Improve the Power Factor
AC reactors and DC reactors decrease surges in current and improve the power factor on the input side of the
drive. Connect an AC reactor or a DC reactor to the input side (primary side) in the these conditions:
•
To decrease harmonic current or improve the power factor of the power supply
•
When there is switching of phase advancing capacitor
•
With a large capacity power supply transformer (600 kVA or more).
Note:
•
You can use an AC reactor and DC reactor together.
•
When you connect a thyristor converter (for example, a DC drive) to the same power supply system, you should use an AC reactor,
regardless of the conditions of the power supply.
•
The main circuit terminal block for the drive, and the terminal blocks for the AC and DC reactors come in different shapes. Use
caution when you prepare the ends of the wires.
◆
Connect an AC Reactor
Note:
When you connect an AC reactor to the output side (secondary side) of the driver, set
C6-02 = 1 [Carrier Frequency Selection = 2.0
kHz]
.
A - Power supply
B - MCCB
C - AC reactor
D - Drive
Figure 3.40 AC Reactor Connection Example
◆
Connect a DC Reactor
When you install a DC reactor, remove the jumper between ter1 and +2. If you will not use a DC link
choke, do not remove the jumper.
A - Power supply
B - MCCB
C - Drive
D - DC reactor
Figure 3.41 DC Reactor Connection Example
Note:
You cannot connect a DC reactor to drive models B001 to B018.
