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:

= DANGER! Dangerous voltage

= WARNING or CAUTION

= Caution! Hot surface

Table 1. Warning signs

1.1 Danger

The components of the power unit of Vacon 100 are live when the AC drive is
connected to mains potential. Coming into contact with this voltage is extremely
dangerous and may cause death or severe injury.

The motor terminals U, V, W and the brake resistor terminals are live when
Vacon 100 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 Vacon100. Do not
open the cover before this time has expired. After expiration of this time, use a
measuring equipment to absolutely ensure that no

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 Vacon 100 is disconnected from mains.

Before connecting the AC drive to mains make sure that the front and cable cov­ers of Vacon 100 are closed.

voltage is present.

Always

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.

vacon • 4 Safety

1.2 Warnings

Vacon 100 AC 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 Vacon 100 AC 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
responsible for providing the machine with a supply disconnecting device (EN
60204-1).

Only spare parts delivered by Vacon 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
Futhermore, 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.

Start/Stop logic has been selected

.

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.

1.3 Earthing and earth fault protection

CAUTION!

The Vacon 100 AC drive must always be earthed with an earthing conductor connected to the
earthing terminal marked with .

The earth leakage current of Vacon 100 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 mm2 Cu or 16

mm2 Al, through its total run.

b) Where the protective conductor has a cross-sectional area of less than 10 mm2 Cu or

16 mm2 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 mm2 Cu or 16 mm2 Al.

c) Automatic disconnection of the supply in case of loss of continuity of the protective

conductor.

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:

-2.5mm

-4mm
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.

if mechanical protection is provided or

2

if mechanical protection is not provided.

Do not perform any voltage withstand tests on any part of Vacon 100. There is a
certain procedure according to which the tests shall be performed. Ignoring this
procedure may result in damaged product.

2. LONWORKS - GENERAL INFO

Vacon 100 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. Vacon 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.

3.2 Physical media and wiring

LONWORKS networks can be implemented on many different physical media. Vacon 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.

Termination Termin ation

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.

Strip about 15 mm of the fieldbus cable (see specification on page 9) 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.

If Vacon 100 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 Vacon LonWorks board must be set accordingly.

• Use 94-ohm termination resistance when only one termination is needed

• 47-ohm termination resistance for two terminations

nvoDrvRunHours

This output network variable provides the drive resettable operation time counter for the mo­tor in running hours. The maximum value for used SNVT is 65535 h. 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 Vacon 100 HVAC
operating keypad.

nvoDrvStatus

This output network variable provides the drive status.

Bit Description

Value = 0 Value = 1

0 Not Ready Ready
1 FC stopped Running
2 Clockwise Counterclockwise
3 No fault Fault active
4 No warning Warning active
5 Reference not Actual value Reference = Actual value

nvoDrvEnrgy

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 Vacon 100 HVAC 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 Vacon 100 HVAC User's Manual for fault iden­tification.

Table 14. 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 Vacon 100 HVAC. The valid range is 0.0 to 6,553.4 sec (0.1 sec).

nciRampDownTm

Defines the deceleration time for Vacon 100 HVAC. 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.

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 [e-mail].
