IB-1501613-A
For details of the drive section (servo/spindle drive unit), refer to the "EMC Installation Guidelines" of instruction manuals for
each drive unit.
40.1 Introduction
EMC Directives became mandatory as of January 1, 1996. The subject products must have a CE mark attached indicating
that the product complies with the Directives.
As the NC unit is a component designed to control machine tools, it is believed that it is not a direct EMC Directives subject.
However, we would like to introduce the following measure plans to back up EMC Directives compliance of the machine tool
as the NC unit is a major component of the machine tools.
 Methods of installation in control/operation panel
 Methods of wiring cables to outside of panel
 Introduction of members for measures
Mitsubishi is carrying out tests to confirm the compliance to the EMC Directives under the environment described in this
manual. However, the level of the noise will differ according to the equipment type and layout, control panel structure and
wiring lead-in, etc.
Thus, we ask that the final noise level be confirmed by the machine manufacturer.
40.2 EMC Directives
The EMC Directives largely regulate the following two items.
 Emissions: Capacity to prevent output of interference noise that adversely affects external devices.
 Immunity: Capacity to not malfunction due to interference noise from external source.
The details of each level are classified in the table below.
It is assumed that the Standards and test details required for a machine tool are the same as these.
