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.

Programming the Drive
for Network Communication
This section describes how to configure a VTAC 7 drive for use with an LonWorks
network. The sections that follow describe the VTAC 7 parameters related to
LonWorks network operation. For other drive parameter descriptions, refer to the
VTAC 7 User Manual.
6.1 Setting the Control Source (P.000)
Parameter Range: LOCL = Local keypad/display
rE = Terminal strip remote inputs
OP = Option port
SErL = Serial port (CS3000 or OIM)
Default Setting: LOCL
Parameter Type: Configurable
CHAPTER 6
Parameter P.000 (Control Source) selects the source of control information for the
drive (start, jog, direction, etc.). To start and stop the drive over the network,
parameter P.000 must be set to OP. This parameter can be written over the network
only when the drive is stopped.
After parameter P.000 is set to OP, the Remote LED on the keypad should turn on to
show the network is in control of the drive. Note that parameter P.000 does not
prevent the drive from communicating on the network; it only allows the drive to be
controlled and the reference to be supplied from the network.

6.2 Setting the Network Connection Type (P.061)
Parameter Range: 0 = Basic drive connection
1 = Full drive connection
Default Setting: 0
Parameter Type: Configurable
Refer also to paramete rs: N/A
Parameter P.061 (Network Connection Type) selects the type of network connection.
Setting P.061 = 1 provides full drive control from the network. Any drive data that has
been assigned a network register is transferred over the network. Parameter P.061
must be set to 1 to configure the drive over the network and have access to most
parameters, operating variables, and diagnostic information. The LonWorks module
will fault the drive if P.061 is not set to 1.
6.3 Setting the Commu nication Loss Response (P.062)
Parameter Range: 0 = IET fault
1 = Hold last reference
2 = Use terminal strip reference
Default Setting: 0
Parameter Type: Tunable
Refer also to paramete rs: P.000 Control Source
Parameter P.062 (Communication Loss Response) specifies how the drive responds
to a network communication loss when the Control Source (P.000) parameter is set to
OP (Option port).
If the option port is not in control of the drive, but is only monitoring drive operation,
then loss of network communications has no effect on drive operation. In all cases, the
LonWorks module, upon loss of communication with the network, will attempt to
re-establish the communication link.
T o eliminate extraneous fault conditions when a drive configured for network operation
is powered up, the drive will delay for approximately 20 seconds after power up before
annunciating a fault condition. A fault condition will be annunciated if network
communication is not established before the 20-second power-up timer expires, or if
network communication was established and then lost.
If the drive loses communication with the network, overspeed protection for the drive
will be in effect under all circumstances. you program overspeed protection in H.022.
When the motor goes above the overspeed limit, the drive faults and stops.
6-2
LonWorks Module for VTAC 7 Drives
P.062 Option Port: Communication Loss Response
If P.062 = 0
The drive will consider a loss of network communication to be a drive fault, resulting in
an IET-type stop sequence.
When P.062 is set to IET fault (0) and communication is lost:
(continued)
• The drive latches a fault condition and performs a coast stop.
• The network communication loss fault is generated (nCL is displayed).
• The front panel REMOTE LED blinks, indicating that the network is inactive.
When network communication is re-established, you must reset the fault before the
drive can be re-started. See the VTAC 7 User Manual for information on resetting
faults. (A fault reset does not clear the error log.)
If P.062 = 1
The drive continues to operate, using the last reference received from the network.
ATTENTION:In volts/hertz regulation, if P .000 (Control Source) is set to
OP (Option Port), and P .062 is set to 1 (hold last reference), and the drive

loses communication with the network, the drive will maintain the last
frequency command sent to it. Ensure that drive machinery , all drive-train
mechanisms, and application material are capable of safe operation at

The response to network communication loss is:
• The drive continues to operate, using the last reference received from the network
master.
• An entry is made into the drive’s error log for each active-to-inactive transition of
network communicat ion status .
• The front panel REMOTE LED blinks, indicating that the network is inactive.
If network communication is re-established, the drive will again follow the reference
and sequencing control inputs supplied by the network. Note that if P.054 = ON and
the start and stop inputs are on (1), the drive will start.
Note that in this configuration, it might not always be possible to stop the drive over
the network.
Programming the Drive for Network Communication
6-3
P.062 Option Port: Communication Loss Response
If P.062 = 2
The drive gets its speed/torque reference from the terminal strip analog input and its
stop input from the terminal strip stop input. All other inputs are held at the last values
received from the network.
This allows the network to continue controlling the drive reference with a direct-wired
analog output to input, and to stop the drive with a direct-wired digital output to input.
Note that if P.054 (Level Sense Start Enable) = OFF and the drive is stopped while in
this mode, it cannot be re-started until network communication is re-established or the
Control Source (P.000) is changed.
ATTENTION:If P.062 = 2 and P.054 (Level Sense Start Enab le) = ON

The response to network communication loss is:
• The drive continues to operate, using the analog input from the Regulator board
terminal strip.

Parameter Type: Tunable
Parameter P.028 (Speed Display Scaling) defines the scaling value applied to the
manual reference, the selected speed reference, and the output speed displays.
P.028 must be set to 100 for nvoDriveSpeed to show the correct percent of nominal

CHAPTER 7
Operating the Drive
Using a LonMark Profile
A LonMark profile defines the functional profile for a node communicating with other
nodes. The profile specifies which SNVTs (Standard Network Variable Types) and
SCPTs (Standard Configuration Property Types) are used, and provides a semantic
meaning about the information being communicated.
When a profile is implemented in a node, it’s called a LonMark object. One node can
have several objects implemented. The LonWorks module has two objects: a node
object and a drive object. The node object is used to control the other objects in a
node. See figure 7.1
Node Object
nviRequest
nv1
SNVT_obj_request
The drive object is based on a specific LonMark functional profile, as shown in figure
7.2.
Data exchange on a LonWorks network is handled with Standard Network Variable
Types (SNVTs), which represent different types of standard data (e.g., temperature,
pressure, voltage). The LonWorks module contains a fixed setup of SNVTs, and each
SNVT is mapped to a VTAC 7 drive parameter.
A network variable is any data item (such as temperature or a switch value) that a
particular device application program expects to receive from other devices on the
network (called an input network variable or NVI) or expects to make available to other
devices on the network (called an output network variable or NVO).
When a program writes into one of its output network variables, the new value of the
network variable is propagated across the network to all nodes with input network
variables connected to that output network variable.

Node Object Request
Definition: network input SNVT_obj_request nviObjRequest;
Explanation: Enables control commands and updates from the network. The
status of the node is reported in nvoObjStatus (see section 7.2).
Range:
• RQ_NORMAL is the normal request mode when node is in
normal run mode.
• RQ_DISABLED will stop the motor.
• RQ_ENABLE enables start of motor again after an
RQ_DISABLED request; otherwise, the same as
RQ_NORMAL.
• RQ_UPDATE_STATUS updates nvoObjStatus.
• RQ_CLEAR_STATUS clears nvoObjStatus.
• RQ_CLEAR_ALARM resets a fault in the drive, sets
drvSpeedStpt.value = 0 and drvSpeedStpt.state = 0. Uses

Drive Speed Setpoint
Definition: network input SNVT_switch nviDrvSpeedStpt.
Explanation: Provides a low-resolution speed setpoint. When
nviDrvSpeedStpt.State is set to zero, the drive stops based on
the stop mode defined by drive parameter P.025.
Important: Requested speed will not be greater than the value
defined by nciMaxSpeed or less than the value
defined by nciMinSpeed
Range:
State Percent Value Requested Speed
0 N/A Stopped
10% 0%
1 0.5% to 100.0% 0.5 to 100.0%
1 100.0% 100.0%
0xFF N/A Auto (Invalid)
Default: Auto (state = 0xFF). This value will be adapted at power up. This
variable may use the Receive Heartbeat function if the Receive
Heartbeat function is set up for use. The actual value of drive
speed also depends on nviDrvSpeedScale.
Scaling: See section 8.4.
Speed Setpoint Scaling
Definition: network input SNVT_lev_percent nviDrvSpeedScale;
Explanation: Provides scaling for nviDrvSpdStpt. For example, if
nviDrvSpeedStpt value is 100% and nviDrvSpeedScale value is
-150%, then actual speed setpoint value is -150% (meaning
reverse 1.5 times nominal speed). The requested speed will not
be greater than the value defined by nciMaxSpeed or less than
the value defined by nciMinSpeed.

LonWorks Module for VTAC 7 Drives
Conditions Required for Operation
This chapter describes the conditions required for performing some common actions
and how the combination of SNVTs and SCPTs affect the operation of the drive.
8.1 General Guidelines
• The LonWorks module and the drive must be installed and configured correctly.
Note the following VTAC 7 parameter settings:
• P.061 = 1. This enables the LonWorks module to have full access to all
parameters in the drive. The LonWorks module will fault the drive if this is not set
correctly.
• P.000 = OP. This enables the drive to accept frequency settings and/or start/stop
commands from the LonWorks module.
• P.028 = 100. This enables nvoDriveSpeed to show the correct percentage of
nominal speed. This is written by the LonWorks module at start up.
• NCIs (network config ur ati on prope rti es) are usuall y onl y written to the drive. NC I
values are read from the drive only at start up, when resetting faults, and when an
offline-to-online transition occurs. This is done to ensure consistency of parameters
values on both the LonWorks network and in the drive.
CHAPTER 8
• The tune/cfg bit in the VTAC 7 command word will be set automatically by network
variables that have a parameter in the drive that require the tune/cfg bit to be set.
This will al so cause all ot h e r t u ne /c fg parameters to be re a d by t he drive. This i s th e
equivalent of setting nviObjRequest to RQ_PROGRAM.
8.2 Starting the Drive
The drive will output a frequency when
• nviDrvSpeedStpt.value is greater than zero
• nviDrvSpeedStpt.state is not equal to zero
• nviDrvSpeed Scale is not equal to zero
• RQ_ENABLE has been requested more recently than RQ_DISABLED
• The node is online
all
of the following conditions are met:
Conditions Required for Operation
8-1
8.3 Stopping the Drive
The drive will stop using the stop mode selected in parameter P.025 if
following conditions are met:
• NviSpeedStpt.state is set to any value but 1
• The node is brought offline
• RQ_DISABLED is requested in nviObjRequest
8.4 Setting the Frequency
The actual value written to the LonWorks module =
(nviDrvSpeedStpt*0.5*nviDrvSpeedScale*0.005*nciNmlFreq*100) / (100*100)
Notes for above equation:
• Multiplied by 0.005 and 0.5 to scale the two LonWorks format values
• Nominal frequency is the base for scale and setpoint percent values
• Multiplied by 100 to fit LonWorks module format.
• Divided by (100*100) because the setting frequency is multiplied by two percent
values.
Refer to chapter 7 for information about nviSpeedStpt and nviSpeedScale.

150% 50% 1 1.5*0.50*Nomfreq
8.5 Writing Values to a VTAC 7 Register
To write a value to a VTAC 7 register:
Step 1. Change register in nciWriAddr.
Step 2. Change value in nciWriValue.
Changing the value in nciWriValue triggers the writing to a register in the LonWorks
module. Changing the address alone will not perform a write sequence.
To verify that the LonWorks module has accepted the value written to it, read it back
by setting nciRdAdr to the corresponding DP RAM feedback register. See Appendix B
for a list of registers.

8.6 Reading Values from VTAC 7 Registers
The address set in nciRdReg is polled and the result is written to nvoParam as often
as the value on the address changes or the work load on the host application and
nciMinOutTime allows.
NCIRdAdr Address NvoParam
004 Drop0 Register 4 Value read at address
8.7 Resetting Faults
If an error occurs, the drive faults. The fault can be reset from the LonWorks module
by first removing the cause of the fault, then setting nviObjRequest to
RQ_CLEAR_ALARM. All drive-related NCIs will be updated with the current drive
value.
8.8 Priority of nciMinOutTm and nciSendHrtBt
NciMinOutTm has priority over nciSendHrtBt. This means that heartbeats will not be
sent as often as specified in nciSendHrtBt if nciMinOutTm has a longer time set.

9.2 Error Handling
The LonWorks module handles errors in the following manner:
• If nciRcvHrtBt > 0, and heartbeats are not received within nciRcvHrtBt time, then
communication with the LonWorks network is considered down. This will result in a
net comm fault.
• The module responds as specified in Comm Loss Response.
• If the module does not get access to DP RAM in 250 ms, the comm_failure bit will
be set in the network output SNVT_obj_status nvoObjSatus. This will also result in a
net comm fault (force write in DP RAM without waiting on VTAC 7 drive).
