1. INTRODUCTION
1.1 General
SV9000 drives can be connected to a LONWORKS®network using the SV9NCLCN option board kit. The
drive can then be controlled, monitored and programmed from the LONWORKS® network.
The LonWorks® option board can also extend the used I/O:
x 4 digital inputs (standard signals)
x 4 digital outputs (standard signals)
x thermistor input (can be directly connected to the motor thermistors for overtemperature trip)
x Encoder input
The interface board must be installed in the external option enclosure outside the drive.
1.2 About this manual
The purpose of this manual is to provide you with the information how to install and set up your SV9000
LONWORKS®Option Board for communication over a LONWORKS®network. For more specific
information on installation and operation of the SV9000 refer to the SV9000 Drive User’s Manual and
SV9000 Fieldbus Application User’s Manual.
This manual assumes that you are familiar with the SV9000 drive and are using the LONWORKS®Option
Board with a SV9000 drive using the application for fieldbus support. It is also assumed that you are
familiar with LONWORKS®and its installation procedures and tools.
1.3 Safety Precautions
Before starting the installation, carefully read all warnings and safety instructions in the SV9000 Drive
User’s Manual.
Internal components and circuit boards (except the isolated I/O terminals) are at utility
potential when the SV9000 is connected to the utility. This voltage is extremely dangerous and
may cause death or severe injury if you come in contact with it.
The control I/O terminals are isolated from the utility potential, but the I/Os (if jumper X9 is in
OFF-position) may have a dangerous voltage connected even if the power is off on SV9000.

2. LonWorks®
2.1 Overview
Echelon Corporation has developed LonWorks® technology. LONWORKS®network is used for
applications in industry and building automation, controlling household electronics, medical
instrumentation and many others. The goal of the LONWORKS®network is to provide a common
vendor independent communication network for intelligent devices.
In a LONWORKS®network, no central control or master-slave architecture is needed. Nodes on a
network communicate with each other using the LonTalk®protocol. Interoperable nodes use
Standard Network Variable Types (SNVT) for communicating over the network. The definition of
an SNVT includes units, a range, and an increment. SV9000 LONWORKS®uses only Standard
Network Variable Types as data types.
All network variables are either input (data comes from the network to the device) or output (data
is sent to the network from the device) network variables. When network variables on different
nodes on the network have been bound together by an installation tool, passing of data is
automatic between the right nodes. Only the same type of network variables can be bound
together, so it is very important to have compatible interfaces.
2.2 Physical media and wiring
LONWORKS®networks can be implemented on many different physical media. SV9000 SV9NCLW
option board is equipped with an FTT-10A transceiver supporting the Free Topology transformer
coupled network, which allows the network wire to be connected as bus, star, loop or mixed.
Communication speed with this media is 78kBits/s. The FTT-10A transceiver is compatible with
Echelon’s LPT-10 Link Power Transceiver, and these transceivers can communicate with each
other on a single twisted pair cable.

Up to 64 FTT-10 transceiver nodes are allowed per network segment, the individual segments can be
connected together by a router. See table 3-1 for recommended cable types and cable lengths for FTT-
10. Even though unshielded cable types are recommended to be used with this type of transceiver, it is
still highly recommended to use only shielded cables with drives. Attention should be paid to proper
grounding of the shield to ensure bus operation, grounding of the shield should be done on both ends of
the cable.

Table 2-1 FTT-10 wiring
2.3 Bus termination
The FTT-10 network segment requires termination for proper data transmission performance. A total
termination impedance of approximately 52.3:is required.
In a free topology segment, only one termination is required and may be placed anywhere on the free
topology segment. In a doubly terminated bus topology, two terminations are required, one at each end
of the bus.
The SV9000 SV9NCLW option board is equipped with termination resistors, which can be selected by
jumper X6. If the jumper is in the ‘ST’ position single termination is selected and if it is in ‘DT’ double
termination is selected. If termination is not done at this node the jumper should be removed or
positioned so that it is connected to one pin only.

2.4 Service button and LED
Every LONWORKS®device has a service button, which is needed during network installation. Pressing
the button causes the node to send its unique ID number to the network. Because the SV9000
LONWORKS®Option Board is located under drive’s cover in normal use, the service button operation can
be done by changing the value of a service button parameter from 0 to 1 or vice versa on the SV9000
operating panel. The location of the service button parameter depends on the used SV9000 application.
Each LONWORKS®device should also have a service LED on it. The LED shows the operating state of
the device by blinking. On SV9000 the operating state can be seen on the operating panel as actual
value 22. See table 3-2 for coding of the states.
Node State State Code Service LED
Applicationless and Unconfigured 3 On
Unconfigured 2 Flashing
Configured 4 Off

3. INSTALLATION
Before starting the installation, carefully read the safety instructions in the " SV9000 Drive User's
Manual" chapter “SAFETY”. Check that you have recieved all the LONWORKS® kit parts: Repeater board
on mounting board, power cable (black terminal), data cable (blue terminal) and LONWORKS®board in
the separate option enclosure.
Repeater board with mounting board can be installed in the existing option board place inside the drive
(see figure 4-1).
ARemove the control panel and the jumper X4 from the control board. Install the jumper that
you removed from terminal X4 of the control board, on terminal X9 of the Fieldbus board in
the ON or OFF position.
BConnect the power cable to terminal X5 of the control board and the data cable to terminal
X14. The power cable can also be connected to terminal X6 if the power cable from the
power board is connected to terminal X5.
CPut the data and power cables through the holes in the mounting board.
DInstall the mounting board on the standoffs by the larger holes and push it into the right
position in the slots on the standoffs . Check that the mounting board is stable and secure it
with a screw to the lower left standoff. If you have difficulties to place the board, slightly bend
regulator A4 and capacitor C59 of the control board.
EConnect the power cable to terminal X1 of the Repeater board and the data cable to
terminal X2.
FConnect the cable coming out of the option enclosure to terminal X3 of the repeater board.
Find the closest grounding terminal on the drive and strip the cable so that you can
ground the shield under the grounding terminal.
GAfter this install the control panel back in its place.
H If you use a 5 V encoder input, install the jumper in terminal X7 (see figure 5-1) of the
LONWORKS®board

Table 6-1 Network input variables
*) depends on the selected parameter
nviFreqRef
When fieldbus control in SV9000 has been selected, it follows this network input variable as the
frequency reference. This value is the percentage of the frequency area between the set minimum
and maximum frequency.
nviPIconAct
This network input variable is used only with a PI-control application with fieldbus support. This
variable is the actual value from the process to be controlled by the drive’s PI-control.
nviStartSto
When fieldbus control in SV9000 has been selected, this network input variable controls the
starting and stopping of the drive. When the value is set different from 0, the SV9000 will start
using the selected start function and when the value is set to 0 the SV9000 will stop using the
selected stop function.
nviDirectio
When fieldbus control in SV9000 has been selected, this network input variable controls the
direction of rotation. Value 0 is forward and any other value sets the rotation to reverse.
nviRstFault
Setting a non-0 value to this variable will reset the active fault in SV9000. This variable will
automatically go back to value 0 after the fault has been reset.
nviMinFreq
Defines the minimum frequency for SV9000. If the value is changed via the network it is not saved in the
drive’s non-volatile memory, unless bit 0 in nciEeprSave has been set to 1.

nviMaxFreq
Defines the maximum frequency for SV9000. If the value is changed via the network it is not saved in
the drive’s non-volatile memory, unless bit 1 in nciEeprSave has been set to 1.
nviAccelTim
Defines the acceleration time for SV9000. If the value is changed via the network it is not saved in the
drive’s non-volatile memory, unless bit 2 in nciEeprSave has been set to 1.
nviDecelTim
Defines the deceleration time for SV9000. If the value is changed via the network it is not saved in the
drive’s non-volatile memory, unless bit 3 in nciEeprSave has been set to 1.
nviClrEnrgy
Giving a non-zero value to this variable clears the SV9000’s resettable energy consumption counter.
nviParIn
This network input variable can be used to write a value to any of the SV9000’s parameters. Network
configuration variable nciParInPt defines the parameter that will be written. If the value is changed via
the network it is not saved in the drive’s non-volatile memory, unless bit 4 in nciEeprSave has been set
to 1.

**)depends on drive nominal current
nvoActFreq
This network output variable’s value is the SV9000’s output frequency in percent of the frequency
area between the set minimum and maximum frequency. Two configuration variables control
when this value is propagated to the network.
nvoMtrCurnt
This network output variable’s value is the SV9000’s output current. Configuration variable
nciCurrDlta controls when this value is propagated to the network.
nvoMtrPwr
This network output variable’s value is the SV9000’s output power in percent of its nominal power.
Configuration variable nciPwrDelta controls when this value is propagated to the network.
nvoDrvEnrgy
This network output variable’s value is the SV9000’s resettable energy consumption counter. The
maximum value for used SNVT is 65535 kWh, on the drive the value can go much higher. If the
counter exceeds the SNVT’s maximum value, the network variable stays at its maximum. In such
cases the real value can be seen on the SV9000’s control panel. Configuration variable

nciMaxRcvTm
The LONWORKS®Option Board will initiate bus-time-out activities when the max. receive time has
expired without receiving an input network variable. Action taken by the drive depends on the setting of
the fieldbus fault response parameter. The communication watchdog function is disabled when this
network configuration variable is set to 0.
nciActSndTm
This network configuration variable sets the maximum time between transmissions of nvoActFreq, so it
can be used as a heartbeat to monitor the operation of the network connection. The maximum send time
function is disabled when this network configuration variable is set to 0.
nciActDelta
This network configuration variable sets how much nvoActFreq’s value has to change before it is
transmitted. When this network configuration variable is set to 0, nvoActFreq is not transmitted, unless
nciActSndTm is set.
nciCurrDlta
This network configuration variable sets how much nvoMtrCurnt’s value has to change before it is
transmitted. When this network configuration variable is set to 0, nvoMtrCurnt will not be transmitted.
nciPwrDelta
This network configuration variable sets how much nvoMtrPwr’s value has to change before it is
transmitted. When this network configuration variable is set to 0, nvoMtrPwr will not be transmitted.
nciEnrgyDlt
This network configuration variable sets how much nvoDrvEnrgy’s value has to change before it is
transmitted. When this network configuration variable is set to 0, nvoDrvEnrgy will not be transmitted.
nciParDelta
This network configuration variable sets how much nvoParOut’s value has to change before it is
transmitted. When this network configuration variable is set to 0, nvoParOut will not be transmitted.
nciParInPt
This network configuration variable sets the address of the parameter written by nviParIn. The address
is formed from the group and the parameter number, defined by the application in the drive. The group
number is multiplied by 100 and the parameter number is added to it. For example the parameter 3 in
group 4 has the address 403.
nciParOutPt
This network configuration variable sets the address of the parameter or variable, which is read in
nviParOut. The address is formed from the group and parameter number, defined by the application in
the drive. The group number is multiplied by 100 and the parameter number is added to it. Group
number 0 is used for actual value variables.
nciEeprSave
This network configuration variable is a bit mask, which defines if some of the network input variables
are written to SV9000’s non-volatile memory, when changed from network. If a bit is set to 1, the
corresponding variable will be saved.
