12.10 Power Factor Improving DC Reactor
POINT
For the 100VAC power supply type (MR-J3- A1), 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 the wiring
across P1-P2. 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.
