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.
Our product, AC servo, has specific functions, but is not sold directly to general
consumers, i.e. this product is regarded as a component that constitutes a machine or
equipment. Therefore, the product (AC servo) is not required 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 driver 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 drivers and servo motors.
