12-1 Overview of Optional Equipment

This section provides an overview of the optional equipment available with the 3G3RX-V1 Series
Inverter. For details, refer to the manual for each optional product.

12-1-1 Part Names and Descriptions

Regenerative Braking Unit (Model: 3G3AX-RBU)/
Braking Resistor (Model: 3G3AX-RBA/RBB/RBC)
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/+2, RB)/ Regenerative Braking
Unit Connection Terminal (P/+2, N/–) on page 2-39.
DC Reactor (Model: 3G3AX-DL)/
AC Reactor (Model: 3G3AX-AL)
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 2-20 and Harmonic Current
Measures and DC/AC Reactor Wiring (+1, P/2) on page 2-34.
Input Noise Filter (Model: 3G3AX-NFI)
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 2-33.
Output Noise Filter (Model: 3G3AX-NFO)
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 2-37.
Radio Noise Filter (Model: 3G3AX-ZCL)
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 2-38.
