En 60204--1 - Siemens Sinumerik 840D sl Function Manual

Regulations and standards
1.2 Safety of machinery in Europe
1.2.7 EN 60204- - 1
European standard EN 60204--1 is based on the modified ISO edition of
IEC 60204--1. It includes general requirements and recommendations for the elec-
trical, electronic and programmable electronic equipment of machines with rated
voltages up to and including 1000 V AC/ 1500 V DC at rated frequencies up to and
including 200 Hz, in order to:
-- Promote the safety of persons and assets
-- Maintain the correct functioning
-- Simplify service and maintenance
The equipment, which is covered by EN 60204--1, starts at the point of connection
to the line supply of the electrical equipment of the machine and ends at the motor
shaft.
1.2.8 EN 61800- - 5- - 2
The European product standard EN 61800--5--2 has taken the international stan-
dard IEC 61800--5--2 without any changes.
It defines requirements and gives recommendations for designing and developing,
integrating and validating safety--relevant power drive systems with adjustable
speed (PDS(SR)) regarding their functional safety.
This standard is only applicable if the functional safety of a PDS(SR) is used and
the PDS(SR) is operated in a mode with a high number or continuous demand
(demand mode). The EN 61508 series of standards should be used for operating
modes with a low demand (low demand mode).
This part of EN 61800 discusses the safety--related evaluation of a PDS(SR) within
the framework of the EN 61508 series of standards and introduces requirements
placed on a PDS(SR) as subsystems of a safety--relevant system. This therefore
permits the implementation of the electrical/electronic/programmable electronic
(E/E/PE) elements of a PDS(SR) taking into account the safety--relevant perfor-
mance of the safety function(s) of a PDS.
Manufacturers and suppliers of PDS(SR) can prove to users (i.e. integrators of
control systems, developers of machines and plants etc.) the safety--relevant
performance of their equipment by implementing the specifications laid down in
EN 61800--5--2. When this part of EN 61800 is complied with, all of the require-
ments of the EN 61508 series of standards, which are specified for a PDS(SR),
are fulfilled.
This part of EN 61800 is only valid for PDS(SR), which implement safety functions
up to SIL 3.
The following basic requirements of the EC machinery directive are covered in
EN 61800--5--2:
S Safety and reliability of controls
S Faults in control circuits.
