This is an environmentally friendly design that complies with the hazardous substances *1 of the European revised RoHS (Restriction on the Use of Specific Hazardous Substances) and the hazardous substances *2 of the Chinese RoHS (Electronic Information Products Production Pollution Prevention Control Act).

*1: Lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl (PBB), polybrominated diphenyl ether (PBDE), Di-2-ethylhexyl phthalate (DEHP), butylbenzyl phthalate (BBP), di-n-butyl phthalate (DBP), Diisobutyl phthalate (DIBP)

*2: Lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl (PBB), polybrominated diphenyl ether (PBDE)

Harmonic suppression

All models of servo amplifiers used by specific consumers are subject to the "Japanese Guideline for Suppressing Harmonics by Customers Receiving High Voltage or Special High Voltage". All users required to apply guidelines must calculate equivalent capacity as well as harmonic outflow current based on these guidelines, and take appropriate measures if the calculated harmonic current exceeds the limit stipulated for the contracted wattage.

Circuit classification	Circuit type	Reactor	Conversion factor
3	3-phase bridge (capacitor smoothing)	Not equipped	3.4
		Equipped (on AC side)	1.8
		Equipped (on DC side)	1.8
		Equipped (on AC and DC sides)	1.4
4	Single-phase bridge (capacitor smoothing)	Not equipped	2.9
4	Single-phase bridge (capacitor smoothing)	Equipped (on AC side)	1.3

For information on how to calculate the harmonic current, use the following as a reference.
