SINUMERIK Safety Integrated
”SINUMERIK Safety Integrated” offers type–tested safety functions which allow
highly effective personnel and machine protection to be implemented in–line
with that required in practice.
All safety functions satisfy the requirements specified in 954–1, Category 3,
Performance Level d in accordance with EN ISO 13849–1, SIL 2 in accordance
with EN 61508 and are a standard part of the base system.
Neither additional sensors nor evaluation units are required; this means lower
installation time and costs at the machine and a ”low profile” electrical cabinet.
The function scope includes, e.g.:
Safety–relevant monitoring of velocity and standstill (zero speed)
Safety–relevant traversing range demarcation and range identification/
detection

Using the additional, integrated functions in the safety package ”Safety Integra-
ted” for SINUMERIK 840D/611D, for the first time, it is also possible to directly
connect two–channel I/O signals – for example, an Emergency Stop button or
light barriers. Logic operations and responses are performed internally using
safety–related technology.
All safety–relevant faults/errors in the system always cause potentially hazard-
ous movement to be brought to a standstill or the motor to be contactlessly dis-
connected from the line supply. The drives are brought to a standstill in the opti-
mum way, adapted to the operating conditions of the machine. This means, for
example, in the setting–up mode with the protective door opened it is possible
to stop axes as quickly as possible path–related – and also in the automatic
mode with closed protective door.
This means: High degree of protection for personnel in the setting–up mode and
additional protection for the machine, tool and workpiece in the automatic mode.
The safety functions provide a previously unknown, intelligent and direct link
right through the system to the electric drives and measuring system. Reliable
operation, fast response and wide acceptance mean that this certified safety
concept is extremely effective.
A two–channel, diverse system structure has been formed on the basis of the
existing multi–processor structure. The safety functions have been configured
redundantly in the NC, drive and internal PLC. A feature of this safety concept is
that a measuring system, the standard motor measuring system, can already
satisfy the safety requirements. A second sensor is not necessary but can be
added as an additional, direct measuring system, e.g. linear scale.
It has been clearly seen that new practical machine operation concepts can be
implemented with this innovative safety technology. The result is a new stan-
dard for machines which makes them safer and more flexible to use and which
increases the availability of the entire plant.
