What This Publication
Provides This publication provides layout, sizing, wiring, startup and
diagnostic information for the 1336 REGEN Line Regeneration
Package, including Converter, Precharge Unit, 1321 Line Reactor,
and Line Filter (when required). To ensure successful installation
and operation, the material presented must be thoroughly read and
understood before proceeding. Particular attention must be
directed to the Attention and Important statements contained
within.
What This Product
Provides The Allen-Bradley 1336 REGEN Line Regeneration Package is a
line regenerative option for drives in the Allen-Bradley 1336 drive
family. Line regeneration refers to the removal of energy from the
common DC bus of one or more AC drives, back onto the three-
phase AC utility line.
The 1336 REGEN Line Regeneration Package operates in two
basic modes —
Regenerative DC Bus Supply and Regenerative
Braking . These two operating modes give the 1336 REGEN Line
Regeneration Package the flexibility to handle a wide variety of
applications.
1336 REGEN Line Regeneration Package Components
The 1336 REGEN Line Regeneration Package consists of two
main pieces.
1. A Converter that transforms a three-phase AC input source into
a DC output source.
2. A Precharge Unit that limits inrush current and provides AC line
voltage phase and magnitude information to the converter.
In addition to these two components, a 1321 Line Reactor is
required. The line reactor used for Regenerative Bus Supply
applications is a custom design with a nominal impedance of 10%.
Operation in the Regenerative DC Bus Supply Mode may also
require the use of an additional power line filter, depending upon
the AC line source impedance. Operation in the Regenerative
Brake Mode requires the use of a line reactor with a nominal
impedance of 3%. Figure 2.1 and Figure 3.1 show the basic layout
differences between 1336 REGEN Regenerative DC Bus Supply
and 1336 REGEN Regenerative Brake applications.
