1. SAFETY

1.1 Danger

1

The components of the power unit of the frequency converter are

live

when

Vacon NX_ is connected to mains potential.

Coming into contact with this

voltage is extremely dangerous and may cause death or severe injury.

2

The motor terminals U, V, W and the DC-link/brake resistor terminals are

live

when Vacon NX_ is connected to mains,

even if the motor is not running

.

3

After disconnecting the frequency converter from the mains, wait until the fan
stops and 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 Vacon
NX_ connections. Do not even open the cover before this time has expired.
Always ensure absence of voltage before starting any electrical work!

4

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 NX_ is disconnected from mains.

5

Before connecting the frequency converter to mains make sure that the
Vacon NX_ front and cable covers are closed.

6

If Vacon NX_ is disconnected from mains while running the motor, it
remains live if the motor is energized by the process. In this case the motor
functions as a generator feeding energy to the frequency converter.

1.2 Warnings

1

The Vacon NX_ frequency converter is meant for fixed installations only.

2

Do not perform any measurements when the frequency converter is con­nected to the mains.

3

The earth leakage current of Vacon NX_ frequency converters exceeds

3.5mA AC. According to standard EN61800-5-1, a reinforced protective
ground connection must be ensured. See chapter 1.4.

4

If the frequency converter is used as a part of a machine, the machine
manufacturer is responsible for providing the machine with a disconnecting
device (EN 60204-1).

5

Only spare parts delivered by Vacon can be used.

6

After the power-up, power brake or fault reset the motor will start immedi-

ately if the start signal is active, unless the pulse control for Start/Stop logic

has been selected. Futhermore, the I/O functionalities (including start
inputs) may change if parameters, applications or software are changed.
Disconnect, therefore, the motor if and unexpected start can cause danger.

7

Prior to measurements on the motor or the motor cable, disconnect the
motor cable from the frequency converter.

1.3 Cautions

1

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

2

Do not touch the components on the circuit boards. Static voltage discharge
may damage the components.

3

If a fault protection relay is used , it must be of at least type B, preferably B+

( according to EN 50178) , with a trip level of 300 mA. This is for fire
protection, not for touch protection in grounded systems.

1.4 Earthing and earth fault protection

The Vacon NX_ frequency converter must always be earthed with an earthing conductor connected to the

earthing terminal

.

The earth leakage current of Vacon NX_ exceeds 3.5mA AC. According to EN61800-5-1, one or more of the
following measures shall be applied, unless the touch current can be shown to be less than 3.5 mA AC or
10 mA DC:

A fixed connection and

a. The protective earthing conductor shall have a cross-sectional area of at least 10 mm

2

Cu or 16

mm

2

Al,

or

b. an automatic disconnection of the supply in case of loss of continuity of the protective earthing conductor.

See chapter 6.

or

c. provision of an additional terminal for a second protective earthing conductor of the same cross-

sectional area as the original protective earthing conductor,

Cross-sectional area of phase conductors

Minimum cross-sectional area of the cor­responding protective earthing conductor

[mm2]

S ≤ 16

S ≤ 35

35 <

S

S/2

The values above are valid only if the protective earthing conductor is made of the same metal as the phase
conductors. If this is not so, the cross-sectional area of the protective earthing conductor shall be determined
in a manner which produces a conductance equivalent to that which results from the application of this table.

Table 1. Protective earthing conductor cross-section

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

2

if mechanical protection is provided or

- 4mm

2

if mechanical protection is not provided. For cord-connected equipment, provisions

shall be made so that the protective earthing conductor in the cord shall, in the case of
failure of the strain-relief mechanism, be the last conductor to be interrupted.

The earth fault protection inside the frequency converter protects only the converter 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 frequency converter, fault current protective switches
may not function properly.

2. EU DIRECTIVE

2.1 CE marking

The CE marking on the product guarantees the free movement of the product within the EEA (European
Economic Area).

Vacon NX_ frequency converters carry the CE label as a proof of compliance with the Low Voltage Directive
(LVD) and the Electro Magnetic Compatibility (EMC). The company SGS FIMKO has acted as the Competent
Body.

2.2 EMC directive

2.2.1

General

The EMC Directive provides that the electrical apparatus must not excessively disturb the environment it is
used in, and, on the other hand, it shall have an adequate level of immunity toward other disturbances from
the same environment.

The compliance of Vacon NX_ frequency converters with the EMC directive is verified with Technical Con­struction Files (TCF) checked and approved by SGS FIMKO, which is a Competent Body. The Technical
Construction Files are used to authenticate the comformity of Vacon frequency converters with the Direc­tive because such a large-sized product family is impossible to be tested in a laboratory environment and
because the combinations of installation vary greatly.

2.2.2

Technical criteria

Our basic idea was to develop a range of frequency converters offering the best possible usability and cost­efficiency. EMC compliance was a major consideration from the outset of the design.

Vacon NX_ frequency converters are marketed throughout the world, a fact which makes the EMC require­ments of customers different. As far as the immunity is concerned, all Vacon NX_ frequency converters are
designed to fulfil even the strictest requirements, while as regards the emission level, the customer may
want to upgrade Vacon's already high ability to filter electro-magnetic disturbances.

2.2.3

Vacon frequency converter EMC classification

Vacon NX_ frequency converters are divided into five classes according to the level of electromagnetic
disturbances emitted, the requirements of a power system network and the installation environment (see
chapter 2.2.3.1). The EMC class of each product is defined in the type designation code.

Vacon EMC class C1 (NX_5, FR4 to FR6, Protection class IP54):
Frequency converters of this class comply with the requirements of category C1 of the product standard
EN 61800-3 (2004). Category C1 ensures the best EMC characteristics and it includes converters the rated
voltage of which is less than 1000V and which are intended for use in the 1st environment. NOTE: If the
protection class of the frequency converter is IP21 the requirements of class C1 are fulfilled only as far as
the conducted emissions are concerned.

Vacon EMC class C2 (NX_5, FR4 to FR9 and NX_2, FR4 to FR9):
Frequency converters of this class comply with the requirements of category C2 of the product standard
EN 61800-3 (2004). Category C2 includes converters in fixed installations and the rated voltage of which is
less than 1000V. The class C2 frequency converters can be used both in the 1st and the 2nd environment.

12 • vacon EU DIRECTIVE

Tel. [phone] • Fax [phone]

2

Vacon EMC class L (Protection classes IP21 and IP54: NX_5 FR10 and greater, NX_6 FR6 and greater):
Frequency converters of this class comply with the requirements of category C3 of the product standard
EN 61800-3 (2004). Category C3 includes converters the rated voltage of which is less than 1000V and
which are intended for use in the second environment only.

Vacon EMC class T:
Frequency converters of this class fulfil the product standard EN 61800-3 (2004) if intended to be used in IT
systems. In IT systems, the networks are isolated from earth, or connected to earth through high
impedance to achieve a low leakage current. NOTE: if converters are used with other supplies, no EMC
requirements are complied with.

Vacon EMC class N:
The drives of this class do not provide EMC emission protection. These kinds of drives are mounted in
enclosures. NOTE: An external EMC filter is usually required to fulfil the EMC emission requirements.

All Vacon NX_ frequency converters fulfil all EMC immunity requirements (standard EN 61800-3

(2004).

Note: For changing the EMC protection class of your Vacon NX_ frequency converter from class H or L to
class T, please refer to the instructions given in Chapter 6.1.3.

2.2.3.1 Environment definitions in product standard EN 61800-3 (2004)

First environment: Environment that includes domestic premises. It also includes establishments directly
connected without intermediate transformers to a low-voltage power supply network which supplies
buildings used for domestic purposes.
NOTE: houses, apartments, commercial premises or offices in a residential building are examples of first
environment locations.

Second environment: Environment that includes all establishments other than those directly connected to
a low-voltage power supply network which supplies buildings used for domestic purposes.
NOTE: industrial areas, technical areas of any building fed from a dedicated transformer are examples of
second environment locations.

2.2.4

3.2 Storage

If the frequency converter is to be kept in store before use make sure that the ambient conditions are
acceptable:

Storing temperature –40…+70

°C

Relative humidity <95%, no condensation

If the converter is to be stored during longer periods power should be connected to the converter once a
year and kept on for at least 2 hours. If the storage time exceeds 12 months the electrolytic DC capacitors
need to be charged with caution. Therefore, such a long storage time is not recommended. If longer
storage time is, however, necessary, follow the instructions in chapter 3.3.1 to recharge the capacitors.

3.3 Maintenance

In normal conditions, Vacon NX_ frequency converters are maintenance-free. However, regular
maintenance is recommended to ensure a trouble-free operation and a long lifetime of the drive. We
recommend to follow the table below for maintenance intervals.

Maintenance interval Maintenance action

Whenever necessary

•

Clean heatsink

Regularly

•

Check tightening torques of terminals

12 months (if unit stored)

• Recharge capacitors (see chapter 3.3.1)

6-24 months

(depending on environment)

• Check input and output terminals and control

I/O terminals.

• Clean cooling tunnel.

• Check operation of cooling fan, check for cor-

rosion on terminals, busbars and other surfaces

•

Check door filters in case of cabinet installation

5-7 years

• Change cooling fans:

- main fan

- internal IP54 fan

-

cabinet cooling fan/filter

5-10 years

•

Change DC bus capacitors

Table 3-1. Maintenance intervals

3.3.1

Capacitor recharge

After a longer storage time the capacitors need to be recharged in order to avoid capacitor damage.
Possible high leakage current through the capacitors must be limited. The best way to achieve this is to
use a DC-power supply with adjustable current limit.

1) Set the current limit to 300…800mA according to the size of the drive.

2) Then connect the DC-power supply to the B+/B- terminals (DC+ to B+, DC- to B-) of the DC-link or

directly to the capacitor terminals. NX converters with no B+/B- terminals (FR8/FR9) can be powered
connecting the DC-supply between two input phases (L1 and L2).

3) In drives FR8 to FR12: To ensure full recharge of capacitors, remove the fuses of the cooling fan. Ask

factory for further instructions if necessary.

4) Then set the DC-voltage to the nominal DC-voltage level of the unit (1.35*Un AC) and supply the

converter for at least 1h.

If DC-voltage is not available and the unit has been stored much longer than 12 months deenergized,
consult the factory before connecting power.

3.4 Warranty

Only manufacturing defects are covered by the warranty. The manufacturer assumes no responsibility for
damages caused during or resulting from transport, receipt of the delivery, installation, commissioning or
use.

The manufacturer shall in no event and under no circumstances be held responsible for damages and
failures resulting from misuse, wrong installation, unacceptable ambient temperature, dust, corrosive
substances or operation outside the rated specifications.

Neither can the manufacturer be held responsible for consequential damages.

The Manufacturer's time of warranty is 18 months from the delivery or 12 months from the commissioning
whichever expires first (Vacon Warranty Terms).

The local distributor may grant a warranty time different from the above. This warranty time shall be
specified in the distributor's sales and warranty terms. Vacon assumes no responsibility for any other
warranties than that granted by Vacon itself.

In all matters concerning the warranty, please contact first your distributor.

4. TECHNICAL DATA

4.1 Introduction

Figure 4-1 presents the block diagram of the Vacon NX_ frequency converter. The frequency converter
mechanically consists of two units, the Power Unit and the Control Unit. Pictures of the mechanical
assemblage on pages 57 to 65.

The three-phase AC-choke (1) at the mains end together with the DC-link capacitor (2) form an LC-filter,
which, again, together with the diode bridge produce the DC-voltage supply to the IGBT Inverter Bridge (3)
block. The AC-choke also functions as a filter against High Frequency disturbances from the mains as well
as against those caused by the frequency converter to the mains. It, in addition, enhances the waveform of
the input current to the frequency converter. The entire power drawn by the frequency converter from the
mains is active power.
The IGBT Inverter Bridge produces a symmetrical, 3-phase PWM-modulated AC-voltage to the motor.

The Motor and Application Control Block is based on microprocessor software. The microprocessor
controls the motor basing on the information it receives through measurements, parameter settings,
control I/O and control keypad. The motor and application control block controls the motor control ASIC
which, in turn, calculates the IGBT positions. Gate drivers amplify these signals for driving the IGBT
inverter bridge.

The control keypad constitutes a link between the user and the frequency converter. The control keypad is
used for parameter setting, reading status data and giving control commands. It is detachable and can be
operated externally and connected via a cable to the frequency converter. Instead of the control keypad,
also a PC can be used to control the frequency converter if connected through a similar cable.

You can have your frequency converter equipped with a control I/O board which is either isolated (OPTA8)
or not isolated (OPTA1) from the ground.

The basic control interface and the parameters (the Basic Application) are easy to use. If a more versatile
interface or parameters are required, a more suitable application can be chosen from the "All in One+"
Application Package. See the "All in One+" Application Manual for more information on the different
applications.

A brake resistor is available as internal option for frames FR4 to FR6 of voltage classes NX_2 and NX_5. In
all other frames of voltage classes NX_2 and NX_5, as well as in all frames of all other voltage classes, the
brake resistor is available as option and installed externally.

Optional I/O expander boards that increase the number of inputs and outputs to be used are also available.
For closer information, contact the Manufacturer or your local distributor (see back cover).

5. INSTALLATION

5.1 Mounting

The frequency converter can be mounted in either vertical or horizontal position on the wall or on the back
plane of a cubicle. However, if the drive is mounted in a horizontal position,

it is not protected against

vertically falling drops of water.

Enough space shall be reserved around the frequency converter in order to ensure a sufficient cooling, see
Figure 5-10, Table 5-10 and Table 5-11. Also see to that the mounting plane is relatively even.

The frequency converter shall be fixed with four screws (or bolts, depending on the unit size). The
dimensions of installation are presented in Figure 5-10 and Table 5-10.

Lift units bigger than FR7 out of the package using a jib crane. Ask the factory or your local distributor for
information on how to lift the unit safely.

Below you will find the dimensions of both wall-mounted as well as flange-mounted Vacon NX_ frequency
converters. The dimensions of the opening needed in flange mounting are given in Table 5-3 and Table 5-5.

The sizes FR10 to FR12 are floorstanding units. The enclosures are equipped with fixing holes. For dimen­sions see below.

See also chapter 5.2 Cooling.
