11.13 Power factor improving DC reactor
POINT
For the 100V power supply type (MR-J3- B1), the power factor improving DC
reactor cannot be used.
The power factor improving DC reactor increases the form factor of the servo amplifier's input current to
improve the power factor. It can decrease the power supply capacity. As compared to the power factor
improving AC reactor (FR-BAL), it can decrease the loss. The input power factor is improved to about 95%.
It is also effective to reduce the input side harmonics.
When connecting the power factor improving DC reactor to the servo amplifier, always disconnect P
1
and P
2
(For 11kW or more, disconnect P
1
and P). If it remains connected, the effect of the power factor improving DC
reactor is not produced.
When used, the power factor improving DC reactor generates heat. To release heat, therefore, leave a 10cm or
more clearance at each of the top and bottom, and a 5cm or more clearance on each side.

11.14 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%.
In addition, it reduces the higher harmonic of input side.
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.
