Connecting an Advanced-phase Capacitor or Thyristor-controlled Device to the Power Supply

An advanced-phase capacitor is not required for the converter. Installing an advanced-phase capacitor will reduce the
power factor.

If an advanced-phase capacitor currently exists is in the same power supply system as the converter, install a series reactor
on the advanced-phase capacitor to prevent resonance with the converter.

If a device that generates voltage surge or voltage distortion, such as a thyristor-controlled DC drive or electromagnetic
mixer is installed in the same power supply system as the converter, consult with your Yaskawa representative or the
nearest Yaskawa sales office.

Countermeasures for EMC and High-frequency (Harmonic) Leakage Current

Although countermeasures are not required for harmonic currents, the same countermeasures for electrical interference
(EMC) and high-frequency (harmonic) leakage current are required as for a normal drive. If there are nearby devices that
are easily affected by electrical interference, use a reactor-type noise filter (e.g., zero phase reactor).

When installing an MCCB or GFCI at the power supply, use an MCCB or GFCI that is designed for a drive (i.e., one that
has countermeasures for high-frequency leakage current).

Compliance with Harmonic Suppression Guidelines

• Guidelines for harmonic suppression measures are applicable to consumers that receive power from a 6.6 kV or higher

system. For details, refer to the Harmonics Suppression Technical Guideline JEAG 9702-1995.

• With respect to the harmonic suppression guidelines, the converter is equivalent to a three-phase bridge that does not

generate harmonics (K

5

= 0), but the harmonic component is not completely zero.

Impact of Power Supply Distortion

Distorting the power supply voltage and connecting several devices in parallel to the same power supply will cause power
supply system harmonics to flow into the converter and increase the harmonic content.

AVERTISSMENT

NPJT31470-1

Lire le manuel avant l'installation.

Attendre 5 minutes après la coupure

de l'alimentation, pour permettre

la décharge des condensateurs.

Pour répondre aux exigences , s

assurer que le neutre soit relié

à la terre, pour la série 400V.

Après avoir déconnécte la protection

entre le driver et le moteur, veuillez

patienter 5 minutes avain d’effectuer

une opération de montage ou de

câblage du variateur.

Risque de décharge électrique.

Surfaces Chaudes
