11-1 Overview of Optional Equipment
This section provides an overview of the optional equipment available with the 3G3RX2 Series Inverter.
For details, refer to the manual for each optional product.
These products absorb the regenerative energy generated when a load decelerates or an elevating
axis descends to prevent overvoltage trip of the inverter.
For details, refer to External Braking Resistor Connection Terminal (P, RB)/ Regenerative Braking Unit
Connection Terminal (P, N) on page 2-55.
Use these reactors to suppress harmonics generated from the inverter.
The AC reactor is used when the power supply voltage unbalance factor is 3% or more, the inverter
capacity is 500 kVA or more, or rapid change in the power supply voltage occurs to reduce its effect.
The DC/AC reactor also has an effect of improving the power factor.
For details, refer to 2-3-4 Wiring for Main Circuit Terminals on page 2-32 and Harmonic Current Mea-
sures and DC/AC Reactor Wiring (PD, P) on page 2-49.
Use this filter to reduce the conductive noise generated in the inverter and transmitted to power supply
lines.
For details, refer to Installing Input Noise Filter on page 2-48.
Use this filter to reduce the conductive noise generated in the inverter and transmitted to the motor side
wires.
For details, refer to Installing Output Noise Filter on page 2-53.
Use this filter to reduce the radiated noise generated in the inverter and emitted from the power-supply
line side and motor side wires.
For details, refer to Measures against Radio Noise on page 2-53.
