Index
The SECURE DISABLE function and secure input on Unidrive SP and the SAFE
TORQUE OFF function of the Digitax ST meet the requirements of EN954-1 category 3
for the prevention of unexpected starting of the drive. They may be used in a safetyrelated application. The system designer is responsible for ensuring that the
complete system is safe and designed correctly according to the relevant safety
standards.
Glossary Of
Terms
The SECURE DISABLE / SAFE TORQUE OFF function is only available as standard on
the Unidrive SP / Digitax ST, The Affinity and Commander SK drives do not have a
secure disable feature.
Quick Reference
The STOP and SECURE DISABLE / SAFE TORQUE OFF functions of the drive do not
isolate dangerous voltages from the output of the drive or from any external option unit.
The supply must be disconnected by an approved electrical isolation device before
gaining access to the electrical connections.
Diagnostics
Close attention is required to the electrical installation and the system design to avoid
hazards, either in normal operation or in the event of equipment malfunction. System
design, installation, commissioning / start up and maintenance must be carried out by
personnel who have the necessary training and experience. They must read this safety
information and this User Guide carefully.
Functional
Blocks
The drive uses high voltages and currents, carries a high level of stored electrical
energy, and is used to control equipment which can cause injury.
Module
Parameters
System design and safety of personnel
Getting Started
The voltages used in the drive can cause severe electrical shock and/or burns, and
could be lethal. Extreme care is necessary at all times when working with or adjacent to
the drive.
1.3
Mechanical
Installation
A Caution contains information, which is necessary for avoiding a risk of damage to the
product or other equipment.
Careful consideration must be given to the functions of the drive which might result in a
hazard, either through their intended behaviour or through incorrect operation due to a
fault. In any application where a malfunction of the drive or its control system could lead
to or allow damage, loss or injury, a risk analysis must be carried out, and where
necessary, further measures taken to reduce the risk - for example, an over-speed
protection device in case of failure of the speed control, or a fail-safe mechanical brake
in case of loss of motor braking.
1.4
Environmental limits
Instructions in the Unidrive SP User Guide, Affinity User Guide and Commander SK
Getting Started Guide, Commander SK Technical Data Guide, Digitax ST Getting
Started Guide and Digitax ST Technical Data Guide regarding transport, storage,
installation and use of the drive must be complied with, including the specified
environmental limits. Drives must not be subjected to excessive physical force.
1.5
Compliance with regulations
The installer is responsible for complying with all relevant regulations, such as national
wiring regulations, accident prevention regulations and electromagnetic compatibility
(EMC) regulations. Particular attention must be given to the cross-sectional areas of
conductors, the selection of fuses or other protection, and protective ground
connections.
The Unidrive SP User Guide, Affinity User Guide, Commander SK Technical Data
Guide and Digitax ST Technical Data Guide contain instructions for achieving
compliance with specific EMC standards.
Within the European Union, all machinery in which this product is used must comply
with all relevant safety and EMC directives applicable to the installation.
1.6
Motor
Ensure the motor is installed in accordance with the manufacturer’s recommendations.
Ensure the motor shaft is not exposed.
Standard squirrel cage induction motors are designed for single speed operation. If it is
intended to use the capability of the drive to run a motor at speeds above its designed
maximum, it is strongly recommended that the manufacturer is consulted first.
Low speeds may cause the motor to overheat because the cooling fan becomes less
effective. The motor should be installed with a protection thermistor. If necessary, an
electric forced vent fan should be used.
The values of the motor parameters set in the drive affect the protection of the motor.
The default values in the drive should not be relied upon.
It is essential that the correct value is entered in the motor rated current parameter,
Pr 5.07 (or Pr 0.46 in Unidrive SP, Affinity and Digitax ST, or Pr 0.06 in Commander
SK). This affects the thermal protection of the motor.
1.7
Adjusting parameters
Some parameters have a profound effect on the operation of the drive. They must not
be altered without careful consideration of the impact on the controlled system.
Measures must be taken to prevent unwanted changes due to error or tampering
especially if a remote user can access the drive parameters.

General safety considerations for remote operation
SM-LON enables the possibility of remotely controlling a machine from a distance. It is
vital that when connecting to a machine remotely, adequate safety procedures are
implemented to prevent damage to the machine or injury to personnel.
It is the responsibility of the machine builder to ensure that such a system is safe
and complies with current legislation.
Introduction
Any connection to a “live” system has the possibility of altering the state of the machine,
adequate procedures must be implemented to cover this situation.

Introduction
2.1
SM-LON features
The SM-LON is a Solutions Module that can be used on the following products to
provide connectivity to a LonWorks® network:
•
Unidrive SP
•
Affinity
•
Commander SK
•
Digitax ST
The following list gives an overview of the functionality available within SM-LON.
NOTE
2.1.1
•
Single 3-way 5mm (0.2in) pitch screw terminal pluggable / removable
connector
•
Supplementary grounding tag
•
Support for “Node Object” functional block
•
Support for “Variable Speed Motor Drive” (VSD) functional block profile
•
“Service pin” operation controlled by parameter
•
“Wink” LED
•
“Service” LED
•
Free topology operation. (78kBit/s, twisted pair, TP/FT-10)
•
Automatic setting of reference parameters for network control
•
Internal termination resistors selectable by switches
Although the LonWorks® network specification provides for supplying the DC supply to
the device over the network data wires (“Link power”, TP/LP-10), SM-LON does not
require this DC supply and will not be affected if this supply is connected.
Unidrive SP: Backup/auxiliary supply
Unidrive SP and Affinity can be connected to a +24Volt backup power supply using the
control terminals. This keeps the control electronics and Solutions Module(s) powered
up, allowing the SM-LON network to continue communicating when the main AC supply
is removed.
2.1.2
What Is LonWorks®?
The “LON” in “LonWorks®” is an acronym of Local Operating Network. Its major
application is in building management and HVAC networks.
LonWorks® is intended primarily for distributed applications where there is no master or
PLC controlling the network data flow.
Each device on the LonWorks network is linked to other devices using network
variables, these network variables can be either input or output variables, the output
network variable of one device is linked to the input network variable of another device.
Network variable values are updated at pre-set intervals or whenever polled by a
device. The network links are configured using a network configuration tool, this
configuration tool may then be removed after the network has been configured.

Product conformance
SM-LON is a “LonMark® Certified Product” and has been fully tested to conform to the
interoperability guidelines from LonMark International.
2.4
Conventions used in this guide
The configuration of the host drive is by means of menus and parameters. A menu is a
logical collection of parameters that have similar functionality. The SM-LON module
also has parameters but these are mainly for indication only and the configuration is
done by the network configuration tool software application.
In the case of a Solutions Module, the parameters will appear in menu 15, 16 or 17
depending on which slot the option module is installed in. The menu is determined by
the number before the decimal point.
The method used to determine the menu or parameter is as follows:
•
•
10
Pr xx.00
- signifies any menu and parameter number 00.
Pr MM.xx
- where MM signifies the menu allocated to the solutions module
(this could be 15, 16 or 17 on the Unidrive SP and Digitax ST, 15 or 16 on the
Affinity drive but will always be 15 on the Commander SK) and xx signifies the
parameter number.

SM-LON module information
SM-LON provides a single 3-way screw connection to a LonWorks® network. In
addition to the 3-way screw connector a grounding tag is supplied for supplementary
bonding. The 3-way screw terminals are double insulated to provide electrical isolation
from live components in the drive.
SM-LON also provides 2 diagnostic LEDs for status and information purposes. The
function of each LED is described in Table 8.1 on page 56.
The network termination resistors are selected by means of two DIP switches, each
switch connects a 56 Ω resistor across the network data lines.

SM-LON uses a free topology network architecture and supports the TP/FT-10 network
topology with a data rate of 78kBit/second. The use of free topology means that the
network may consist of bus, ring, or star (wye) connected devices. It is recommended
that bus connections are used because of the greater network segment length allowed.
It is recommended that the network cable used should be one listed in Table 4.2. If the
cable used is not one of the recommended cables, the network reliability may be
compromised and technical support may be limited.

Untwisted wires or cables containing flat or parallel untwisted conductors must not be
used on a LonWorks® twisted pair channel. The use of these wires/cables may result in
improper network operation and could result in damage to the nodes connected.
Each segment of the network must be terminated correctly for reliable operation; for a
bus connected segment, each end of the segment must be terminated with a 56 Ω
resistor; for a free topology segment, the segment needs to be terminated with two 56 Ω
resistors, these may be installed at any convenient terminal.

Index
The SM-LON module uses two AC coupled resistors for network termination. The value
of each resistor is approximately 56 Ω, selectable by means of the DIP switch. To select
a termination resistor the switch should be closed (down), to remove the termination the
switch should be opened (up).

The SM-LON module is equipped with two resistors (56 Ω each) both of which are
individually selectable using the selector switch, this allows the SM-LON module to be
the only network device with termination resistors installed.
Introduction
In this type of architecture, the termination resistors may be installed to any single
device or any two devices in the segment but there must be a total of two resistors (56 Ω
each) installed on each segment.
Safety
Information
A free topology system has virtually no restrictions on the topology of architecture used.
The main types of topology are bus. star (wye), tree and ring; all of these (in any

LonWorks® network overview
To provide interoperability between different manufacturers, the LonWorks® network
uses pre-defined functional blocks. Each of these profiles contain a number of input and
output network variables and configuration properties. SM-LON supports the Node
Object and Variable Speed Motor Drive (VSD) functional block, both of these functional
blocks are explained in Chapter 7 Functional Blocks on page 36.
There are two types of network variables, these are Standard Network Variable Type
(SNVT) and User-defined Network Variable Type (UNVT). The network variables are
used to transfer the data between devices, the outputs of a device are connected to the
inputs of another device.
The configuration properties are generally set once during commissioning / start up and
stored in the device’s non-volatile memory. There are also two types of configuration
properties, Standard Configuration Property Type (SCPT) and User-defined
Configuration Property Type (UCPT).
A LonWorks® network consists of one or more domains, each domain can
accommodate up to 255 subnets and each subnet can accommodate up to 127
devices.
5.1.1
Addressing
Each device on a LonWorks® network has two different addresses. The first address is
a 48 bit physical address that is fixed in the neuron® IC of the LonWorks® device, this
is known as the neuron® ID. The second address consists of the node ID (0 to 127),
subnet ID (0 to 255) and the domain ID (0 to 248-1).
5.1.2
Node ID
Every device on a subnet must have its own unique node identifier. This node identifier
can be any whole number in the range 0-127.
5.1.3
Subnets
A subnet is a group of devices connected together and addressed using the same
domain and subnet identifiers. The subnet identifier can be any whole number in the
range 0-255.
5.1.4
Domains
A domain is a group of devices connected together and addressed using the same
domain identifier, either directly or through a repeater, that can communicate with each
other. A device can only communicate with another device on the same domain. The
domain identifier can be any whole number in the range 0 to 248-1.

NOTE
Functional
Blocks
This parameter is used (in conjunction with the received heartbeat time configuration
variable - nciRcvHrtBt) to cause a trip condition if the network is lost. The value of the

Setting up a LonWorks® network
This section is intended to provide a generic guide for setting up the SM-LON module
on a simple LonWorks® network. Due to the many different types and manufacturers of
LonWorks® devices, it is not possible to provide detailed information for all devices, the
LonPoint™ devices used in this section are manufactured by the Echelon®
Corporation.
NOTE
Although the Echelon® Corporation is mentioned in this document, this does not
represent an endorsement of any particular device or device manufacturer, other devices
may be used.
When configuring a LonWorks® network, each device must be configured separately
using a network configuration tool such as the LonMaker™Integration Tool (other
configuration tools may also be used).
Before configuring the network devices, it is important to check the network cabling and
termination are correct. If the cabling or installation is not correct then the stability and
reliability of the network may be compromised.
For further information on network cabling, see section 4.3 Network cabling on page 13.
The network may also not operate correctly if a network segment is incorrectly
terminated. For further information on network termination, see section 4.5 Network
termination on page 13.

neuron ID of the device and allows the LonMaker™network integration tool to
commission the device. The SM-LON module does not use a button, but a drive
parameter (Pr MM.36) is provided for this purpose. When this parameter is changed
from ‘OFF’ (0) to ‘ON’ (1), SM-LON will transmit the service message and the “Service

Parameters
5.4.2
Getting Started
The speed scaling (nviDrvSpeedScale) and maximum speed (nciMaxSpeed) network
variables should both be set to 100.000 (%). The motor speed is now controlled by
nviDrvSpeedStPt. For more information on using this network variable refer to Table
7.6 on page 44.
Electrical
Installation
To run a motor, there are some network variables to be set, first the motor rated speed
should be set in nciNmlSpeed (RPM) and the motor rated frequency should be set in
nciNmlFreq (Hz), these should be set as specified on the motor nameplate.
Mechanical
Installation
After the SM-LON module has been configured on the network, the drive must be
configured to use the appropriate references. This can be achieved in one of two ways,
the first way is to set the parameter Pr MM.34 to ON and save the parameters by setting
Pr xx.00 to 1000 and resetting the drive. The second way is to use the network variable
nviSetupDrvPars and set the value of its State attribute to 1, this will set all relevant
parameters and save the new values.

Functional Blocks
7.1
What is a functional block?
A functional block represents a collection of network variables and configuration
properties on a device that perform a related function. For example, a digital input
device with four input switches contains one functional block for each switch.
A functional block is similar in appearance and usage to function blocks used in PLC
programming. Each functional block contains a series of variables used as network data
links (Network Variables) and another series of variables used to configure the device
(Configuration Properties).
7.2
Network variables
Network variables are objects within the functional block and provide the mechanism for
devices to send and receive data over the network.
There are two types of network variables, standard network variable (SNVT) and userdefined (UNVT).
Each functional block contains a series of network variables, these variables can be
either input or output variables. Input variables names are prefixed “nvi” (Network
Variable Input) and output variables names are prefixed “nvo” (Network Variable
Output).
7.3
Configuration properties
Configuration properties are user-configurable values which define the behaviour of a
device. They are stored in the non-volatile memory of the device and normally only set
once during device commissioning.
There are two types of configuration properties, standard configuration properties
(SCPT) and user-defined configuration properties (UCPT).
A functional block may contain one or more of these configuration properties.
7.4
Supported functional blocks
SM-LON supports two functional blocks, these being the Node Object and Variable
Speed Motor Drive (VSD).

7.4.2
Node Object Input Network Variable
Table 7.1 nviRequest
nviRequest
SNVT Type: SNVT_obj_request
Default: N/A
Mandatory
Syntax: Object_ID,Object_Request
This input network variable provides the mechanism to request an operation or a mode for a
functional block within a device. The request consists of an object identifier (Object_ID) followed
by an object request code (Object_Request).
The Object_ID is the index number for a functional block on the device. The Node Object
functional block index is always zero, the remaining functional blocks are numbered
sequentially, starting at one.
The available values for the Object_Request code are as follows:
RQ_NORMAL
(Object_Request=0)
This code will return the device to the normal operating state.
If the device was disabled then this code will clear the disabled state.
If this request is made to the node object, all of the functional blocks
(including the node object) will be returned to their normal operating
states.
RQ_DISABLED
(Object_Request=1)
When this code is applied to the node object, it will be applied to the
VSD functional block automatically and the node object output
variables will not be propagated to the network (the nvoStatus and
nvoAlarm2 variables will not be disabled).
When this code is applied to the VSD functional profile, the behaviour
will be as follows:
If the drive is not currently running, the drive will be inhibited.
If the drive is running, the drive will be stopped using the VSD profile
parameter settings, when the drive has stopped it will then be
inhibited. This will be done using the drive control word (Pr 6.42). This
drive state will be forced and it will prevent the drive from being run
over the network.
The VSD output variables will also be prevented from being
propagated to the network (it will still be possible to poll them).
RQ_UPDATE_STATUS This code will request the status of the specified functional block to be
sent to the nvoStatus output network variable.
(Object_Request=2)
If the node object functional block was specified then the status
returned would be the inclusive-OR of both the node object status and
the VSD functional block status. (See nvoStatus network variable).
38
RQ_REPORT_MASK
(Object_Request=5)
This code will result in a status mask value to be sent to the
nvoStatus output network variable.
The status mask value shows all of the supported status bits for the
specified device. (See nvoStatus network variable).
If the node object functional block was specified then the status mask
value returned would be the inclusive-OR of both the node object
status mask value and the VSD functional block status mask value.
RQ_ENABLE
(Object_Request=7)
When this command is applied to the node object only the node object
network variables will be propagated over the network.
When this command is applied to the VSD functional block, the
behaviour will be as follows:
The LonWorks network variables which run the drive will take effect;
SM-LON will stop forcing the drive inhibit if the previous state was
RQ_DISABLED. The VSD output network variables that are
connected to other devices will be propagated over the network.
RQ_CLEAR_ALARM
(Object_Request=10)
This command can be used to clear any drive trip (except hardware
fault trips), the network variable nvoAlarm2 is also cleared if possible.
This command is supported by the VSD functional block profile only, if
this command is sent to the node object, the invalid_request bit will be
set in the nvoStatus network variable.

This output network variable is used to return a 25 field data string which contains the Object_ID
in the first data field with the remaining data fields used to indicate the status of the specified
object. The significance of each bit in the data string is shown below.
If the RQ_REPORT_MASK command is used in the nviRequest node object network variable
then nvoStatus will return a status mask value which indicates the supported status bits of the
specified functional block.
If the node object is specified in the RQ_REPORT_MASK command then nvoStatus will return
a status mask value which would be the inclusive-OR of both the node object status mask value
and the VSD functional block status mask value.

These bytes are ASCII coded string characters and will contain the trip
code as defined in the relevant drive user guide or, in the case of an
alarm condition, the alarm message.
If no alarm or trip condition is present, the values read back in the first
seven bytes will be 78,111,32,84,114,105,112 (the remaining bytes will
all be set to zero values); this decodes as the message “No Trip”.
If a trip condition is present then the values returned will be
84,114,105,112,32 (“Trip “) followed by the drive trip code.
For example, if an output current overload trip was present (It.AC - trip
code 20), the following values will be returned:
84,114,105,112,32,50,48; this decodes as “Trip 20”.
If an alarm condition is present, an appropriate message will be
returned.
Drive trip messages will take priority over any alarm condition currently
present.

Functional
Blocks
For values of Byte3 less than 128. (positive parameter values from 0 to 231-1).
value = Byte0 + (Byte1 * 256) + (Byte2 * 2562) + (Byte3 * 2563).

For example, to write the value “123456789” to the drive parameter specified in nviInDest2,
21 * 1 = 21
Byte1 = 205
205 * 256 = 52480

will give an indication of the number of network variable updates per second. This
includes received messages from other devices and transmitted messages from SMLON. These messages will generally be network variable updates.
If the SM-LON module cannot be detected on the network by the network configuration
tool or other devices on the same domain, then the value in this parameter can be used
to assist in diagnosing the cause of the problem. Table 8.2 SM-LON operating status
