SAFETY

ONLY A COMPETENT ELECTRICIAN MAY CARRY OUT

THE ELECTRICAL INSTALLATION

1.1 Warnings

The components of the power unit of the frequency converter are live

when NXL is connected to mains potential. Coming into contact with

this voltage is extremely dangerous and may cause death or severe

injury. The control unit is isolated from the mains potential.

The motor terminals U, V, W (T1, T2, T3) and the DC-link/brake resistor

terminals –/+ (in NXL ≥1.1 kW) are live when NXL is connected to mains,

even if the motor is not running.

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

the relay outputs and other I/O-terminals may have a dangerous control

voltage present even when NXL is disconnected from mains.

WARNING

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 Honeywell can be used.

The heat sink of types MF2 and MF3 may be hot when the frequency

converter is in use. Coming into contact with the heat sink may cause

burns.

HOT SURFACE

1.2 Safety instructions

The Honeywell NXL frequency converter is meant for fixed installations

only.

Do not perform any measurements when the frequency converter is

connected to the mains.

After disconnecting the frequency converter from the mains, wait until the

fan stops and the indicators on the display go out. Wait 5 more minutes

before doing any work on NXL connections.

Do not perform any voltage withstand tests on any part of NXL. There is

a certain procedure according to which the tests shall be performed.

Ignoring this procedure may result in damaged product.

Prior to measurements on the motor or the motor cable, disconnect the

motor cable from the frequency converter.

Do not touch the IC-circuits on the circuit boards. Static voltage discharge

may damage the components.

1.3 Earthing and earth fault protection

The Honeywell NXL frequency converter must always be earthed with an earthing conductor

connected to the earthing terminal

The earth fault protection inside the frequency converter protects only the converter itself against

earth faults in the motor or the motor cable.

Due to the high capacitive currents present in the frequency converter, fault current protective

switches may not function properly. If fault current protective switches are used they must be tested

with the drive with earth fault currents that are possible to arise in fault situations.

1.4 Running the motor

Warning symbols

For your own safety, please pay special attention to the instructions marked with the following

symbols:

= Dangerous voltage

WARNING

= General warning

HOT SURFACE

= Hot surface – Risk of burn

MOTOR RUN CHECK LIST

Before starting the motor, check that the motor is mounted properly and

ensure that the machine connected to the motor allows the motor to be

started.

Set the maximum motor speed (frequency) according to the motor and

the machine connected to it.

Before reversing the motor shaft rotation direction make sure that this

can be done safely.

WARNING

Make sure that no power correction capacitors are connected to the

motor cable.

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

EU DIRECTIVE

2.1 CE marking

The CE marking on the product guarantees the free movement of the product within the EEA

(European Economic Area). It also guarantees that the product meets the various requirements

placed upon it (such as the EMC Directive and possibly other directives according to the so-called

new procedure).

NXL frequency converters carry the CE label as a proof of compliance with the Low Voltage

Directive (LVD) and the Electro Magnetic Compatibility (EMC). The company SGS FIMKO has acted

as the Competent Body.

2.2 EMC directive

2.2.1 General

The EMC Directive provides that the electrical apparatus must not excessively disturb the

environment they are used in, and, on the other hand, it shall have an adequate level of immunity

toward other disturbances from the same environment.

The compliance of NXL frequency converters with the EMC directive is verified with Technical

Construction Files (TCF) checked and approved by SGS FIMKO, which is a Competent Body.

2.2.2 Technical criteria

EMC compliance is a major consideration for NXL drives from the outset of the design. NXL

frequency converters are marketed throughout the world, a fact which makes the EMC requirements

of customers different. All NXL frequency converters are designed to fulfil even the strictest immunity

requirements.

2.2.3 NXL frequency converter EMC classification

NXL frequency converters are divided into two classes according to the level of electromagnetic

disturbances emitted. Later in this manual the division is made according to the mechanical sizes

(MF2, MF3, etc.). The technical data of the different sizes can be found in Chapter 0.

Class C (NXL HVAC IP54):

NXL HVAC drives with IP54 enclosure are delivered as class C products with an integrated RFI

filter. NXL HVAC drives IP54 selection fulfil the requirements of the product standard EN 61800-

3 (2004) category C1 (EN 55011 class B).

The emission levels correspond to the requirements of EN 61000-6-3.

Class N (NXL Compact):

No EMC emission protection. NXL Compact drives (frames MF2 and MF3) are delivered from the

factory without an integrated RFI filter as class N products. External RFI filters for these products for

class H are available.

Class H (NXL HVAC IP21):

NXL HVAC drives with IP21 enclosure are delivered as class H products with an integrated RFI

filter. NXL HVAC drives IP21 selection fulfil the requirements of the product standard EN 61800-

3 (2004) category C2 (EN 55011 class A).

The emission levels correspond to the requirements of EN 61000-6-4.

Class T:

The T-class converters have a small earth current and can be used with IT supplies only. If they are

used with other supplies no EMC requirements are complied with.

TECHNICAL DATA

4.1 Introduction

Honeywell NXL is a compact frequency converter with the output ranging from 250 W to 30 kW.

The Motor and Application Control Block is based on microprocessor software. The microprocessor

controls the motor basing on the information it receives through measurements, parameter settings,

control I/O and control keypad. The IGBT Inverter Bridge produces a symmetrical, 3-phase PWM-

modulated AC-voltage to the motor.

The control keypad constitutes a link between the user and the frequency converter. The control

keypad is used for parameter setting, reading status data and giving control commands. Instead of

the control keypad, also a PC can be used to control the frequency converter if connected through a

cable and a serial interface adapter (optional equipment).

You can have your Honeywell NXL drive equipped with control I/O boards NXLOPTAA, NXLOPTAI,

NXOPTB_ or NXOPTC_. Honeywell NXL HVAC series already includes I/O board NXLOPTAI as

standard.

All other sizes but MF2 have an internal brake chopper. For closer information, contact Honeywell

see back cover). The input EMC filters are available as options externally for MF2 and MF3. In other

sizes the filters are internal and included as standard.

6.1.3 Installation instructions

Before starting the installation, check that none of the components of the

frequency converter is live.

The NXL frequency converter types MF2 and MF3 shall be installed inside

switchgear, separate cubicle or electrical room because of the protection class

IP20 and the fact that the cable terminals are not protected.

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 30 m (MF2-MF3), 50 m

(MF4) and 300 m (MF5 – MF6)

The motor cables should cross other cables at an angle of 90 degrees.

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

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 >1MΩ.

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

Jumper selections on NXL basic board

The user is able to customise the functions of the frequency converter to better suit his needs by selecting

certain positions for the jumpers on the NXL board. The positions of the jumpers determine the signal type

of analogue input (terminal #2) and whether the termination resistor RS485 is used or not.

6.2.6 Motor thermistor (PTC) connection

There are three possibilities to connect a PTC resistor to NXL:

1. With optional board NXLOPTAI. (Recommended method. Board included in NXL HVAC as standard)

NXL equipped with NXLOPTAI fulfils IEC 664 if the motor thermistor

is insulated (= effective double insulation).

2. With optional board NXOPTB2.

NXL equipped with NXOPTB2 fulfils IEC 664 if the motor thermistor

is insulated (= effective double insulation).

3. With the digital input (DIN3) of NXL.

The DIN3 is galvanically connected to other I/O's of NXL.

This is why reinforced or double insulation of the thermistor (IEC 664) is absolutely required outside

the frequency converter (in the motor or between the motor and the frequency converter).

Note!

The NXL trips when PTC impedance exceeds 4,7 kΩ

It is strongly recommended to use NXLOPTAI or NXOPTB2 board for motor thermistor connection.

If the motor thermistor is connected to DIN3, the instructions above must be followed; otherwise a

serious safety hazard may result from the connection.

7.4.2 Parameter menu (P2)

Parameters are the way of conveying the commands of the user to the frequency converter. The

parameter values can be edited by entering the Parameter Menu from the Main Menu when the

location indication P2 is visible on the display. The value editing procedure is presented in Figure 7-

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. 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:

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.

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. not editable, when the drive is in RUN status. The frequency

converter must be stopped in order to edit these parameters.

The parameters values can also be locked using the function in menu S6 (see Chapter 7.4.7.2).

You can return to the Main menu anytime by pressing the Menu button left for 1—2 seconds.

The basic parameters are listed in Chapter 8.3. You will find the complete parameter lists and

descriptions in the HVAC and Multi-Control Application manuals.

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.

NOTE: The maximum difference between the output frequency and the keypad reference is 6 Hz.

The application software monitors the keypad frequency automatically.

See Figure 7-6 for how to edit the reference value (pressing the Enter button is not, however,

necessary).

7.4.3.3

Keypad direction

The keypad direction submenu displays and allows the operator to change the rotating direction of

the motor. This setting will not, however, influence the rotation direction of the motor unless

the keypad has been selected as the active control place.

See Figure 7-7 for how to change the rotation direction.

7.4.3.4

Stop button activation

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.

See Figure 7-7 for how to change the value of this parameter.

Fan control (P6.7.2)

Note! Only the higher power modules of MF3 have been equipped with a cooling fan, in lower power

modules of MF3 the cooling fan is available as optional equipment.

If the cooling fan has been installed in MF3 it runs continuously, when the power is switched on.

NXL HVAC:

This function allows you to control the frequency converter’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. The fan receives a stop command when the heat sink temperature falls to 55°C.

However the fan runs for about a minute after receiving the stop command, as well as after changing

the value from 0 (Continuous) to 1 (Temperature).

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.

Note! If the frequency converter 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 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:

Example

•

Transfer delay between the frequency converter 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

Retries = 5

[Misc]-part of the file NCDrive.ini:

AckTimeOut = 1200

TimeOut = 6000

It must also be considered that intervals that are shorter than the AckTimeOut-time cannot be used

in NC-Drive monitoring.

Modbus RTU protocol

Modbus RTU protocol is a simple but effective fieldbus protocol. Modbus network has a bus

topology, where every device has an individual address. With the help of the individual bus

addresses the commands are directed to the single devices within the network. Modbus supports

also broadcast -type messages, which are received by every device of the bus. Broadcast messages

are sent to the address ’0’ which is reserved for these messages.

The protocol includes CRC error detection and parity check for preventing the handling of messages

containing errors. In Modbus the data is transferred in hex mode asynchronically and a break of

approximately 3.5 characters is used as an end character. The length of the break depends on the

used baud rate.

Termination Resistor

The RS-485 bus is terminated with 120 Ω termination resistors in both ends. NXL has a built-in

termination resistor which is switched off as a default. See the jumper selections in chapter 6.2.5.1

7.4.8.3

Modbus address area

The Modbus bus of NXL uses the ID numbers of the application as addresses. The ID numbers can

be found in the parameter tables of the Application manual.

When several parameters/monitoring values are read at a time they must be consecutive. 11

addresses can be read and the addresses can be parameters or monitoring values.

7.4.8.4

Modbus process data

Process data is an address area for fieldbus control. Fieldbus control is active when the value of

Information about the status of the device and messages is indicated in the Status word. The Status

word is composed of 16 bits the meanings of which are described in the table below:

Actual speed

MSB

LSB

This is actual speed of the frequency converter. The scaling is –10000...10000. In the application,

the value is scaled in percentage of the frequency area between set minimum and maximum

frequency.

Control word

RST

DIR

RUN

In Honeywell applications, the three first bits of the control word are used to control the frequency

converter. However, you can customise the content of the control word for your own applications

because the control word is sent to the frequency converter as such.

Speed reference

MSB

LSB

This is the Reference 1 to the frequency converter. Used normally as Speed reference. The allowed

scaling is –10000...10000. In the application, the value is scaled in percentage of the frequency area

between the set minimum and maximum frequencies.

COMMISSIONING

8.1 Safety

Before commissioning, note the following directions and warnings:

Internal components and circuit boards of the frequency converter

(except for the galvanically isolated I/O terminals) are live when NXL 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 –/+

are live when NXL is connected to mains, even if the motor is not

running.

WARNING

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 NXL is disconnected from mains.

Do not make any connections with the frequency converter connected to

the mains.

After having disconnected 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 indicator through the keypad base). Wait 5 more

minutes before doing any work on NXL connections. Do not even open

the cover before this time has expired.

Before connecting the frequency converter to mains make sure that the

NXL front cover is closed.

The heat sink of types MF2 and MF3 may be hot when the frequency

converter is in use. Coming into contact with the heat sink may cause

burns.

HOT SURFACE

8.2 Commissioning of the frequency converter

Read carefully the safety instructions in Chapter 6 and above and follow them.

After the installation, make sure that:

- both the frequency converter and the motor are grounded.

- the mains and motor cables comply with the requirements given in Chapter 6.1.1.

- the control cables are located as far as possible from the power cables (see Chapter 6.1.3,

step 3); the shields of the shielded cables are connected to protective earth

may not touch the electrical components of the frequency converter.

. The wires

- For option boards only: make sure that the common ends of digital input groups are

connected to +24V or ground of the I/O terminal or the external supply.

Check the quality and quantity of cooling air (Chapter 5.2).

Check the inside of the frequency converter for condensation.

Check that all Start/Stop switches connected to the I/O terminals are in Stop-position.

Connect the frequency converter to mains.

Set the parameters of group 1 according to the requirements of your application. At least the

following parameters should be set:
