6.4 EMC installation guideline
6.4.1 Outlines
The EMC directive is coerced from January 1, 1996, and it is necessary to attach the CE mark which shows that
the product is in conformity to directive.
Since the industrial robot is the component of the automation system, it considers that the EMC directive is not
the target product of the direct. However, because it is one of the main components, introduces the method and
components of the measures for conforming the automation system to the EMC directive.
And also we are carrying out the qualification test about the conformity of the EMC directive under the environ
-
ment based on the contents of this document. However, the noise level is changed by the kind of equipment to be
used, the layout, the construction of the controlling board, the course of wiring, etc. Therefore, please confirm by
the customer eventually.
6.4.2 EMC directive
The Mitsubishi Electric industrial robot follows the European EMC directive. This technical standard regulates the
following two items.
(1) Emission (EMI Electromagnetic Interference)..............The capacity not to generate the disturbance noise
which has a bad influence outside.
(2) Immunity (EMS Electromagnetic Susceptibility)..........The capacity which does not malfunction for the dis
-
turbance noise from the outside.
Each contents are shown below.
