11.7 Power factor improving AC reactors
The power factor improving AC 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.
When using two different types of motors in combination from a rotary servo motor, a linear servo motor or a
direct drive motor, select a power factor improving AC reactor temporarily assuming that the same type of the
motors are used for both axes. After selecting for the two types, use the larger power factor improving AC
reactor.
