Honeywell • 2 Safety
1. Safety
This manual contains clearly marked cautions and warnings which are intended for your personal safety and to avoid any unintentional damage to the product or connected appliances.
PLEASE READ THE INFORMATION INCLUDED IN CAUTIONS AND WARNINGS CAREFULLY.
The cautions and warnings are marked as follows:
1.1 Danger
= DANGER! Dangerous voltage
= WARNING or CAUTION
= Caution! Hot surface
Table 1. Warning signs
The components of the power unit of drive are live when the AC drive is connected to mains potential. Coming into contact with this voltage is extremely dan-
gerous and may cause death or severe injury.
The motor terminals U, V, W and the brake resistor terminals are live when
drive is connected to mains, even if the motor is not running.
After disconnecting the AC drive from the mains, wait until the indicators on the
keypad go out (if no keypad is attached see the indicators on the cover). Wait 5
more minutes before doing any work on the connections of drive. Do not open the
cover before this time has expired. After expiration of this time, use a measuring
equipment to absolutely ensure that no
voltage is present.
Always ensure absence
of voltage before starting any electrical work!
The control I/O-terminals are isolated from the mains potential. However, the relay
outputs and other I/O-terminals may have a dangerous control voltage present
even when drive is disconnected from mains.
Before connecting the AC drive to mains make sure that the front and cable covers
of drive are closed.
During a ramp stop (see the Application Manual), the motor is still generating voltage to the drive. Therefore, do not touch the components of the AC drive before the
motor has completely stopped. Wait until the indicators on the keypad go out (if no
keypad is attached see the indicators on the cover). Wait additional 5 minutes before
starting any work on the drive.

1.2 Warnings
1.3 Earthing and earth fault protection
The drive must always be earthed with an earthing conductor connected to the earthing terminal marked with .
The earth leakage current of drive exceeds 3.5mA AC. According to EN61800-5-1, one or more
of the following conditions for the associated protective circuit shall be satisfied:
a) The protective conductor shall have a cross-sectional area of at least 10 mm
2
Cu or
16 mm
2
Al, through its total run.
b) Where the protective conductor has a cross-sectional area of less than 10 mm
2
Cu or
16 mm
2
Al, a second protective conductor of at least the same cross-sectional area
shall be provided up to a point where the protective conductor has a cross-sectional
area not less than 10 mm
2
Cu or 16 mm2 Al.
c) Automatic disconnection of the supply in case of loss of continuity of the protective con-
ductor.
Drive is meant for fixed installations only.
Do not perform any measurements when the AC drive is connected to the mains.
The earth leakage current of drives exceeds 3.5mA AC. According to standard
EN61800-5-1, a reinforced protective ground connection must be ensured. See
chapter 1.3.
If the AC drive is used as a part of a machine, the machine manufacturer is respon-
sible for providing the machine with a supply disconnecting device (EN 60204-1).
Only spare parts delivered by Honeywell can be used.
At power-up, power brake or fault reset the motor will start immediately if the start
signal is active, unless the pulse control for Start/Stop logic has been selected.
Furthermore, the I/O functionalities (including start inputs) may change if parameters,
applications or software are changed.Disconnect, therefore, the motor if an unexpected start can cause danger.
The motor starts automatically after automatic fault reset if the auto restart function
is activated. See the Application Manual for more detailed information.
Prior to measurements on the motor or the motor cable, disconnect the motor
cable from the AC drive.
Do not touch the components on the circuit boards. Static voltage discharge may
damage the components.
Check that the EMC level of the AC drive corresponds to the requirements of your
supply network.
CAUTION!
Honeywell • 4 Safety
The cross-sectional area of every protective earthing conductor which does not form part of the
supply cable or cable enclosure shall, in any case, be not less than:
- 2.5 mm
2
if mechanical protection is provided or
-4 mm
2
if mechanical protection is not provided.
The earth fault protection inside the AC drive protects only the drive itself against earth faults
in the motor or the motor cable. It is not intended for personal safety.
Due to the high capacitive currents present in the AC drive, fault current protective switches
may not function properly.
Do not perform any voltage withstand tests on any part of drive. There is a
certain procedure according to which the tests shall be performed. Ignoring this
procedure may result in damaged product.
LonWorks - general info Honeywell • 5
2. LonWorks - general info
Drive frequency converters can be connected to the LonWorks ® network using a fieldbus
board. The converter can then be controlled, monitored and programmed from the Host system.
LONWORKS technology has been developed by Echelon Corporation. LONWORKS network
is used in applications like industry and building automation, controlling household electronics,
medical instrumentation and many others. The target 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 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. Honeywell option board uses only Standard Network Variable Types for the data types.
All network variables are either input (data is coming from the network to the device) or output
(data is sent to the network by 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.
If you need further information related to LonWorks, please contact Fieldbus@Honeywell.com.

3. LonWorks technical data
3.1 General
3.2 Physical media and wiring
LONWORKS networks can be implemented on many different physical media. Drive OPT-C4
option board is equipped with an FT-X1 transceiver supporting the Free Topology transformer
coupled network, which allows the network wire to be connected as bus, star, loop or combination of these. This media reaches a communication speed of 78kBits/s. The FT-X1 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.
Figure 1. Doubly terminated bus topology
The doubly terminated bus topology is recommended to be used. However, also singly termiated, star or loop topologies can be used with OPT-C4 option board.
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 for possible cable types and cable lengths
for FTT-10. Even if unshielded cable types are possible to be used with this type of transceiver,
it is still highly recommended to use only shielded cables with frequency converters. Attention should be paid to proper grounding of the shield to ensure bus operation. Grounding of
the shield should be done at both ends of the cable.

3.3 Profiles
LonMark Functional Profiles describe in detail the application layer interface, including the network variables, configuration properties, and default and power-up behaviors required on LonMark devices for specific, commonly used control functions.
3.3.1 Variable speed profile
Leading manufacturers of drive technology have jointly defined the LonMark profile. The profile
specifies how the drives are to be parameterized and how the setpoints and actual values are
to be transmitted. This enables drives from different vendors to be exchanged. The profile contains necessary specifications for speed control and positioning. It specifies the basic drive
functions while leaving sufficient freedom for application-specific expansions and further developments.

4.3 Prepare for use through LonWorks
4
Strip about 15 mm of the fieldbus cable (see specification on page 6) and cut off
the grey cable shield. Remember to do this for both bus cables (except for the
last device).
Leave no more than 10 mm of the cable outside the terminal block and strip the
cables at about 5 mm to fit in the terminals. See picture below.
Also strip the cable now at such a distance from the terminal that you can fix it to
the frame with the grounding clamp. Strip the cable at a maximum length of 15
mm. Do not strip the aluminum cable shield!
5
Then connect the cable to its appropriate terminals on LonWorks Option Board
terminal block.

Using the cable clamp included in the delivery of the drive, ground the shield of
the LonWorks cable to the frame of the AC drive.
7
If drive is the last device on the bus, the bus termination must be set. To
assure a proper data transmission, termination of the network segments is
required. Depending on the type of network, either one or two terminations are
necessary. Free topology network segment requires only one termination
whereas a doubly terminated bus topology requires two.
The jumper X5 on the Honeywell LonWorks board must be set accordingly.
• Use 94-ohm termination resistance when only one termination is needed
• 47-ohm termination resistance for two terminations

Unless already done for the other control cables,
cut free the opening on the AC drive cover for
the fieldbus cable (protection class IP21).
NOTE: Cut the opening on the same side you
have installed the board in!
9
Remount the AC drive cover and run the cable
as shown in picture.
NOTE: When planning the cable runs, remember
to keep the distance between the fieldbus cable
and the motor cable at a minimum of 30 cm.
10
The bus termination must be set for the first and the last device of the fieldbus
line. See picture below. See also step 7 on page 13. We recommend that the first
device on the bus and, thus, terminated was the Master device.

6.3 Input Network Variables
nviRequest
This input network variable provides the mechanism to request a particular mode for the Node
object or the Variable Speed Motor Drive object within a node. Supported requests are
RQ_NORMAL, RQ_UPDATE_STATUS, RQ_CLEAR_STATUS, RQ_REPORT_MASK,
RQ_DISABLED, RQ_ENABLE and RQ_CLEAR_ALARM.
nviDrvSpeedStpt
This input network variable provides control and a low resolution speed setpoint.
nviDrvSpeedScale
This input network variable provides scaling for nviDrvSpeedStpt. Negative values indicate a
motor direction in reverse. For example, if the nviDrvSpeedStpt value is 50% and nviDrvSpeedScale -150%, then the actual speed setpoint is -75%, or 0.75 times the nominal speed in reverse direction. The valid range is -163,840% to 163,830. The value 0x7FFF (+163,835%) will
be handled as an invalid value. Default value is determined by nciDrvSpeedScale. This value
will be adopted at power-up and in case of not receiving an update within the specified Receive
Heartbeat time.

This output network variable provides the drive resettable energy consumption counter. The
maximum value for used SNVT is 65535 kWh. On the frequency converter 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 drive operating keypad.
nvoActFault
This output network variable provides the drive active fault code. If the value is 0 the frequency
converter has no fault. See the fault code list in drive User's Manual for fault identification.
nvoProcessOut1..8
These output network variables are sent directly from the application (see more detailed explanation in chapter 6.5 Process data) The valid range is 0 to 65535 (-163,840 to 163,835)
nvoDigitalOut1..8
These output network variables are sent directly from the application (see more detailed explanation in chapter 6.5 Process data).

6.5 Network configuration variables
nciMaxSpeed
This configuration property is used to define the maximum speed of a motor. The value is entered as a percentage of nominal speed in RPM, as defined by the Nominal Speed (nciNmlSpeed) configuration value. The value of the maximum speed must be validated against the
value of the minimum speed as follows:
-163.840 < minimum speed < maximum speed < 163.830
nciMinSpeed
This configuration property is used to define the minimum speed of the motor. The value is entered as a percentage of nominal speed in RPM, as defined by the Nominal Speed (nciNmlSpeed) configuration value. The value of the minimum speed must be validated against the
value of the maximum speed as follows:
-163.840 < minimum speed < maximum speed < 163.830
nciRcvHrtBt
This configuration property is used to control the maximum time that elapses after the last update of the network variables nviDrvSpeedStpt or nviDrvSpeedScale before the VSD object
starts to use the default values.
nciSndHrtBt
This configuration property defines the maximum period that expires before the network variables nvoDrvSpeed, nvoDrvCurnt and nvoDrvPwr are automatically updated.
nciMinOutTime
This configuration property defines the minimum period of automatic network variable tansmission.

nciNmlSpeed
This configuration property is used to provide the nominal speed of the motor in RPM. This value is necessary to determine the minimum and maximum speeds for the motor, based on the
configuration properties nciMinSpeed, nciMaxSpeed (entered as a percentage of nominal
speed).
nciNmlFreq
This configuration property is used to provide the nominal frequency for the motor.
nciRampUpTm
Defines the acceleration time for drive. The valid range is 0.0 to 6,553.4 sec (0.1 sec).
nciRampDownTm
Defines the deceleration time for drive. The valid range is 0.0 to 6,553.4 sec (0.1 sec).
nciDrvSpeedScale
This configuration property is used as the default value for nviDrvSpeedScale. This value will
be adopted at power-up and in case no input variable within the specified Receive Heartbeat
time is received.
Fault tracing Honeywell • 25
7. Fault tracing
When an unusual operating condition is detected by the AC drive control diagnostics, the drive
initiates a notification visible, for example, on the keypad. The keypad will show the ordinal
number of the fault, the fault code and a short fault description.
The fault can be reset with the Reset button on the control keypad or via the I/O terminal. The
faults are stored in the Fault history menu which can be browsed. The different fault codes you
will find in the table below. This fault table presents only the faults related to the fieldbus in use.
The LonWorks option board status LEDs are described in more detail in Chapter 4.1.2
NOTE: When contacting distributor or factory because of a fault condition, always write down
all texts and codes on the keypad display and send a description of the problem together with
the Drive Info File to fieldbus@Honeywell.com.
7.1 Typical fault conditions
If you need to contact Honeywell service in problems related to LonWorks, please send a description of the problem together with the Drive Info File to fieldbus@Honeywell.com.
Fault condition Possible cause Remedy
