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.

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