1.3 Grounding and earth fault protection
The VACON® NX inverter must always be earthed with an grounding conductor connected to the
grounding 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 capacity 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.

3.2 Storage
If VACON® NX Inverter is to be stored before use, make sure that the ambient conditions are
acceptable:
Storage temperature: -40...+158°F)
Relative humidity: 0 to 95%, no condensation
If you must keep the VACON® NX Active Front End in storage for a long time, you must connect the
power to the VACON® NX Active Front End each year. Keep the power on for a minimum of 2 hours.
We do not recommend a long storage time. If the storage time is more than 12 months, you must
charge the electrolytic DC capacitors with caution. To reform the capacitors, obey the instructions in
Chapter 3.2.1 Capacitor reforming.
3.2.1
Capacitor reforming
After a long storage time, it is necessary to reform the capacitors to prevent damage to the
capacitors. To make sure that the possible high leakage current through the capacitors stays in
minimum, use a DC-power supply with an adjustable current limit.
1. Set the current limit to 300-800mA to agree with the size of the drive.
2. Connect the DC-power supply to the B+/Bterminals (DC+ to B+, DC- to B-) of the DC-link or
directly to the capacitor terminals.
3. Set the DC-voltage to the nominal DC-voltage level of the Active Front End (1.35*Un AC) and
keep the power on for 1 hour, at minimum. If the Active Front End was in store for much longer
than 12 months and the capacitors were not charged, speak to the factory to get instructions
before you connect the power.
3.3 Maintenance
All technical devices, drives as well, need a certain amount of care-taking and failure preventive
maintenance. To maintain trouble-free operation of the drive, environmental conditions, as well as
load, line power, process control, etc. have to be within specifications, determined by manufacturer.
If all conditions are in accordance with the manufacturer's specifications, there are no other
concerns, but to provide a cooling capacity high enough for the power- and control circuits. This
requirement can be met by making sure, that the cooling system works properly. Operation of
cooling fans and cleanness of the heat sink should be verified regularly.
Regular maintenance is recommended to ensure trouble free operation and long lifetime of the
drive. At least the issues listed in the following table should be included in the regular maintenance.

maintenance.
3.4 Disposal
When the drive is at the end of its operation life, do not
discard it as a part of municipal waste. You can recycle
the primary components of the drive. You must
disassemble some components before you can remove
the different materials. Recycle the electrical and
electronic components as waste.
To make sure that the waste is recycled correctly, send
the waste to a recycling centre. You can also send the
waste back to the manufacturer. Obey the local and
other applicable regulations.

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.
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).

4.4 Derating
The output power has to be derated if one of following cases:

4.4.1
Ambient temperature
The power rating of the Active Front End unit is valid for an ambient temperature of 40 ºC (104 °F). If
the device is to be used in higher ambient temperatures, its power rating must be subjected to
derating. The derating coefficient from 40 °C to 50 °C, use derating factor 1.5 %/1 °C, and from 50 °C
to 55 °C, use derating factor 2.5 %/1 °C, for ambient temperatures not exceeding 55 °C (131 °F). The
reduced power is calculated using the formula:
Pde = Pn *((100% - (t - 40 ºC)*X)/100)
Pn = nominal power of the unit
t = ambient temperature
x = derating coefficient

High altitude installation
The density of air decreases when the altitude increases and the pressure decreases. When the air
density decreases, the thermal capacity decreases (i.e. less air removes less heat) and the
resistance to electric field (breakdown voltage / distance) decreases.

The full thermal performance of VACON® NX AC drives is designed for installation up to 1000 m
altitude and the electric insulation is designed for installations up to 2000 m altitude. Higher
installation locations are possible, when you obey the derating guidelines in this chapter.
NOTE! 690V units maximum installation altitude is 2000m.
Above 1000 m, you must decrease the limited maximum load current by 1% for each 100 m. Thus, for
example, at 2500 m altitude, you must decrease the load current down to 85% of the rated output
current (100% (2500 m 1000 m) / 100 m x 1% = 85%).
When you use fuses at high altitudes, the cooling effect of the fuse decreases as the density of the
atmosphere decreases.
When you use fuses above 2000 meters, the continuous rating of the fuse:
I = In*(1- (h-2000)/100*0.5/100)
I = Current rating at high altitude
In = Rated current of a fuse

5. INSTALLATION
5.1 Mounting
The inverter can be mounted in a vertical position on the back plane of a cubicle. Enough space must
be reserved around the inverter to ensure sufficient cooling, see Figure 5-7. Follow the minimum
dimensions for installation, see Table 5-1 and Table 5-2. 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 5-7 and Table 5-1.The following pages show the
dimensions for IP00 power module.

Enclosure sizes FI9 to FI14
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 2 * C (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

Table 5-2. Required cooling air
5.2.2
Arranging ventilation of the enclosure
The enclosure door must be provided with air gaps for air intake. To achieve sufficient cooling inside
the cabinet, the dimensions for the total area of free openings for incoming air given in Table 5-2
must be followed. For instance, there could be two screened gaps as presented in Figure 5-7 (our
recommendation). This layout ensures a sufficient air flow to the module fans as well as cooling of
the additional components.
Air outlet gaps must be situated on top of the cabinet. The minimum effective air outlet area per
converter enclosure is given in Table 5-2. The cooling arrangements inside the cabinet must be such
that they prevent hot output air from mixing with the incoming fresh air (see page 32).
The ventilation gaps must fulfil the requirements set by the selected IP class. The examples in this
manual apply to protection class IP21.
During operation, air is sucked in and circulated by a fan blower at the bottom of the power unit. If
the power unit is placed in the upper part of the cabinet, the fan blower will be in the mid of the
cabinet, at the height of the upper ventilation grid.
See Figure 5-7 on page 33.

STEERING AIR FLOW
Cooling air must be taken in through the ventilation gaps on the door and blown out at the top of the
enclosure. To steer the hot air from the power unit to the outlet at the top of the enclosure and
prevent it from circulating back to the fan blower, use either of the following arrangements:
A. Install a closed air duct from the power unit to the outlet on top of the enclosure (A in
figures below).
B. Install shields in the gaps between the power unit and the cabinet walls (B in figures
below). Place the shields above the air outlet gaps at the sides of the module.

6.1.1
Power connections
6.1.1.1 DC supply and motor cables
The power supply is connected to terminals B+ and B- and the motor cables to terminals U/T1, V/T2
and W/T3. 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 +70C. The cables and the fuses must be sized according
to the inverter nominal output current which can be found 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.
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.
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.

Installation instructions
1
Before starting the installation, check that none of the components of the
inverter are live.
2
In accordance with protection class IP00 requirements. There is no need
to install the inverter cover if the inverter is installed in a cubicle,
separate cabinet or device space.
3
Place the motor cables sufficiently far from other cables:
▪ Avoid placing the motor cables in long parallel lines with other
cables
▪ If the motor cables runs in parallel with other cables, note the
minimum distances between the motor cables and other cables
given in the table below.
▪ The given distances also apply between the motor cables and
signal cables of other systems.
▪ The maximum length of the motor cables is 300 m.
If output du/dt filters (+DUT option) are used the cable length is
limited according to the table below:
▪ The motor cables should cross other cables at an angle of 90
degrees.

Cable and motor insulation checks
1. Motor cable insulation checks
Disconnect the motor cable from terminals U, V, and W of the inverter and from the motor.
Measure the insulation resistance of the motor cable between each phase conductor as well as
between each phase conductor and the protective ground conductor.
The insulation resistance must be >1M.
2. DC supply cable insulation checks
Disconnect the DC supply cable from terminals DC- and DC+ of the inverter and from DC supply.
Measure the insulation resistance between each conductor and ground.
The insulation resistance must be >1M.
3. Motor insulation checks
Disconnect the motor cable from the motor and open the bridging connections in the motor
connection box. Measure the insulation resistance of each motor winding. The measurement
voltage must equal at least the motor nominal voltage but not exceed 1,000 V.
The insulation resistance must be >1M.

6.2 Control unit
The control unit of the inverter consists of the control board and option boards (see Figure 6-13 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).
Figure 6-13. control board Figure 6-14. 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 IO boards
User Manual.
6.2.1
Control voltage (+24V/EXT +24V)
It is possible to use the drive with an external power source with these properties: +24 VDC ±10%,
minimum 1000 mA. You can use it to externally power-up the control board, and the basic and
expander boards.
Connect the external power source to one of the 2 bidirectional terminals (#6 or #12), see Figure 48.
With this voltage, the control unit stays on and you can set the parameters. The measurements of
the main circuit (for example, the DC link voltage, and the unit temperature) are not available when
the drive is not connected to mains.
NOTE! If you supply the AC drive with external 24 V DC power, you must use a diode in terminal #6
(or #12) to prevent the current to flow in opposite direction. Put a 1 A fuse in 24 V DC line for each AC
drive. The maximum current consumption of each drive is 1 A from the external power supply.

Figure 6-15. Parallel connection of 24 V inputs with many AC drives
NOTE! The control unit I/O ground is not isolated from the chassis ground / protective earth. In the
installation, take into account the potential differences between the grounding points. We
recommend that you use galvanic isolation in the I/O and 24V circuitry.
NOTE! Analogue outputs and inputs do not work with only +24V supplied to the control unit.
If there is a +24V/EXT+24V output on the board, it is locally short-circuit protected. If one of the +24V/
EXT+24V outputs short-circuits, the others remain powered because of the local protection.
6.2.2
Control connections
The basic control connections for boards A1 and A2/A3 are shown in Chapter 0.
The inverters are equipped with A1 and A2 boards as standard.
The signal descriptions for the standard application are presented in Chapter 2 of the All in One
Application Manual. You can find the signal descriptions for other applications in the VACON® NX
Application Manual.

6.2.3.1 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 6-20.
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.

6.2.3.2 Jumper selections on the OPT-A1 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 OPT-A1 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 63 (Figure 6-22).

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.

7.3 Navigation on the control keypad
The data on the control keypad is arranged in menus and submenus. The menus are used for the
display and editing of measurement and control signals, parameter settings (see Chapter 7.3.2) and
reference value and fault displays (see Chapter 7.3.3.4). Through the menus, you can also adjust the
contrast of the display (see Chapter 7.3.6.6).
The first menu level consists of menus M1 to M7 and is called the
Main menu
. The user can navigate
in the main menu with the
Browser buttons
up and down. The desired submenu can be entered from
the main menu with the
Menu buttons
. When there still are pages to enter under the currently
displayed menu or page, you can see an arrow ( ) in the lower right corner of the display and can
reach the next menu level by pressing
Menu button right
.
The control keypad navigation chart is shown on the next page. Please note that menu M1 is located
in the lower left corner. From there you will be able to navigate your way up to the desired menu
using the menu and browser buttons.

7.3.2
Parameter menu (M2)
Parameters are the way of conveying the commands of the user to the inverter. Parameter values
can be edited by entering the
Parameter Menu
from the
Main Menu
when the location indication M2
is visible on the first line of the display. The value editing procedure is presented in Figure 7-5.
Pressing
Menu button right
once takes you to the Parameter Group Menu
(G#)
. Locate the desired
parameter group by using the Browser buttons and press
Menu button right
again to see the group
and its parameters. Use the
Browser buttons
to find the parameter (P#) you want to edit. Pressing
Menu button right
takes you to the edit mode. As a sign of this, the parameter value starts to blink.
You can now change the value in two different ways:
▪ Set the desired value with the
Browser buttons
and confirm the change with the
enter
button.
Consequently, the blinking stops and the new value is visible in the value field.
▪ Press
Menu button right
once more. Now you will be able to edit the value digit by digit. This may
come in handy, when a relatively greater or smaller value than that on the display is desired.
Confirm the change with the
enter
button.
The value will not change unless the Enter button is pressed. Pressing
Menu button left
takes
you back to the previous menu.
Several parameters are locked, i.e. cannot be edited, when the drive is in RUN status. If you try to
change the value of such a parameter the text
*Locked*
will appear on the display. The inverter
must be stopped to edit these parameters.
The parameter values can also be locked using the function in menu M6 (see Chapter6.5.2)).
You can return to the Main menu any time by pressing
Menu button left
for 1 to 2 seconds.
The basic application package "All in One+" includes seven applications with different sets of
parameters. You will find the parameter lists in the Application Section of this manual.
Once in the last parameter of a parameter group, you can move directly to the first parameter of that
group by pressing
Browser button up
.
See the diagram for parameter value change procedure on page 72.
Note: You can connect power to the control board by connecting the external power source to the
bidirectional terminal #6 on the OPT-A1 board (see page 60). The external power source can also be
connected to the corresponding +24V terminal on any option board. This voltage is sufficient for
parameter setting and for keeping the fieldbus active.

7.3.3.2 Keypad reference
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.
See also Chapter 7.3.3.
Figure 7-5 shows how to edit the reference value (pressing the
enter
button is not necessary).
7.3.3.3 Keypad direction

7.3.3.4 Stop button activated
By default, pushing the STOP button will always stop the motor regardless of the selected control
place. You can disable this function by giving parameter 3.4 the value 0. If the value of this parameter
is 0, the STOP button will stop the motor only when the keypad has been selected as the active
control place.
Note: For additional information on controlling the motor with the keypad, see Chapters 7.2.1, 7.3.3
and 8.2.
NOTE!
There are some special functions that can be performed in menu M3:
Select the keypad as the active control place by pressing START for 3 seconds when
the motor is running. The keypad will become the active control place and the current
frequency reference and direction will be copied to the keypad.
Select the keypad as the active control place by pressing STOP for 3 seconds when
the motor is stopped. The keypad will become the active control place and the current
frequency reference and direction will be copied to the keypad.
Copy the frequency reference set elsewhere (I/O, fieldbus) to the panel by pressing
enter
for 3 seconds.
Note that if you are in any other than menu M3 these functions will not work.

7.3.4
Active faults menu (M4)
You can enter the Active faults menu from the Main menu by pressing
Menu button right
when the
location indication M4 is visible on the first line of the keypad display.
When a fault brings the inverter to a stop, the location indication F1, the fault code, a short
description of the fault, and the fault type symbol (see Chapter 7.3.4.1) will appear on the display. In
addition, the indication FAULT or ALARM (see Figure 7-1 or Chapter 7.1.1) is displayed and, in case
of a FAULT, the red LED on the keypad starts to blink. If several faults occur simultaneously, the list
of active faults can be browsed with the
Browser buttons
.
The memory of active faults can store a maximum of 10 faults in the order of appearance. The
display can be cleared with the
reset
button and the read-out will return to the same state it was in
before the fault trip. The fault remains active until it is cleared with the
reset button
or with a reset
signal from the I/O terminal.
Note! Remove external Start signal before resetting the fault to prevent unintentional restart of the
drive.

Fault type symbol
Meaning
A
(Alarm)
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.
F
(Fault)
An 'F fault' makes the drive stop. Actions need to be
taken to restart the drive.
AR
(Fault Autoreset)
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.
FT
(Fault Trip)
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.

7.3.6.7 Hardware settings
NOTE:
The Hardware settings submenu
is protected with a password. Store the password in a safe
place!
In the
Hardware settings
submenu (S6.7) under the System menu, you can further control some
functions of the hardware in your inverter. The functions available in this menu are
Internal brake
resistor connection, Fan control, HMI acknowledge timeout and HMI retry.
Internal brake resistor connection (P6.7.1)
This function tells the inverter, whether the internal brake resistor is connected or not. If you have
ordered the inverter with an internal brake resistor, the default value of this parameter is
Connected
. However, if it is necessary to increase braking capacity by installing an external brake
resistor, or if the internal brake resistor is disconnected for another reason, it is advisable to change
the value of this function to
Not conn.
in order to avoid unnecessary fault trips.
Enter the edit mode by pressing
Menu button right
. You can change the brake resistor information
with the
Browser buttons
. Confirm the change with the
enter
button or return to the previous level
with
Menu button left
.
Note! The brake resistor is available as optional equipment for all classes. It can be installed
internally in classes FR4 to FR6.
Figure 7-21. Internal brake resistor connection
Fan control (P6.7.2)
This function allows you to control the cooling fan of the inverter. You can set the fan to run continuously when the power is switched on or depending on the temperature of the unit. If the latter
function has been selected, the fan is switched on automatically when the heatsink temperature
reaches 60C. The fan receives a stop command when the heatsink temperature falls to 55C. After
the command, the fan runs for approximately 1 minute before stopping. The same happens after
switching on the power and after changing the value from
Continuous
to
Temperature
.
Note! The fan runs always when the drive is in RUN state.

HMI acknowledge timeout (P6.7.3)
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
NCDrive.ini:
Retries = 5
AckTimeOut = 1200
TimeOut = 6000
▪ It must also be considered that intervals shorter than the AckTimeOut time
cannot be used in NC-Drive monitoring.
Enter the edit mode by pressing
Menu button right
. The current value starts to blink. Use the
Browser buttons
to change the acknowledgement time. Confirm the change with the
enter
button or
return to the previous level with Menu button left.
