Conformance to EC Directives and UL Standards

EC Directives

The EC Directives apply to all such electronic products as those having specific functions and directly
sold to general consumers in EU countries. These products are required to meet the EU unified standards
and to be furnished with CE Marking.
However, our AC servos meet the EC Directives for Low Voltage Equipment so that the machine or
equipment comprising our AC servos can meet relevant EC Directives.

EMC Directives

Our servo systems can meet EMC Directives and related standards. However, to meet these requirements,
the systems must be limited with respect to configuration and other aspects, e.g. the distance between the
servo amplifier and motor is restricted, and some special wiring conditions must be met. This means that
in some cases machines and equipment comprising our servo systems may not satisfy the requirements
for wiring and grounding conditions specified by the EMC Directives. Therefore, conformance to the EMC
Directives (especially the requirements for emission noise and noise terminal voltage) should be examined
based on the final products that include our servo amplifiers and servo motors.
