7.1 Safety-relevant input/output signals
Note
The state of a deleted SGE/SGA (logical "0") that can be achieved both by the
user as well as also using fault responses of the "SINUMERIK Safety Integrated"
system, are defined as so-called "fail-safe state" of an SGE/SGA. This is the
reason that the system is only suitable for applications where this state
corresponds to the fail-safe state of the process controlled by "SINUMERIK Safety
Integrated".
Which SGEs/SGAs are there?
For each axis/spindle, the following SGEs and SGAs are in each monitoring chan-
nel:
