The components of the power unit of the inverter are live when the Vacon
NX is connected to DC supply. Coming into contact with this voltage is
extremely dangerous and may cause death or severe injury. The
control unit is isolated from mains potential.

The supply and motor terminals are live when the Vacon NX is connected
to DC supply, even if the motor is not running.

The control I/O-terminals are isolated from the mains potential.
However, the relay outputs and other I/O-terminals may have dangerous
control voltage present even when the Vacon NX is disconnected from the
DC supply.
.

The inverter has a large capacitive leakage current.

If the inverter is used as a part of a machine, the machine manufacturer
is responsible for providing the machine with a main switch (EN 60204-1).

Only spare parts delivered by Vacon can be used.

The Vacon NX inverter is meant for fixed installations only.

Do not perform any measurements when the inverter is connected to the
DC supply.

After having disconnected the inverter from the DC supply, wait until the
fan stops and the indicators on the keypad go out (if no keypad is
attached see the indicator through the keypad base). Wait 5 more
minutes before doing any work on Vacon NX connections. Do not even
open the cover before this time has expired.

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.

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

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

Before connecting the inverter to DC supply, make sure that the Vacon
NX front and cable covers are closed.

1.3 Earthing and earth fault protection

The Vacon NX inverter must always be earthed with an earthing conductor connected to the earthing
terminal.

The earth fault protection inside the inverter only protects the inverter against earth faults in the
motor or the motor cable.

Due to the high capacitive currents present in the inverter, fault current protective switches may not
function properly. If fault current protective switches are used, they need to be tested with earth
fault currents present during possible fault situations.

Before starting the motor, check that the motor is mounted properly and
ensure that the machine connected to the motor allows the motor to be
started.

Set the maximum motor speed (frequency) according to the motor and
the machine connected to it.

Before reversing the motor, make sure that this can be done safely.

Make sure that no power correction capacitors are connected to the
motor cable.

Make sure that the motor terminals are not connected to mains
potential.

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). It also guarantees that the product complies with applicable directives
(for example, the EMC directive and other possible so-called new method directives).

Vacon NX inverters carry the CE label as a proof of compliance with the Low Voltage Directive (LVD)
and the Electro Magnetic Compatibility (EMC) directive. SGS FIMKO has acted as the Competent
Body.

2.2 EMC directive

2.2.1 Introduction

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 inverters with the EMC directive is verified with Technical Construction
Files (TCF) and checked and approved by SGS FIMKO, which is a Competent Body. The Technical
Construction Files are used to authenticate the conformity of Vacon inverters with the Directive
because it is impossible to test such a large product family 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 inverters offering the best possible usability and cost­efficiency. EMC compliance was a major consideration from the outset of the design.

Vacon NX inverters are marketed throughout the world, a fact which makes the EMC requirements
of customers different. As far as immunity is concerned, all Vacon NX inverters are designed to fulfil
even the strictest requirements.

2.2.3 Vacon inverter EMC classification

Factory delivered Vacon NX inverters are Class T equipment, which fulfil all EMC immunity
requirements (standards EN 50082-1, 50082-2 and EN 61800-3).

Class T:
Class T equipment have a small earth leakage current and can be used with floating DC input. If they
are used with other supplies, no EMC requirements are complied with.

Warning: This product is of the restricted sales distribution class according to IEC 61800-3. In
residential areas, this product may cause radio interference in which case the user may be required
to take adequate measures.

4. TECHNICAL DATA

4.1 Introduction

The figure below presents the block diagram of the Vacon NX inverter. The inverter mechanically
consists of two units, the Power Unit and the Control Unit.

The Power Unit contains an inverter bridge which consists of IGBT switches and produces a
symmetrical, 3-phase PWM-modulated AC voltage to the motor. To protect the DC-link capacitors,
the Power Unit also contains a charging circuit for controlled DC-link charge. Use the B+ and DC­terminals in order to bypass the charging circuit.

The Motor and Application Control Block is based on microprocessor software. The microprocessor
controls the motor based 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 inverter. The control keypad is used
for parameter setting, reading status data and giving control commands. It is detachable and can be
operated externally and is connected via a cable to the inverter. Instead of the control keypad, a PC
can be used to control the inverter if connected through a similar cable (VACON RS232PC –1.5M).

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.

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

5. INSTALLATION

5.1 Mounting

The inverter can be mounted in either a vertical or horizontal position on a wall or on the back plane
of a cubicle. Enough space must be reserved around the inverter to ensure sufficient cooling, see
Figure 5-6. You must follow the minimum dimensions for installation, see Table 5-6 and Table 5-7.
Also make sure that the mounting plane is relatively even.

The inverter is fixed with four screws (or bolts, depending on the unit size). The dimensions for
installation are presented in Figure 5-6 and Table 5-6.

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.

The following pages show the dimensions for Vacon NX with a default enclosure in Figure 5-1, and
with flange mounting in Figures 5-2 and Figure 5-4. Dimensions for the opening needed in flange
mounting are given in Table 5-3 and Table 5-5.

5.2 Fan cooling

5.2.1 Frames FR4 to FR8

Enough free space must be left around the inverter to ensure sufficient air circulation and cooling.
You will find the required dimensions for free space in the table below.

If several units are mounted on top of each other, the required free space equals C + D (see figure
below). Moreover, the outlet air used for cooling by the lower unit must be directed away from the air
intake of the upper unit. When planning the cooling for the space, take into consideration that the
inverter’s heat loss is 2.5% of the nominal capacity.

5.2.2 Power losses as function of switching frequency

Raising the switching frequency of the drive, to reduce motor noise for example, inevitably affects
the power losses and cooling requirements as shown in the Figure below. It illustrates the power
loss FR7 as function of switching frequency. For more information, contact the Manufacturer or your
local distributor (see back cover).

6.1.1 Power connections

6.1.1.1 DC supply and motor cables

The power cables are connected to terminals DC+ and DC- (R+/B+ and DC terminals when using an
external charging circuit) and the motor cables to terminals U, V and W. A cable entry gland should
be used at the motor cable end to reach the EMC levels, see Table 6-1.

Use cables with a heat resistance of at least +60°C. The cables and the fuses must be sized
according to the inverter nominal output current which you can find on the rating plate. Installation
of cables according to UL regulations is presented in Chapter 6.1.3 and aR fuse sizes in Tables 6-2
and 6-3. The minimum dimensions of the Cu-cables are shown in Table 6-4.

If the motor temperature protection of the drive (see Vacon All in One Application Manual) is used as
an overload protection, the cable shall be chosen accordingly. If three or more cables are used in
parallel for bigger units, each cable requires a separate overload protection.

These instructions apply only to installations with one motor and one cable connection from the
inverter to the motor. In any other case, ask the factory for more information.

6.2 Control unit

The control unit of the inverter consists of the control board and option boards (see Figure 6-7 and
Figure 6-20) connected to the five slot connectors (A to E) on the control board. The control board is
connected to the power unit through a D connector (1).

A

Figure 6-7. control board Figure 6-8. Basic and option board connections

on the control board

When the inverter is delivered from the factory, the control unit usually includes two basic boards
(I/O board and relay board), which are normally installed in slots A and B. On the next pages you will
find the arrangement of the control I/O and the relay terminals of the two basic boards, the general

wiring diagram and the control signal descriptions. The I/O boards mounted at the factory are

indicated in the type code. For more information on the option boards, see Vacon NX option board
manual (ud741).

The control board can be powered externally (+24V) by connecting the external power source to
bidirectional terminal #6 (see Table 6-9). This voltage is sufficient for parameter setting and for
keeping the fieldbus active.

Note! If the +24V input of several inverters are connected in parallel, we recommend to use a diode
in terminal #6 to avoid the current to flow in opposite direction, which might damage the control
board.

6.2.2.1 Digital input signal inversions

The active signal level depends on which potential the common inputs CMA and CMB (terminals 11
and 17) are connected to. The alternatives are either +24V or ground (0 V). See Figure 6-13.
We recommend the use of positive logic in all control connections of the inverter. If negative logic is
used, additional appropriate measures are needed to meet the safety regulation requirements.

The 24 volt control voltage and the ground for the digital inputs and the common inputs (CMA, CMB)
can be either internal or external.

6.2.2.2 Jumper selections on the NXOPTA1 basic board

The user can customise the functions of the inverter to better suit his needs by selecting certain
positions for the jumpers on the NXOPTA1 board. The positions of the jumpers determine the signal
type of analogue and digital inputs.

On the A1 basic board, there are four jumper blocks (X1, X2, X3 and X6) each containing eight pins
and two jumpers. The selection possibilities of the jumpers are shown on page 43 (Figure 6-15).

7. CONTROL KEYPAD

The control keypad is the link between the Vacon inverter and the user. The Vacon NX control keypad
features an alphanumeric display with seven indicators for the Run status (RUN,

, READY,
STOP, ALARM, FAULT) and three indicators for the control place (I/O term/ Keypad/BusComm).
There are also three Status Indicator LEDs (green – green – red), see section 7.1.3.
The control information, i.e. the menu number, description of the menu or the displayed value and
the numeric information are presented on three text lines.

The inverter is operable through the nine push-buttons of the control keypad. Furthermore, the
buttons can be used in setting parameters and monitoring values.

The keypad is detachable and isolated from the input line potential.

The keypad reference submenu (P3.2) displays and allows the operator to edit the frequency
reference. The changes will take place immediately. This reference value will not, however,
influence the rotation speed of the motor unless the keypad has been selected as the active
control place.
NOTE: The maximum difference in RUN mode between the output frequency and the keypad
reference is 6 Hz. The program automatically monitors the keypad reference value.

Table 7-1. Fault types

This type of fault is a sign of an unusual operating
condition. It does not cause the drive to stop, nor does it
require any special actions. The 'A fault' remains in the
display for about 30 seconds.
An 'F fault' makes the drive stop. Actions need to be
taken to restart the drive.
If an 'AR fault' occurs the drive will stop immediately.
The fault is reset automatically and the drive tries to
restart the motor. Finally, if the restart is not successful,
a fault trip (FT, see below) occurs.
If the drive is unable to restart the motor after an AR
fault an FT fault occurs. The 'FT fault' has basically the
same effect as the F fault: the drive is stopped.

This function allows the user to change the timeout of the HMI acknowledgement time. The inverter
waits for the HMI acknowledgment in accordance with the value of this parameter.

Note! If the inverter has been connected to the PC with a normal cable, the default values of
parameters 6.7.3 and 6.7.4 (200 and 5) must not be changed.
If the inverter has been connected to the PC via a modem and there is a delay in transferring
messages, the value of parameter 6.7.3 must be set according to the delay as follows:

Example:

 Transfer delay between the inverter and the PC = 600 ms  The value of par. 6.7.3 is set to 1200 ms

(2 x 600, sending delay + receiving

delay)

 The corresponding setting shall be entered in the [Misc] part of the file

8. COMMISSIONING

8.1 Safety

Before commissioning, note the following directions and warnings:

WARNING

HOT SURFACE

8.2 Commissioning the inverter

Internal components and circuit boards of the inverter (except for the

1

galvanically isolated I/O terminals) 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.

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

2

are live when Vacon NX inverter is connected to DC supply, even if the
motor is not running.

The control I/O-terminals are isolated from the mains potential.

3

However, the relay outputs and other I/O-terminals may have a
dangerous control voltage present even when Vacon NX is disconnected
from DC supply.

Do not make any connections when the inverter is connected to the DC

4

supply.
After having disconnected the inverter, wait until the fan stops and the

5

indicators on the keypad go out (if no keypad is attached see the indicator
through the keypad base). Wait 5 more minutes before doing any work on
Vacon NX connections. Do not open the cover before the time has
expired.

Before connecting the inverter to DC supply make sure that the Vacon NX

6

front cover is closed.
When running, the side of inverter FR8 is burning hot. Do not touch it with

7

bare hands!
When running, the back of inverter FR6 is burning hot. Therefore it MUST

8

NOT be mounted onto a surface which is not fireproof.

1 Read carefully the safety instructions in Chapter 1 and above and follow them. 2 After the installation, make sure that:

both the inverter and the motor are grounded

the DC supply and motor cables comply with the requirements given in Chapter 6.1.1.

the control cables are located as far as possible from the power cables (see Chapter 6.1.2,

step 2) and the shields of the shielded cables are connected to protective earth
wires may not touch the electrical components of the inverter.

the common inputs of digital input groups are connected to +24V or ground of the I/O

terminal or the external supply.

3 Check the quality and quantity of cooling air (See Chapter 5.2 and Table 5-6). 4 Check the inside of the inverter for condensation. 5 Check that all Start/Stop switches connected to the I/O terminals are in Stop position.

6 Connect the inverter to DC supply. 7 Set the parameters of group 1 according to the requirements of your application (See

Vacon All in One Application Manual). At least the following parameters should be set:

motor nominal voltage
motor nominal frequency
motor nominal speed
motor nominal current

You will find the values needed for the parameters on the motor rating plate.

8 Perform run test without motor

Perform either Test A or Test B:

A Controls from the I/O terminals:
Turn the Start/Stop switch to ON position.
Change the frequency reference (potentiometer)
Check in the Monitoring menu M1 that the value of Output frequency changes according to

the change of frequency reference.

Turn the Start/Stop switch to OFF position.

9 Run the start-up tests without the motor being connected to the process. If this is not

possible, make sure that running each test is safe prior to running it. Inform your co­workers of the tests.

a)

Switch off the DC supply voltage and wait until the drive has stopped as advised in
Chapter 8.1, step 5.

b)

Connect the motor cable to the motor and to the motor cable terminals of the inverter.

c)

Make sure that all Start/Stop switches are in Stop positions.

d)

Switch the supply voltage ON

e)

Repeat test 8A or 8B.

10 Connect the motor to the process (if the start-up test was run without the motor being

connected)

a)

Before running the tests, make sure that this can be done safely.

b)

Inform your co-workers of the tests.

c)

Repeat test 8A or

9. FAULT TRACING

When a fault is detected by the inverter control electronics, the drive is stopped and the symbol F
together with the ordinal number of the fault, the fault code and a short fault description appear on
the display. The fault can be reset with the
The faults are stored in the Fault history menu M5, which can be browsed. The table below contains
all the fault codes.
