EC Directives (CE Marking)

13.1

General description

• EC Directives were issued to standardize the regulations of the EU countries and ensure smooth distribution

of safety-guaranteed products.
EU countries make it mandatory that products sold in the EU countries meet the basic safety requirements
specified in the Machinery Directive (effective in January, 1995), EMC Directive (effective in January, 1996)
and LVD Directive (effective in January, 1997) among EC Directives and get attachment of the CE mark (CE
marking).
The CE marking is applicable to tension controllers with self-declaration of conformity to the EMC Directive
and LVD Directive, actuators (such as powder clutches/brakes, AC servo amplifies and vector inverters)
combined with such tension controllers and machines and systems in which sensors (tension detectors) are
incorporated.

• Powder clutches/brakes and tension detectors are not direct targets of the EMC Directive, but it is confirmed

that the tension controller LE-30CTN combined with a powder clutch/brake and tension detector conforms to
the EMC Directive.
Machines and systems incorporating such products are regarded as targets of the EMC Directive, and should
get attachment of the CE mark.
This chapter explains the installation method and measures to achieve the electromagnetic compatibility so
that machines and systems incorporating the LE-30CTN, powder clutch/brake (, AC servo amplifier or vector
inverter) and tension detector can easily conform to the EMC Directive.

• We have performed confirmation tests for conformity to the EMC Directive using representative models in the

environment based on the installation status described here, but cannot confirm the conformity in the actual
use situation.
The electromagnetic compatibility varies depending on the control box configuration incorporating the LE-
30CTN, the relationship with other incorporated electric products, wiring status and layout status. Each user
should confirm the electromagnetic compatibility of the entire machine or system.

13.2

EMC Directive

The EMC (Electromagnetic Compatibility) Directive mainly regulates the following two abilities.

(1) Emission (EMI: Electromagnetic Interference)

Ability not to release interference noise which gives adverse impact to the outside

(2) Immunity (EMS: Electromagnetic Susceptibility)

Ability to avoid malfunction caused by interference noise coming from the outside

Each of the above abilities can be classified as shown in the table below.
The contents of standards and tests required in final machines and systems are almost equivalent.
