LonWorks Module for VTAC 7 Drives
CHAPTER 1
Introduction
This manual is intended for qualified electrical personnel responsible for installing,
programming, and maintaining AC drives and LonWorks networks. It provides
information about the LonWorks Communication Option Module (2LW3000) and
using it with VTAC 7 drives.
The LonWorks Communication Option module consists of a LonWorks module
mounted on an AnyBus board. It is mounted in the VTAC 7 drive and receives its
required power from the drive and the network.
LonWorks networks consist of intelligent control devices, called nodes, that are
connected by one or more communications media and that communicate with each
other using a common protocol. A LonWorks network can consist of up to 32.385
nodes divided into 255 subnets (127 nodes/subnet).
Nodes on the network can be thought of as objects that respond to various inputs and
produce desired outputs. Linking the inputs and outputs of network objects enables
the network to perform applications. No central control or master-slave architecture is
required.

understand this manual and other applicable manuals in their entirety
before proceeding. Failure to observe this precaution could result in
severe bodily injury or loss of life.
ATTENTION:The drive is at line voltage when connected to incoming
AC power. Disconnect, lock out, and tag all incoming power to the drive
before performing the following procedure. Failure to observe this
precaution could result in severe bodily injury or loss of life.
ATTENTION:DC bus capacitors retain hazardous voltages after input
power has been disconnected. After disconnecting input power, wait five
minutes for the DC bus capacitors to discharge and then check the
