SIMOVERT MASTERDRIVES Compendium Motion Control 3-1
3 Instructions for Design of Drives in
Conformance with EMC Regulations
3.1 Foreword
The modular design of SIMOVERT MASTERDRIVES permits a large
number of possible drive converter/equipment combinations so that it is
not practical to provide a separate description for every individual
combination here. It is more purposeful for this document to provide
basic information and generally applicable rules so that you can
configure your particular drive converter/equipment combination in an
"electromagnetically compatible" manner.
The drives are operated in widely varying environments and any
additionally used components (control systems, switch-mode power
sections, etc.) can differ considerably as far as their noise immunity and
noise emission levels are concerned. For this reason, it is permissible
to deviate from the EMC regulations on a case-to-case basis after
individual investigation.
In the context of the EMC Law, SIMOVERT MASTERDRIVES are
considered as "components" rather than "units". For a better
understanding of these instructions, however, the generally used term
"units" is used.
With effect from June 1996, the "EMC product standard including
special test methods for electric drive units" EN 61800-3 (VDE 0160
T100, IEC 1800-3) is applicable for frequency converters. Before this
product standard came into force, the standards EN 50081 with
EN 55011 and EN 50082 with IEC 801 were applicable. These are no
longer relevant for frequency converters now that the product standard
has come into force.
Please contact your local Siemens office regarding any other queries
you may have relating to EMC.
