safety functions SH and SBC from the
context of the safety–related motion monitoring functions are described in Chapter
6 "System/drive–integrated safety functions". The SS1 safety function essentially
corresponds there to STOP B. Control via terminals and from the motion
monitoring functions is in parallel and can be used independently of one another.

In this chapter, the NCU/NX is designated as "Control Unit".
Two–channel monitoring structure
All the main hardware and software functions for Safety Integrated are imple-
mented in two independent monitoring channels (e.g. shutdown signal paths, data
management, data comparison).
The two drive monitoring channels are implemented as follows:
S via the Control Unit
S via the Motor Module/Power Module belonging to a drive.
The monitoring functions in each monitoring channel work on the principle that a
defined status must prevail before each action is carried out and a specific
acknowledgement made after each action.
