1321反射波减少(RWR)装置
反射波现象的描述
驱动器的逆变部分不产生正弦电压，而是由直流产生的一系列电压脉冲
公共汽车。这些脉冲沿着电机电缆传到马达，然后反射回驱动器。反射是
依赖于驱动输出电压、电缆特性、电缆长度和电机阻抗的上升时间。如果
电压反射与另一个脉冲相结合，峰值电压可能处于破坏性的水平。一个IGBT
驱动输出可能反映了两倍(2 pu或每单位)直流母线电压的波瞬态电压应力
自己的输出线。多个驱动输出线在一个管道或金属托盘进一步增加输出线电压应力
在多驱动器输出线之间的接触。驱动 1可能有一个(+)2 pu的压力，同时驱动器2可以同时
有(-)2 pu应力。

1321-3R, 1321-3RA, and 1321-3RB Series Line Reactors
Applying Allen-Bradley Line Reactors
At the Input of the Drive
At the input of a drive, line reactors help protect against surges or spikes on the
iing power lines and help reduce harmonic distortion.
At the Output of the Drive
In long motor lead applications, Allen-Bradley load reactors located been the
drive and motor help reduce dv/dt and motor terminal peak voltages. Thee of
a load reactor also helps protect the drive from surge currents ced by rapid
changes in the load.
With Multiple Drives
Multiple drives on amon power line should each have their own line
reactor. Individual line reactors provide filtering been each drive to help
reduce any crosstalk while providing optimum surge protection for each drive.
With Multiple Motors
When more than one motor is controlled by a single drive, a single line reactor
can typically beed been the drive and all the motors. Size the line reactor
based on the total motor/load horsepower.
With Single-Phase Input
A three-phase reactor can beed for single-phase applications by routing each
of theo input power conductors to the outsideo coils, and leaving the
center coil disconnected. The sum of the inductance of theo coils is the total
inductance applied to the circuit. Contact Rockwell Automation Technical
Support for assistance in specifying the proper reactor.

1321 Reflective Wave Reduction (RWR) Devices
Description of Reflected Wave Phenomenon
The inverter section of a drive does not produce sioidal voltage, but rather a series of voltage pulses created from the DC
. These pulses travel down the motor cables to the motor and then reflected back to the drive. The reflection is
dependant on the rise time of the drive output voltage, cable characteristics, cable length and motor impedance. If the
voltage reflection isbined with another subsequent pulse, peak voltages can be at a destructive level. A single IGBT
drive output may have reflected wave transient voltage stresses of up toice (2 pu or per unit) the DC voltage been
its own output wires. Multiple drive output wires in a single conduit or wire tray further increase output wire voltage stress
been multi-drive output wires that are touching. Drive #1 may have a (+) 2 pu stress while drive #2 may simultanely
have a (–) 2 pu stress.
