DANGER
!
Rotating shafts and electrical equipment can
be hazardous. Therefore, it is strongly
recommended that all electrical work
conform to National Electrical Code (NEC)
and all local regulations. Installation, start-
up and maintenance should be performed
only by qualified personnel.
Motor control equipment and electronic controls are
connected to hazardous line voltages. When servicing
drives and electronic controls, there will be exposed
components at or above line potential. Extreme care
should be taken to protect against shock. Stand on an
insulating pad and make it a habit to use only one hand
when checking components. Always work with another
person in case of an emergency. Disconnect power
whenever possible to check controls or to perform
maintenance. Be sure equipment is properly grounded.
Wear safety glasses whenever working on electric control
or rotating equipment.
WARNING
!
Warnings Against Unintended
Start
1. While the drive is connected to the AC line, the motor
can be brought to a stop by means of external switch
closures, serial bus commands or references. If personal
safety considerations make it necessary to ensure that
no unintended start occurs, these stops are not sufficient.
2. During programming of parameters, the motor may start.
Be certain that no one is in the area of the motor or
driven equipment when changing parameters.
3. A motor that has been stopped may start unexpectedly
if faults occur in the electronics of the drive, or if an
overload, a fault in the supply AC line or a fault in the
motor connection or other fault clears.
4. If the “Local/Hand” key is activated, the motor can only
be brought to a stop by means of the “Stop/Off” key or
an external safety interlock.
CAUTION
!
Electronic components of LonWorks option card
are sensitive to electrostatic discharge (ESD).
ESD can reduce performance or destroy
sensitive electronic components. Follow proper
ESD procedures during installation or servicing
to prevent damage.
Touching electrical parts may be fatal, even after equipment has
been disconnected from AC line. To be sure that capacitors have
fully discharged, wait 14 minutes for 2 8 V and 46 V units and
3 minutes for 6 V units over 25 HP after power has been
removed before touching any internal component.

LON
Concept
LonWorks
Overview
Applications
LonWorks is both an existing standard and
hardware developed by Echelon Corporation.
Echelon's stated goal is to establish a com-
modity solution to the presently daunting
problems of designing and building control
networks.
The result is LonMark Interoperability which
makes it possible for independent network
devices to operate together over a LonWorks
network. The LonMark program was
developed to address interoperability issues.
As a result, the LonMark Interoperability
Association Task Groups were developed.
The task groups determine that each device
on the network has an object definition,
create standards and models to be used by
The LonWorks communications structure is
similar to that of a local area network (LAN)
in that messages are continually exchanged
between a number of processors. A
LonWorks system is a determined local
operating network (LON). LON technology
offers a means for integrating various
distributed systems that perform sensing,
monitoring, control, and other automated
functions. A LON allows these intelligent
devices to communicate with one another
through an assortment of communications
media using a standard protocol.
LON technology supports distributed, peer-
to-peer communications. That is, individual
network devices can communicate directly
with one another without need for a central
control system. A LON device is designed to
move sense and control messages which are
typically very short and which contain
commands and status information that trigger
actions. LON performance is viewed in terms
of transactions completed per second and
response time. Control systems do not need
vast amounts of data, but they do demand
that the messages they send and receive are
absolutely correct. The critical factor in LON
technology is the assurance of correct signal
transmission and verification.
An important LonWorks benefit is the
network’s ability to communicate across
different types of transmission media. The
NEURON chip is the heart of the LonWorks
system. The NEURON chip's communication
port allows for the use of transceivers for other
media (such as coax and fiber optic) to meet
special needs.
LonWorks control devices are called nodes.
Physically, each node consists of a NEURON
chip and a transceiver. With proper design,
the nodes become building blocks that can
be applied to control a variety of tasks, such
as lighting or ventilating, integrating a variety
of communications media.
The tasks which the nodes perform are
determined by how they have been connected
and configured. Because hardware design,
software design, and network design may be
independent in a LonWorks-based system, a
node’s function can be programmed to
accommodate the networks in which it will be
used.
particular applications and create a common
platform for presenting data. A standard
network variable type (SNVT) facilitates
interoperability by providing a well defined
interface for communication between devices
made by different manufacturers. The TR1
Series VFD supports the LonMark functional
profile for variable speed motor drives. It also
supports node object and controller standard
object definitions.
Customers are currently using LonWorks for
process control, building automation, motor
control, elevator operation, life safety systems,
power and HVAC distribution and similar
intelligent building applications.

TR1 Series
VFD
LonWorks
Option Card
The Trane TR1 Series VFD LonWorks option
card is comprised of a control card with a
NEURON chip and a memory card. When
installed into the TR1 Series variable frequency
drive, the unit enables the drive to
communicate with other devices on the LON.
The TR1 Series drive is designed to provide
precision control of standard induction electrical
motors for HVAC applications. The drive
receives three reference signals along with
start/stop and reset commands from the
network. The drive also receives a 16-bit control
word that provides full operational control of
the drive. (See Network Drive Control Input for
additional details.)
In response, the drive provides 16 output
network variables containing important drive
and motor data. (See Drive Feedback to
Network.) Output to the network includes drive
status, current, voltage, motor and inverter
thermal status, and alarms and warnings.
The TR1 Series VFD LonWorks free topology
option card, 176F1515, supports four
transmission media, which also operates on a
link power network (used for Comm 5). A router
is required to interface to a LonWorks network
when not supported by the option card.
Network
Management
Depending on the level of a given application,
a LonWorks network may or may not require
the use of a network management node. A
network management node performs
management functions, such as:
• Find unconfigured nodes and download
their network addresses.
• Stop, start, and reset node applications.
• Access node communication statistics.
• Configure routers and bridges.
• Download new applications programs.
• Extract the topology of a running
network.
TR1 Series
VFD
Applications
Common applications for the Trane TR1 Series
VFD include the following.
• The TR1 is factory mounted or field
applied under control of discrete I/O from
another controller. It is possible to
monitor the TR1 using Tracer Summit's
generic LonTalk device (GLD) object.
• The TR1 is field applied using closed loop
PID control. It is possible to enable/
disable, change setpoints, and monitor
the control through Tracer Summit using
the GLD object.
• The TR1 can be controlled digitally when
used in conjunction with Trane's AH540
and MP580 Comm 5 (LON) controllers.
• The TR1 could be operated in an open
loop control method and, under certain
circumstances, an override or contact
closure can send the drive to a preset
value.
Within a Trane BAS system, the Tracer Summit
building controller unit (BCU) and/or Rover
Service tool act as the network managers.

System
Performance
• The average temperature of the wire
must not exceed 131° F. Individual
segments of wire may be as hot as
185° F.
System
Specifications
Free topology system specifications and
transmission specifications are described
below. Both specifications should be met to
ensure proper operation.
The transmission specification depends on such
factors as resistance, mutual capacitance and
the velocity of propagation.
The system designer may choose from a variety
of cables, depending on cost, availability, and
desired performance. Performance may vary
with cable type. Contact Echelon for cable types
and the characterization of system performance.
Note
The following specifications are for
one network segment. Multiple
segments may be combined using
repeaters to increase the number of
nodes and distance.

Wiring
Installation
TR1 Series variable frequency
drive contains dangerous voltages
when connected to line power.
After disconnecting from line, wait
at least 14 minutes before
touching any electrical com-
ponents.
Only a competent electrician
should carry out electrical
installation. Improper installation
of motor or TR1 drive can cause
equipment failure, serious injury
or death. Follow this manual,
National Electrical Code and local
safety codes.
WARNING

Network
Initialization
of LonWorks
Option Card
LonMark
Drive Profile
A LonMark external interface file (.XIF
extension) provides the host processor with
device information. With this, it is possible
to design a LonWorks network without the
drive being physically present. The resource
file is available for downloading from the
Trane website at www.trane.cso.tr1vfd.com/
index.html , or contact Trane GCC Product
Support.
The drive may also be added to the network
upon initialization.
The LonWorks option card contains a NEURON
chip with a unique address. After hardware
installation, initialize the LonWorks option card
by using a Tracer Summit BCU or Rover
running in active mode. Addressing nodes on
the LonWorks network is performed at
installation time by an installation tool or
network management tool. Addressing
requires the retrieval of a node’s NEURON ID.
The NEURON ID is a 48 bit number that identifies
every manufactured NEURON chip. There are
several methods by which the network
software will initialize the drive automatically.
The network can recognize the drive without
action beyond proper installation. The card is
then ready to be programmed for network
operation. The TR1 LonWorks option supports
three additional methods of addressing a node:
1. Service Pin - There are two
momentary-contact service switches that
send the NEURON ID over the network. If the
network software prompts the action, press
either service pin (SW1 or SW3) to transmit
the NEURON ID over the network. The service
pin locations are shown in the illustration in
Terminator and Service Switch Locations in
this manual.
2. Query and Wink - The LonWorks option
card is shipped with a domain of “0” and
subnet of “1.” Upon receiving the wink
command, the on-board green status LED
flashes so that the installer can locate the node.
The chip sends out its Neuron ID over the
network in response to the query command.
3. NEURON ID Label - The TR1 LonWorks
option card has a NEURON ID label that displays
the NEURON ID as a 12 digit hexadecimal
number. The installer can manually enter the
NEURON ID during installation.
The TR1 LonWorks network interface consists
only of SNVTs. The SNVTs support the
LonMark Controller Profile along with TR1
configuration, control and monitoring
capabilities. Any combination of SNVTs can be
used to operate the TR1.
Also supported is the functional profile for variable
speed drives from the LonMark Interoperability
Association at www.lonmark.org/products/
fprofile.htm#industrial . This profile defines a
set of network variables (SNVTs) and
configuration properties (SCPTs).
