1. SAFETY

ONLY A COMPETENT ELECTRICIAN MAY CARRY OUT THE ELECTRICAL INSTALLATION

= DANGEROUS VOLTAGE!

= WARNING or CAUTION

1.1 Warnings

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

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

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.

The frequency converter has a large capacitive leakage current.

If the frequency converter 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 motor starts at power-up if the start command is 'ON'. 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.

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

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

1.2 Safety instructions

The components of the power unit of the frequency converter and all cabinet mounted devices are potentially 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 –/+ and all other mains devices are potentially live when Vacon NX is connected to mains, even if the motor is not running.

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 cabinet door before this time has expired.

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.

Before connecting the frequency converter to mains make sure that the Vacon NX front and cable covers as well as the cabinet doors are closed.

NOTE! 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.

1.3 Earthing and earth fault protection

The Vacon NX frequency converter must always be earthed with an earthing conductor connected to the PE bar in the lower front side of the cabinet.

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.

NOTE! Due to the high capacitive currents present in the frequency converter, fault current protective switches may not function properly.

3.3 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 Relative humidity <95%, no condensation

The environment should also be free from dust. If there is dust in the air the converter should be well protected to make sure dust does not get into the converter.

If the converter is to be stored during longer periods the power should be connected to the converter once in 24 months and kept on for at least 2 hours. If the storage time exceeds 24 months the electrolytic DC capacitors need to be charged with caution. Therefore, such a long storage time is not recommended.

If the storing time is much longer than 24 months, the recharging of the capacitors has to be carried out so that the possible high leakage current through the capacitors is limited. The best alternative is to use a DC-power supply with adjustable current limit. The current limit has to be set for example to 300…500mA and the DC-power supply has to be connected to the B+/B- terminals (DC supply terminals).

DC-voltage must be adjusted to nominal DC-voltage level of the unit (1.35*Un AC) and supplied at least for 1 hour.

If DC-voltage is not available and the unit has been stored de-energized much longer than 1 year consult factory before connecting power.

5.2 Lifting the unit out of the transport packaging

The unit is delivered either in a wooden box or a wooden cage. The box may be transported either horizontally or vertically, while transportation of the cage in a horizontal position is not allowed. Always refer to shipping marks for more detailed information. To lift the unit out of the box, use lifting equipment capable of handling the weight of the cabinet.

There are lifting lugs on the top of the cabinet and these lugs can be used to lift the cabinet into an upright position and to move it to the place needed.

Figure 3. Lifting the unit

NOTE! Location of lifting lugs varies between different frames. Recycle the packaging material according to local regulations.

5.3 Fixing the unit to the floor or to the wall

Before starting the installation work make sure that the level of the floor is within acceptable limits. The maximum deviation from the basic level can be no more than 5 mm over 3 m distance. The maximum acceptable height difference between cabinet front and rear edges should be within +2/

-0mm limit. The cabinet should always be fixed to the floor or to the wall. Depending on installation conditions,

the cabinet sections can be fixed in different ways. There are holes in the front corners which can be used for fixing. Additionally, the rails on the top of the cabinet have fixing lugs for fixing the cabinet to the wall.

Welding of the cabinet might risk sensitive components in the converter. Ensure that no earthing currents can flow through any part of the converter.

5.3.1 Fixing to the floor and to the wall

In installations where the cabinet is mounted against the wall, it is more convenient to fix the top of the cabinet to the wall. Fix the cabinet in the two front corners to the floor with bolts. Fix the top part to the wall with bolts. Note that the rails and the fixing lugs can be moved horizontally to make sure the cabinet stands in a horizontal position. In converters consisting of more than one cabinet section, fix all sections in the same way.

5.4 AC choke connections

NOTE! The NXC low-harmonic drive incorporates an LCL filter instead of AC chokes and this instruction can be ignored.

The AC input choke carries out several functions in the Vacon NX 6- and 12-pulse frequency converter. The input choke is needed as an essential component for motor control, to protect the input and DC-link components against abrupt changes of current and voltage as well as to function as a protection against harmonics.

The NXC 6- and 12-pulse frequency converter is equipped with one or more input AC chokes. The chokes have two inductance levels to optimise the functionality at different supply voltages. In the installation phase, the wiring of the chokes should be checked and changed if needed (not for FR9).

The input is always connected to terminal #1 (see picture below) and should not be changed. The output of the choke should be connected to terminal #2 or #3 (see picture below) according to the table below. The terminals are marked with inductance values and applicable voltage.

In units FR10 to FR12, the connection is changed by moving the cable to the appropriate terminals. In FR13/14, the bridges of the busbar connection should be moved according to the settings shown in the table.

In units with two or more parallel chokes (some FR11 as well as all FR12 and FR13) all chokes have to be wired in the same way. If chokes are wired differently the converter may be damaged.

5.5 Auxiliary voltage transformer tappings

NOTE! An auxiliary voltage transformer is always included as standard in NXC low-harmonic drives. If the drive is ordered with an auxiliary voltage transformer for 230V auxiliary voltage supply (+ATx

option) the tappings of the transformer have to be set according to the mains voltage. The tappings of the transformer in 500V drives is by default set to 400V or 500V and in 690V drives

to 690V unless otherwise ordered. Locate the transformer in the lower part of the cabinet. The primary side of the transformer has

tappings that correspond to standard main voltages. Change to tapping to correspond to the mains voltage in use.

5.7 Power losses

The power loss of the frequency converter varies greatly with load and output frequency as well as with the switching frequency used. For dimensioning of cooling or ventilation equipment for electrical rooms the following generic formula gives a good approximation of the heat losses for NXC 6- and 12-pulse drives at nominal conditions.

[kw] = P

loss

Heat losses of NXC low-harmonic drives are roughly 1,5...2 times more compared to 6-p and 12pulse. Additional information on heat losses for specific frame size and current class is available on request.

6.1 Understanding the power unit topology

Figure 9 and Figure 10 show the principles for mains and motor connections of the basic 6-pulse drive in frame sizes FR10 to FR14.

Some units built in frame size FR11 have double input devices and require an even number of supply cables but an uneven number of motor cables can be used.

Units built in frame size FR12 consist of two power modules and require an even number of supply and motor cables. See Figure 9 and the tables in Chapter 6.2.6.

The 12-pulse drives always have a double set of inputs. The motor connection is size dependent as described above and in Figure 9.

6.2.1 LCL filter wiring diagram of NXC low-harmonic drive

The LCL filter in the NXC low-harmonic drive contains a choke on the mains side, capacitors and a choke on the AFE side. The LCL filter also includes capacitors connected against ground potential. There are resistors connected across the capacitors for discharging these when the LCL filter is disconnected from the input power.

Figure 11. Vacon LCL filter wiring diagram

6.2.1.1

Removing HF capacitors

If a PWM modulated rectifier of another manufacturer is connected to the same input transformer, the capacitors must be removed. Otherwise the capacitors must not be removed.

Figure 12 ( AF9, AF10 and AF12) and Figure 13 (AF13 and AF14) have a red marking on the lead that has to be removed from each capacitor if the interference suppression capacitors are not to be used. Removing the lead disconnects the capacitors from ground potential.

6.2.2 Mains and motor cables

The mains cables are connected to terminals L1, L2 and L3 (12-pulse units 1L1, 1L2, 1L3, 2L1, 2L2, 2L3) and the motor cables to terminals marked with U, V and W, see Figure 15.

In converters consisting of double input sections, an even number of input cables is required. In converters consisting of double power modules an even number of motor cables is needed. See Table 13 to Table 17 for cabling recommendations.

In 12-pulse drives with double inputs or outputs it is very important that the same cable dimensions, type and routing is used for all cables. In case the cabling between the converter modules is not symmetrical, unequal load might occur and reduce loadability or even damage the converter.

In units with double motor outputs the motor cables must not be connected together in the converter end. Always connect the parallel motor cables together in the motor end only. The minimum motor cable length is 5 m.

If a safe switch between the frequency converter and the motor is used, make sure that it is switched on before setting the frequency converter in run state.

The output cables to the motor must be 360

EMC earthed. Separate EMC earthing clamps are supplied with NXC FR9 if an output filter is used and with all drives of sizes FR/AF10-12. In NXC FR/ AF13-14, EMC earthing is implemented directly through cable glands and earthing clamps are unnecessary. See Chapter 6.2.2.1 for more information on EMC earthing for FR/AF13-14.The EMC earthing clamps can, for instance, be installed on the mounting plate in front of the AC choke as shown in Figure 14 below. The EMC earthing clamps must be suited to the output cable diameter to

give a 360

contact with the cables. See Chapters 6.2.6 and 6.2.7 for output cable diameters. See

Figure 14.

For more detailed cable installation instructions, see Chapter 8, step 6. Use cables with a temperature rating of at least +70

°C. As a rule of thumb, cables and the fuses

can be dimensioned according to the frequency converter nominal OUTPUT current which you can find on the rating plate. Dimensioning according to the output current is recommended because the frequency converter input current never significantly exceeds the output current.

Table 13 and show the minimum dimensions of Cu- and Al-cables and the recommended aR fuse sizes.

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

Installing the cable gland

Unless the cable gland is already installed by the manufacturer, follow the procedure below to do this:

1. Assemble the rubber sealing in the narrow groove of the bush ring. Make sure that the gap between the assembly plate and the sealing is tight.

2. Since the fastening spring is rather stiff, we recommend to use a cone-shaped tool to fit the metal sock in the bush ring and then to clamp it with the spring bent into a ring shape. Draw the sock over the groove far enough to be easily fastened with the spring. Make sure that the spring clamps the sock at 360°.

3. Roll up the sock as far as the fastening ring and remove the cone-shaped tool if used. Now the cable installation is easier and the cable will not damage the sock.

4. Clamp the sock to the shielding of cable with a cable tie.

6.2.4 DC supply and brake resistor cables

Vacon 6- and 12-pulse frequency converters can optionally be equipped with terminals for DC supply and with an external brake resistor. These terminals are marked with B-, B+/R+ and R-. The DC bus connection is made to terminals B– and B+ and the brake resistor connection to R+ and R– on the converter module. The converter module terminals can also optionally be wired to customer terminals in the cabinet. For additional information on integrated brake chopper and resistor values please refer to NXS/NXP manual.

Make sure that the converter is equipped with a brake chopper before connecting a brake resistor.

Do not connect the brake resistor between the terminals B- and B+ as this will damage the drive.

7. LOW HARMONIC CABINET DRIVE

This chapter describes the functionalities of control devices (switches, push-buttons and LED lamps) of the NXC low-harmonic drive (mechanical units AF9-14).

7.1 NXC Low-Harmonic Cabinet Pre-Charging and MCCB Operating Instructions

There are three different ways to control the DC pre-charging circuit and the circuit-breakers (MCCB) of the low harmonic drive. The desired control place or the manner of control can be selected with the are:

REM-MAN-AUTO

selector switch (-S6). The three possible control places/ways

• MAN – Manual operation by the

• REM – Remote operation with signals to the control terminals

• AUTO – Automatic operation which automatically pre-charges and closes the MCCB when the supply voltage is energized

8. INSTALLATION INSTRUCTIONS

Before starting the installation, check that none of the components of the frequency converter is live.

Make sure that the space where the converter is installed, and the converter itself, is clean and free from particles, dust or humidity that could harm the converter when it is powered on.

Make sure the connection of the AC choke and the optional 230 V auxiliary voltage transformer are suitable for the supply voltage in use (See Chapter 5.4).

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 run in parallel with other cables, note the minimum distances between the motor cables and other cables given in 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 (+ODU or +ODC options) 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.

If cable insulation checks are needed, see Chapter 8.1.1.

INSTALLATION INSTRUCTIONS vacon • 57

Connect the cables:

• Strip the motor and mains cables .

• Remove the protection grids for the input terminals and the protection covers on the converter module(s).

• Pull the cable through the bottom plate and fix the PE conductor to the PE bar of the cabinet.

• Connect the mains, motor and control cables into their respective terminals. Use cable lugs on the power cables. In units with parallel cables (FR11 and FR12) make sure the cabling is fully symmetrical.

• Fix the shields of the motor cable(s) to the cabinet by using the earthing clamps included in the delivery.

• For Information on cable installation according to UL regulations see Chapter

8.1.

• Make sure that the control cable wires do not come in contact with the electronic components of the unit or control components inside the cabinet.

• If an external brake resistor (option) is used, connect its cable to the appropriate terminal (R+/R–). Also make sure that the converter is equipped with a brake chopper (indicated in the type code of the converter).

• Check the connection of the earth cable to the motor and the frequency

converter terminals marked with PE or .

• Connect the separate shield of the power cable to the earth terminals of the frequency converter, motor and the supply centre.

IMPORTANT! If an output filter (+ODU, +ODC or +OSI) is used, note that the switching frequency of the converter (parameter 2.6.9, ID601) must be set according to the specification of the output filter. Setting too high/low a switching frequency may damage the filter.

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 >1 MΩ..

2. Mains cable insulation checks

Disconnect the mains cable from terminals L1, L2 and L3 of the frequency converter and from the mains. Measure the insulation resistance of the mains cable between each phase conductor as well as between each phase conductor and the protective ground conductor. The insulation resistance must be >1 MΩ..

3. Brake resistor cable insulation checks

Disconnect the brake resistor cable from terminals R+ and R- of the frequency converter and from the brake resistor. Measure the insulation resistance of the cable between each conductor as well as between conductors and the protective ground conductor. The insulation resistance must be >1 MΩ..

4. 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 1000 V. The insulation resistance must be >1 MΩ.

board. The control board is connected to the power unit through a D-connector (1) or fibre optic cables.

(A to E) of the control

Figure 31. NXP control board Figure 32. Basic and option board connections

on the control board

Usually, when the frequency converter is delivered from the factory, the control unit includes at least the standard compilation of 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 (+24 V, ±10%) by connecting the external power source to either of the bidirectional terminala #6 or #12, see page 63. This voltage is sufficient for parameter setting and for keeping the fieldbus active.

NOTE! Each AFE module of a NXC low-harmonic drive has its own control unit. The three basic boards A1,A2 and B5 are included as standard. AFE control usually needs to be parameterized only once during the commissioning of the drive.

NOTE! If the 24 V inputs of several frequency converters are parallelly connected we recommend to use a diode in terminal #6 (or #12) in order to avoid the current to flow in opposite direction. This might damage the control board. See picture below.

8.3 Connecting power supply and internal control cables

You might need to establish the fibre cable connections from the star coupler board to the power module. Connect the cables according to Figure 41.

The control unit uses 24 VDC supplied from the ASIC board, which is located on the left side of the power unit 1. To access the board, remove the protective cover in front of the power module. Connect the power supply cable to the X10 connector on the ASIC board and to the X2 connector on the rear side of the control unit.

Figure 40. Connecting the power supply and control cables to the control unit, FR12

Each fibre optic cable has a number 1...8 and 11…18 marked on the cable shield at both cable ends. Connect each cable to the connectors marked with the same number on the ASIC board and on the rear side of the control unit. Additionally, you may have to connect the 4 fibre cables from the feedback board to the star coupler board. The list of the optic signals can be found in Chapter 8.4.

CAUTION!

NOTE!

Be careful when connecting the fibre optic cables! Connecting the wires incorrectly will damage power electronic components.

The minimum bending radius for optical cables is 50 mm.

Fix the cable bundle at two or more points, at least one at each end, to prevent damages to the cables.

Fasten the protective cover on the power unit when the work is finished.

The control keypad is the link between the Vacon frequency converter 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 Status LEDs (green – green – red) below.

The control information, i.e. the number of menu, description of menu or the displayed value and the numeric information are presented on three text lines.

The frequency converter is operable through the nine push-buttons of the control keypad. Furthermore, the buttons serve the purposes of parameter setting and value monitoring.

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

9.3.4.1 Fault types

In the NX frequency converter, there are four different types of faults. These types differ from each other on the basis of the subsequent behaviour of the drive. See Table 26.

Figure 48. Fault display

Table 26. Fault types

Fault type symbol Meaning

(Alarm)

(Fault)

(Fault Autoreset)

(Fault Trip)

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' is a kind of fault that makes the drive stop. Actions need to be taken in order to restart the drive.

If an 'AR fault' occurs the drive will also 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 effect of the 'FT fault' is basically the same as that of the F fault: the drive is stopped.

When the Parameter backup function is activated Vacon NX control keypad makes a copy of the parameters of the presently used application. Every time a parameter is changed the keypad backup is automatically updated.

When applications are changed, you will be asked if you wish the parameters of the new application to be uploaded to the keypad. For this to happen, push the of the parameters of the previously used application saved in the keypad push any other button. Now you will be able to download these parameters to the drive following the instructions given in Chapter 9.3.6.3.

If you want the parameters of the new application to be automatically uploaded to the keypad you have to do this for the parameters of the new application once on page 6.3.2 as instructed. Otherwise the panel will always ask for the permission to upload the parameters.

NOTE! Parameters saved in the parameter settings on page S6.3.1 will be deleted when applications are changed. If you want to transfer the parameters from one application to another you have to upload them first to the keypad.

HMI acknowledge timeout (P6.7.3)

This function allows the user to change the timeout of the HMI acknowledgement time in cases where there is an additional delay in the RS-232 transmission due to use of modems for communication over longer distances, for example.

NOTE! If the frequency converter has been connected to the PC with a normal cable, the default values of parametres 6.7.3 and 6.7.4 (200 and 5) must not be changed.

If the frequency converter has been connected to the PC via a modem and there is delay in transferring messages, the value of par. 6.7.3 must be set according to the delay as follows:
