8 Electromagnetic Compatibility (EMC)
The electromagnetic compatibility (EMC) or electromagnetic interference
(EMI) includes the following requirements:
• sufficient noise immunity of an electric installation or an electric device
against external electric, magnetic or electromagnetic interference via
lines or through air
• sufficiently low noise emission of electric, magnetic or electromagnetic
noise of an electric installation or an electric device to other
surrounding devices via lines or through air
8.1 Ensuring the EMC Requirements
On the European level there are the EU directives. In the EU states these
directives are transformed into laws valid on a national level. The relevant
directive for EMC is EU directive 89/336/EWG which was transformed on
the national level in Germany into the law EMVG ("Law concerning
electromagnetic compatibility of devices") of 1992-11-09.
Drive and control components by Rexroth are designed and built, in
accordance with the present state-of-the-art of standardization, according
to legal regulations of the EU directive 89/336/EWG and the German
EMC law.
The compliance with EMC standards was tested by means of a typical
arrangement with a test setup conforming to standard with the indicated
mains filters. The limit values according to product standard EN 61800-3
have been complied with.
Apart from the internal test at the factory, a conformity test was carried
out for individual drive systems in an accredited laboratory of a CE-
responsible authority.
Measurements of the drive system with an arrangement typical for the
system are not in all cases applicable to the status as installed in a
machine or installation. Noise immunity and noise emission are strongly
depending on
• configuration of the connected drives
• number of the connected drives
• conditions of mounting, mounting site
• radiation conditions, wiring
• installation of individual drive components
in the machine or installation.
In addition, the required measures depend on the requirements of electric
safety technology and economic efficiency in the application.
In order to prevent interference as far as possible, notes on mounting and
installation are contained in the application manuals of the components
and in this documentation.
Note: Observe the descriptions and notes in chapter.
For EMC requirements we distinguish noise emission and noise immunity.
