CHAPTER 0 INTRODUCTION
■ Compliance with EU directives
0
EU directives aim at integration of regulations among the EU member countries to promote
distribution of safety assured products. It is required to satisfy basic safety requirements including
machine directive (enacted in January 1995), EMC directive (enacted in January 1996), and low
voltage directive (enacted in January 1997) and affix a CE mark (CE marking) on the product sold in
EU member countries. Machines and devices housing the servo system are subjected to CE
marking.
The servo system does not function independently but is a component to be used in combination
with machines and equipments. For this reason, the servo system is not applicable to the EMC
directive but the machine or equipment including the servo system is applicable.
In order to facilitate CE marking declaration on the assembly machine or equipment of the servo
system, optional devices that are compliant with the low voltage directive and that support compliant
with the EMC directive as well as a relevant guideline are prepared.
■ Compliance with RoHS directive
RoHS directive concerns with toxic materials and it was made into effective on July 1, 2006 in the EU
member countries. The directive prohibits inclusion of toxic materials in electric and electronic
devices. Regulated materials include Pb (lead), Cd (cadmium), Cr6+ (hexavalent chromium), Hg
(mercury), PBB (polybromobiphenyl), PBDE (polybromobiphenyl ether).
This servo system is compliant with the RoHS directive.
The color (screw color, etc.), gloss and material may be different from those of conventional products
in order to comply with the RoHS directive, but will not cause an effect in the performance and
specifications.
■ Service life of EEPROM
This product is equipped with EEPROM for retaining parameter data in the event of power failure.
The write enable frequency of EEPROM is about 100,000 cycles. After the following operation is
repeated 100,000 times or more, the risk of the servo amplifier failure becomes higher.
