Conformance to EC Directives/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 servo meet the EC Directives for Low Voltage Equipment so that the machine or equipment
comprising our AC servo 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.
