14.12 Power factor improving reactors
The power factor improving reactors improve the phase factor by increasing the form factor of servo amplifier's
input current. It can reduce the power capacity. The input power factor is improved to be about 90%. For use
with a 1-phase power supply, it may be slightly lower than 90%.
When using power factor improving reactors for two servo amplifiers or more, be sure to connect a power factor
improving reactor to each servo amplifier. If using only one power factor improving reactor, enough
improvement effect of phase factor cannot be obtained unless all servo amplifiers are operated.
