9.4.2 Ensuring the EMC Requirements
Standards and laws
On the European level there are the EU Directives. In the EU states these Di‐
rectives are transformed into laws valid on a national level. The relevant di‐
rective for EMC is EU Directive 2004/108/EC which was transformed on the
national level in Germany into the law EMVG (“Law concerning electromag‐
netic compatibility of devices”) of 2008-02-26.
EMC Properties of Components
Drive and control components by Rexroth are designed and built, in accord‐
ance with the present state-of-the-art of standardization, according to legal
regulations of the EU Directive EMC 2004/108/EC and the German law.
The compliance with EMC standards was tested by means of a typical ar‐
rangement with a test setup conforming to standard with the indicated exter‐
nal mains filters. The category C3 requirements according to product stand‐
ard EN 61800-3 have been complied with.
Applicability for End Product
Measurements of the drive system with an arrangement typical for the sys‐
tem are not in all cases applicable to the status in a machine or installation.
Noise immunity and noise emission strongly depend on:
● configuration of the connected drives
● number of the connected drives
● conditions of mounting
● site of installation
● radiation conditions
● wiring and 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 in‐
stallation are contained in the application manuals of the components and in
this documentation.
Cases to Distinguish for Declara‐
tion of EMC Conformity
For validity of the harmonized standards, we distinguish the following cases:
● Case 1: Delivery of the drive system.
According to the regulations, Rexroth drive systems are complied with
product standard EN 61800-3 C3. The drive system is listed in the dec‐
laration of EMC conformity. This fulfills the legal requirements according
to EMC directive.
● Case 2: Acceptance test of a machine or installation with the installed
drive systems.
The product standard for the respective type of machine/installation, if
existing, applies to the acceptance test of the machine or installation. In
the last years, some new product standards were created at present.
These new product standards contain references to the product standard EN
61800-3 for drives or specify higher-level requirements demanding increased
filter and installation efforts. When the machine manufacturer wants to put the
machine/installation into circulation, the product standard relevant to his ma‐
chine/installation has to be complied with for his end product “machine/instal‐
lation”. The authorities and test laboratories responsible for EMC normally re‐
fer to this product standard.
This documentation specifies the EMC properties which can be achieved, in
a machine or installation, with a drive system consisting of the standard com‐
ponents.
It also specifies the conditions under which the indicated EMC properties can
be achieved.
