1. SAFETY

ONLY A COMPETENT ELECTRICIAN MAY CARRY OUT THE ELECTRICAL INSTALLATION

= DANGEROUS VOLTAGE!

= WARNING or CAUTION

1.1 Warnings

The VACON

NX AC drive is meant for fixed installations only.

Do not perform any measurements when the AC drive 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 AC drive has a large capacitive leakage current.

If the AC drive 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 the manufacturer 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 AC drive.

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 AC drive and all cabinet mounted devices are potentially live when VACON

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

even if the motor is not running. After disconnecting the AC drive 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

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 AC drive to mains make sure that the VACON 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 grounding and earth fault protection

The VACON® NX AC drive must always be earthed with an grounding conductor connected to the PE bar in the lower front side of the cabinet.

The earth fault protection inside the AC drive 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 AC drive, fault current protective switches may not function properly.

3.3 Storage

If the AC drive 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 AC drive should be well protected to make sure dust does not get into the AC drive.

If the AC drive is to be stored during longer periods the power should be connected to the AC drive 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.

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 AC drive. Ensure that no grounding currents can flow through any part of the AC drive.

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 AC drives consisting of more than one cabinet section, fix all sections in the same way.

5.3.2 Fixing to the floor only

NOTE! This option is not available for FR13 and bigger units. For fixing FR13 and bigger units see delivery specific documentation.

If bottom-only fixing is used, additional fixing brackets (Rittal part.nr. 8800.210) or equivalent are necessary. Fix the cabinet to the floor in the front with bolts and use the fixing brackets in the middle. Fix all cabinet 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 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 AC drive 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 AC drive 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 AC drive 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 enclosure 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 enclosure sizes FR10 to FR14.

Some units built in enclosure 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 enclosure 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 AC drives consisting of double input sections, an even number of input cables is required. In AC drives 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 AC drive modules is not symmetrical, unequal load might occur and reduce loadability or even damage the AC drive.

In units with double motor outputs the motor cables must not be connected together in the AC drive 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 AC drive and the motor is used, make sure that it is switched on before setting the AC drive in run state.

The output cables to the motor must be 360

EMC earthed. Separate EMC grounding 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 grounding is implemented directly through cable glands and grounding clamps are unnecessary. See Chapter 6.2.2.1 for more information on EMC grounding for FR/AF13-14.The EMC grounding clamps can, for instance, be installed on the mounting plate in front of the AC choke as shown in Figure 14 below. The EMC grounding 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 AC drive nominal OUTPUT current which you can find on the rating plate. Dimensioning according to the output current is recommended because the AC drive 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.

In case of parallel motor cables, reserve an equal amount of ferrite ring sets for each cable and feed all the phase conductors of one cable through one set of rings.

The delivery consists of fixed sets of ferrite rings (option). When ferrite rings are used to attenuate the risk of bearing damages, use always two ferrite ring sets per motor cable.

NOTE! The ferrite rings are only additional protection. The basic protection against bearing currents is an insulated bearing.

The DC bus connection is made to terminals B– and B+ and the brake resistor connection to R+ and R– on the AC drive module. The AC drive 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 AC drive 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.

LOW HARMONIC CABINET DRIVE vacon • 53

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 REM-MAN-AUTO selector switch (-S6). The three possible control places/ways are:

• MAN – Manual operation by the 0-1-Start switch on the cabinet door

• 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

Figure 25. MCCB Control selector switch (-S6)

Local contacts: http://drives.danfoss.com/danfoss-drives/local-contacts/

vacon • 54 LOW HARMONIC CABINET DRIVE

11507_00

7.1.1 Manual operation (MAN)

The operator can control the circuit-breaker (MCCB) and the charging circuit manually from the cabinet while the MCCB control switch –S6 is in Man position. The 0–1-Start switch is used for the local operation of the MCCB and pre-charging circuit.

Figure 26. 0-1-Start Control switch (-S10)

Turning the switch –S10 into position 0 will open the circuit-breaker if it is closed or stop the possible ongoing pre-charging regardless of the selected control place/manner.

Turning the switch into position 1 enables the pre-charging and the circuit-breaker to be controlled by the selected mode of the REM-MAN-AUTO selector switch.

Turning the switch into position Start will start the pre-charging of DC busbar. The pre-charging takes about 5-10 s depending on the size of the drive. When DC voltage has reached a certain level the AFE control unit will automatically close the circuit-breaker. The Start position of the switch is spring-retuned and the switch will automatically return to position 1 when released. The precharging can be aborted by turning the switch to position 0. In case of a blackout in the supplying network, the under-voltage release coil will open the circuit-breaker. Pre-charging and MCCB closing have to be activated by the operator when the supply is energized.

The AFE Ready LED will illuminate when the MCCB is closed and AC power is connected to the AFE unit and there are no active faults. The AFE ready LED works in the same way irrespective of the operation manner/place.

Figure 27. AFE Ready indicator

The Run command has to be given to the AFE unit from the keypad, I/O signal or bus communication before the inverter INU can be started (operated).

7.1.2 Remote operation (REM)

It is possible to control the circuit-breaker and the charging circuit from a remote location/system with potential-free contacts while the MCCB control switch –S6 is in REM position.

Normally closed (NC) contact has to be connected to terminals X1:60 and X1:61 (terminal name can vary depending on the enclosure size). This contact has to be in the NC state before the pre-charging can be activated. Opening this contact will open circuit-breakers and stop the ongoing pre-charging.

A remote pulse duration (0.4-1s) connected to terminals X1:57 and X1:58 will start the charging of the drive, and when DC voltage has reached a certain level, the AFE unit will automatically close the circuit-breakers (terminal name can vary depending on the enclosure size). The Run command has to be given to the AFE unit from the keypad, I/O signal or bus communication before the inverter INU can be started (operated).

Figure 28. Circuit diagram of remote contacts for the control of the MCCB and pre-charging

circuit (NXC low-harmonic FR12)

In case of a voltage drop of <0.7xUN or a blackout in the supplying network, the undervoltage release coil will open the circuit-breaker and pre-charging and MCCB closing has to be activated by the remote charging pulse when the supply is energized.

7.1.3 Automatic operation (AUTO)

The pre-charging and closing of the circuit-breaker is automatically done when the REM-MANAUTO selector switch is in AUTO position and the supply voltage is energized. The pre-charging of the units will automatically (directly) start when the control switch -S6 is turned into Auto position. The AFE unit will automatically close the circuit-breakers after DC voltage has reached a certain level and the AFE READY LED will illuminate.

The unit will re-charge automatically and close the circuit-breakers if the main supply voltage has been cut and turned back on (e.g. voltage drop in the network). The 0-1-Start switch has to be in position 1 which enables automatic function.

Turning the switch –S10 to position 0 will open the circuit-breaker even if the REM-MAN-AUTO selector switch is in AUTO position.

7.1.4 Circuit-Breaker TRIP due to overload or short-circuit

The electronic trip unit will open/trip the circuit-breaker in case of an overload or short circuit. The trip indication contacts of circuit-breakers are connected in series and if one of the circuit-breakers trips due to an overload or short circuit current, it will automatically open/trip the other circuitbreakers. The MCCB FAULT LED will illuminate and indicate that the circuit breakers are in tripped state.

Figure 29. MCCB FAULT indicator

In case of an overcurrent situation the fault that caused the circuit-breaker to trip should be identified and removed before the circuit-breakers can be reset. The MCCB can only be reset by pressing the push button -S6 when the –S11 REM-MAN-AUTO switch is in MAN position.

Figure 30. MCCB Reset push-button (-S11)

This will reset the circuit-breaker and, at the same time in FR9, FR10 or FR12 solution, recharge the spring system of the motor operators. After this it is possible to pre-charge and close the circuitbreakers by methods described in previous chapters.

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 • 59

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 grounding 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 AC drive

terminals marked with PE or .

• Connect the separate shield of the power cable to the earth terminals of the AC drive, 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.

8.1.1 Cable and motor insulation checks

1. Motor cable insulation checks

Disconnect the motor cable from terminals U, V and W of the AC drive 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 >1 MΩ..

2. Mains cable insulation checks

Disconnect the mains cable from terminals L1, L2 and L3 of the AC drive 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 AC drive 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.

5. Brake resistor insulation check

Disconnect the brake resistor cable and measure the insulation from the power terminals to the ground terminal. The measurement voltage must equal at least the motor nominal voltage but not exceed 1000 V. The insulation resistance must be >1MΩ.

8.2 Control unit

The control unit of the AC drive consists roughly of the control board and additional boards (see Figure 31 and Figure 32) connected to the five slot connectors (A to E) of the control board. The control board is connected to the power unit through a D-connector (1) or fibre optic cables.

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

on the control board

Usually, when the AC drive 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.

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 65. 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 AC drives 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® AC drive 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 AC drive 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.

The data on the control keypad are arranged in menus and submenus. The menus are used for example for the display and editing of measurement and control signals, parameter settings (Chapter 9.3.2), reference values and fault displays (Chapter 9.3.4). Through the menus, you can also adjust the contrast of the display (page 93).

The first menu level consists of menus M1 to M7 and is called the Main menu. The user can navigate in the main menu using the Browser buttons up and down. The desired submenu can be entered from the main menu using 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 by pressing the Menu button right, you can reach the next menu level.

The control keypad navigation chart is shown on the next page. Please note that the 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.

More detailed descriptions of the menus you will find later in this Chapter.

M1.17 Multimonitoring items

Displays three selectable monitoring values. See Chapter

9.3.6.5.

NOTE! The All in One applications embody more monitoring values.

9.3.2 Parameter menu (M2)

Parameters are the way of conveying the commands of the user to the AC drive. The 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 46.

Push the Menu button right once to move into the Parameter Group Menu (G#). Locate the parameter group desired by using the Browser buttons and push the Menu button right again to enter the group and its parameters. Use again the Browser buttons to find the parameter (P#) you want to edit. From here you can proceed in two different ways: Pushing the 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 manners:

1 Just set the new 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.

2 Push the Menu button right once again. Now you will be able to edit the value digit by digit.

This editing manner 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 pushed. Pressing the Menu button left takes you back to the previous menu.

Several parameters are locked, i.e. uneditable, 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 AC drive must be stopped in order to edit these parameters.

The parameters values can also be locked using the function in menu M6 (see Chapter Parameter lock (P6.5.2)).

You can return to the Main menu anytime by pressing the Menu button left for 3 seconds. The basic application package "All in One" includes seven applications with different sets of

parameters. See the All in One Application manual for closer information. Once in the last parameter of a parameter group, you can move directly to the first parameter of that

group by pushing the Browser button up. See the diagram for parameter value change procedure on page 78.

9.3.4.1 Fault types

In the NX AC drive, 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.

The Fault history menu can be entered from the Main menu by pushing the Menu button right when the location indication M5 is visible on the first line of the keypad display. Find the fault codes in Table 37.

All faults are stored in the Fault history menu in which you can browse through them using the Browser buttons. Additionally, the Fault time data record pages (see Chapter 9.3.4.2) are accessible at each fault. You can return to the previous menu anytime by pushing the Menu button left.

The memory of the AC drive can store a maximum of 30 faults in the order of appearance. The number of faults currently in the fault history is shown on the value line of the main page (H1H#). The order of the faults is indicated by the location indication in the upper left corner of the display. The latest fault carries the indication F5.1, the second latest F5.2 etc. If there are 30 uncleared faults in the memory the next occurring fault will erase the oldest from the memory.

9.3.6.3

The parameter copy function is used when the operator wants to copy one or all parameter groups from one drive to another or to store parameter sets in the internal memory of the converter. All the parameter groups are first uploaded to the keypad, then the keypad is connected to another drive and then the parameter groups are downloaded to it (or possibly back to the same drive).

Before any parameters can successfully be copied from one drive to another the drive has to be stopped when the parameters are downloaded to it:

The parameter copy menu (S6.3) embodies four functions:

Parameter sets (S6.3.1)

The VACON parameter values and to store and load two customised parameter sets (all parameters included in the application).

On Parameter sets page (S6.3.1), push the Menu button right to enter the Edit menu. The text LoadFactDef begins to blink and you can confirm the loading of factory defaults by pushing the Enter button. The drive resets automatically.

Alternatively you can choose any other of the storing or loading functions with the Browser buttons. Confirm with the Enter button. Wait until 'OK' appears on the display.

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 Enter button. If you wish to keep the copy 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.

9.3.6.4 Parameter comparison

In the Parameter comparison submenu (S6.4), you can compare the actual parameter values to the values of your customised parameter sets and those loaded to the control keypad.

The comparison is performed by pushing the Menu button right when in the Compare parameters submenu. The actual parameter values are first compared to those of the customised parameter Set1. If no differences are detected a '0' is displayed on the lowermost line. But if any of the parameter values differ from those of the Set1 the number of the deviations is displayed together with symbol P (e.g. P1P5 = five deviating values). By pressing the Menu button right once again you can still enter the pages where you can see both the actual value and the value it was compared to. In this display, the value on the Description line (in the middle) is the default value and the one on the value line (lowermost) is the edited value. Furthermore, you can also edit the actual value with the Browser buttons in the edit mode that you can reach by pushing the Menu button right once again.

In the same way, you can perform the comparison of the actual values to Set2, Factory Settings and Keypad Set.

Default page (P6.6.1)

Here you can set the location (page) to which the display automatically moves as the Timeout time (see below) has expired or as the power is switched on to the keypad.

If the Default Page value is 0 the function is not activated, i.e. the last displayed page remains on the keypad display. Press the Menu button right once to enter the edit mode. Change the number of the Main menu with the Browser buttons. Pressing the Menu button right once again makes you able to edit the number of the submenu/page. If the page you want to move to by default is at the third level repeat the procedure. Confirm the new default page value with the Enter button. You can return to the previous step anytime by pushing the Menu button left.

Contrast adjustment (P6.6.4)

In case the display is unclear you can adjust its contrast through the same procedure as that for the timeout time setting (see above).

Backlight time (P6.6.5)

Giving a value for the Backlight time, you can determine how long the backlight stays on before going out. You can select here any time between 1 and 65535 minutes or 'Forever'. For the value setting procedure see Timeout time (P6.6.3).

9.3.6.7 Hardware settings

NOTE! The Hardware settings submenu is protected with a password (see Chapter Password (S6.5.1). 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 AC drive. 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)

With this function you can tell the AC drive, whether the internal brake resistor is connected or not. If you have ordered the AC drive 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 pushing the Menu button right. Use the Browser buttons to change the internal brake resistor status. Accept the change with the Enter button or return to the previous level with the 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.

Fan control (P6.7.2)

This function allows you to control the AC drive’s cooling fan. 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 heat sink temperature reaches 60°C or the converter is in RUN state. The fan receives a stop command when the heat sink temperature falls to 55°C and the converter is in STOP state. However, the fan runs for about a minute after receiving the stop command or switching on the power, as well as after changing the value from Continuous to Temperature.

NOTE! The fan runs always when the drive is in RUN state. Enter the edit mode by pushing the Menu button right. The present mode shown starts to blink. Use

the Browser buttons to change the fan mode. Accept the change with the Enter button or return to the previous level with the Menu button left.

HMI ACK timeout

11548_uk

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 AC drive 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 AC drive 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:

Example:

• Transfer delay between the AC drive and the PC = 600 ms

• The value of par. 6.7.3 is set to 1200 ms receiving delay)

• The corresponding setting shall be entered in the [Misc]-part of the file NCDrive.ini:

Retries = 5 AckTimeOut = 1200 TimeOut = 6000

(2 x 600, sending delay +

It must also be considered that intervals shorter than the AckTimeOut-time cannot be used in NCDrive monitoring.
