1. INTRODUCTION

This frequency controller is used with permanent magnet syn-

chronous motors (PM) or asynchronous motors (AC). Speed can

be controlled with a 0-10 V DC signal, potentiometer, Modbus RTU

or hand terminal. The hand terminal (PAN-08-0) is not automati-

cally included in the delivery but can be ordered as an accessory.

Main voltage requirement is 3-phase 400 VAC. Frequency control-

ler is equipped with an EMC ﬁlter.

Built-on means that the frequency controller is mounted at the

side of the fan. If the fan service side is on the other side, the

drive can easily be moved there by opening four screws. Cabling

between motor and drive is already done.

Built-on version is ready to be used and needs only power from

mains and control signals. They can be easily connected to the

terminals under the drive’s plastic cover.

2. FEATURES

As standard, frequency controller has the following built-in

features

• Modbus RTU

• 0-10 V analogue input for controlling speed

• Control via external hand terminal

• Indication relays for alarm and running

• Flying start

• Alarms for overload, over-voltage and under-voltage

• Motor and cable protector with built-in current limiter

• Short-circuit protection against phase to phase short circuiting

on motor output terminals

• Digital input for “Start/stop”

• Digital input for “Alarm reset” or “Fire mode”

• Built-in EMC ﬁlter

• Automatic speed reduction in the event of over temperature in-

side the drive or lacking phase on the supply input.

Frequency controller cooling ribs are in the air ﬂow. Surplus heat is removed

by active ventilation.

3. INSTALLATION

3.1. MECHANICAL INSTALLATION

The built-on frequency converter is factory mounted to left side of

the fan (when looking from behind of the fan). If needed, the fre-

quency converter can be removed to the right hand side of the fan

according to the following instructions. Otherwise please use the

cable tie (delivered with the fan) to attach the motor cable to the

motor bracket/mounting plate, see point 3.1.5.

3.1.2 Loosen the upper bolts and remove lower ﬁxing bolts (M6)

of the frequency converter mounting plate. You might need a

10 mm wrench with the upper front bolt.

3.1.3 Slide off the mounting plate.

3.1.4 Put the upper bolts (removed from the left hand side) on

their places on the right hand side of the motor bracket.

Bolts shall be loose enough to get the mounting plate slided

to its place. After that, attach lower bolts (also removed from

the left hand side) and tighten all bolts.

3.1.5 Attach the cable tie to motor bracket / mounting plate.

3.2. ELECTRICAL INSTALLATION

• Frequency converter must only be installed

and commissioned by trained and qualiﬁed

personnel.

• Incorrect electrical installation may cause risk

of severe or fatal personal injury.

• If natural draught through the duct system causes the fan to

rotate even when it has not received an operating signal, there

is a risk that the motor will induce voltage on the frequency

converter motor terminals, making them dangerous to touch.

3.2.1. SHORT CIRCUIT PROTECTION

• Correct short-circuit protection must always be used with the

frequency converter in accordance with local and international

regulations.

• Short-circuit protection is supplied by the installer

3.2.2. SUPPLEMENTARY PROTECTION

• Direct earthing or TN or TT system earthing can be used for

supplementary protection

• Frequency converter must always be supplementary protected

with an earthing wire connected to the protective earth terminal

(PE).

• If an RCD/HPFI (TT system) is used, it must be speciﬁcally in-

tended for use with motor controllers.

3.2.3. POTENTIAL EQUALISATION

• There is a risk of electrical interference if the ground potential

between the frequency converter and the air handling unit or

duct differ from each other. In the event of potential differences

between system components, an equalisation conductor must

always be ﬁtted.

• Recommended cable cross section is 10 mm

• Lugs should be used, and the equalisation conductor should be

attached to the frequency converter enclosure via one of the

screws used to mechanically install the unit.

3.2.4. EARTH CONNECTION (PE)

• Frequency converter must be earthed in accordance with appli-

cable local and international standards and directives.

• In power cable, please use an earthing lead which is suitable

for the purpose.

• Frequency converter must be earthed singly and must therefore

never be earthed in series.

• Keep earth connection wires as short as possible.

RELAY OUTPUTS

Relay output 1: Alarm

• Relay 1 (terminals 11, 12, 13) can be used to send an alarm

signal to an external device.

• The signal output is a changeover relay which is closed

between terminals 11 and 12 in idle position and otherwise

closes between terminals 12 and 13.

• If the frequency converter has stopped due to a critical alarm,

the relay will switch position and close between terminals 12

and 13. The relay is simultaneously opened between terminals

11 and 12.

• When the alarm is reset / acknowledged, the relay returns to

its original position, closing between terminals 11 and 12.

Relay output 2: Running indication

• Relay 2 (terminals 14, 15, 16) can be used to send an operating

signal to an external device.

• The signal output is a changeover relay which is closed

between terminals 14 and 15 in idle position and otherwise

closes between terminals 15 and 16.

• When the frequency converter receives a start signal, the relay

changes position, closing between terminals 15 and 16. The

relay is simultaneously opened between terminals 14 and 15.

• When the start signal to frequency convert is removed, the

relay returns to its starting position, closing between terminals

14 and 15.

3.2.11. HAND TERMINAL (PAN-08) CONNECTION AND FUNCTIONS

The FWD-02 frequency converter can be connected to a PAN-08

hand terminal via Modbus RJ12 connector ”A”.

If a PAN-08 is connected, the hand terminal will act as master

and the frequency converter as slave.

Only one master at a time can be connected to the RJ12 connec-

tors marked ”A” and ”B”.

It is thus not possible to connect both a hand terminal to connec-

tor ”A” and an active Modbus communication cable to connector

”B” at the same time.

PAN-08 has the following menu options:

• Status: Control and operating parameters for connected fre-

quency converter

• Setup: Setting application parameters

• Alarm: Read-out of alarm log for connected frequency converter

• Modbus: Changing Modbus settings for frequency converter

• About: Read-out of software version no. and type for connected

frequency converter

• Conﬁg: Changing frequency converter / motor settings.

4. FUNCTIONS

Frequency controller can be controlled via:

• Analogue/digital (A/D) inputs

• Modbus RTU

• Local hand terminal PAN-08-0

• Potentiometer

The factory setting is Analogue/digital (A/D) control

Frequency controller can be controlled by external input signals.

Before the frequency controller can be started, it must be given a

start/stop signal. It is given by short-circuiting terminals GND and

Din1.

Speed is controlled by connecting the control signal (0-10V DC) to

terminals 0-10V In and GND.

Relation between control signal (0-10 V In) and speed – see ﬁg.

4.2. MODBUS CONTROL

• Frequency converter can be controlled via Modbus commands

according to the Modbus protocol.

• Control of motor speed via Modbus communication is factory

disabled.

• If the fFrequency converter is to be controlled via Modbus, Coil

Stat Bit register 8 must be set to ”0” = ”Modbus control”.

• Other functions, such as alarm read-out and acknowledgement,

are still possible via Modbus even though “Modbus control” is

not activated.

• See more detailed description of Modbus in chapter 7. Modbus.

4.3. SWITCHING FREQUENCY

Switching frequency is crucial in determining the amount of audi-

ble acoustic noise emitted by the frequency converter.

The higher the switching frequency, the less audible noise will be

emitted by the frequency converter. At the same time, however,

internal losses will be increased, reducing efﬁciency.

The frequency converter can be set to operate constantly with a

switching frequency of either 4 kHz or 8 kHz, or it can be set to

change switching frequency automatically depending on motor

speed (AUTO setting).

Switching frequency (switching mode) is set via Modbus:

• Setting ”4kHz” = Constant 4kHz switching frequency

• Setting ”8kHz” = Constant 8kHz switching frequency

• Setting ”AUTO” = Switching frequency is changed automatically:

– At motor speeds higher than 70% of rated speed, switching

frequency is changed to 4 kHz

– At motor speeds lower than 60% of rated speed, switching

frequency is changed to 8 kHz

4.4. FIRE MODE

• Fire mode designates a function in which the frequency con-

verter is kept operating by an emergency program which disa-

bles the alarm monitor.

• Among other things, the function can be used in connection

with smoke extraction from a burning property. When ﬁre mode

is activated, an extraction fan will continue to remove smoke

from the property for as long as possible.

• In ﬁre mode, the frequency converter is able to maintain opera-

tion for at least an hour even when the frequency converter and

the fan motor are overheated (max. 70°C).

• In ﬁre mode, the overheating protection built into the frequency

converter is disabled and the motor is not stopped if communi-

cation is lost.

• In ﬁre mode, the fan is not stopped in case of faults or other

alarms from either the fan or the frequency converter.

• Speed is controlled to the actual setting, determined by an ex-

ternal 0-10V signal, a potentiometer or via Modbus from a Mod-

bus master controller.

• Fire mode can be activated via Modbus.

The control signal regulates motor speed between the set mini-

mum and maximum speeds (AC motor = Hz; PM motor = rpm)

5. BUILT-IN PROTECTION

• If the temperature inside frequency converter exceeds +95°C,

the frequency converter will attempt to reduce its internal heat

generation by reducing motor speed (rpm).

• Frequency converter has built-in current limitation for the pro-

tection of motor and cables and cannot therefore supply more

current than it is set to.

• In the event of lacking phase on the supply input, the frequency

converter will reduce speed and activate a non-critical alarm.

• The frequency converter motor output terminals are short cir-

cuit protected against phase-to-phase short circuiting.

6. ALARMS

• Frequency converter has a built-in alarm monitor, which moni-

tors optimal fault-free operation and triggers an alarm if operat-

ing or performance problems are observed.

• Alarms are either ”Critical” alarms or ”Non-critical” alarms.

• ”Critical” alarms stop the motor.

• ”Non-critical” alarms reduce motor performance.

• The built-in alarm monitor stops the frequency converter.

• If the alarm situation passes, the alarm is automatically reset

and frequency converter restarted.

• If the maximum number of restarts (5 times/60 min) is exceed-

ed, the alarm must be reset manually.

• The alarm can be reset by means of a Modbus command.

• The alarm is automatically reset if the power is disconnected

for longer than 60 seconds.

• Alarms can be read via Modbus, see Modbus protocol.

LED INDICATIONS

• Frequency converter is equipped with a two-colour LED which

indicates operating status.

• The LED is located on the underside of the frequency converter

beside the entry for the mains cable.

• LED lights constantly green when mains voltage is connected.

• LED ﬂashes green when Modbus communication is active.

• LED lights constantly red when at least one critical alarm is

active-

• LED ﬂashes red when at least one non-critical alarm is active.

7. MODBUS

7.1. INTRODUCTION

This protocol contains the Modbus addresses and registers which

are available in the frequency converter.

Modbus can access single addresses or several addresses

simultaneously, either by reading or writing 1-bit or 16-bit values.

A Modbus address contains either a 1-bit value or a 16-bit integer.

Values in this protocol are to be changed at your own risk.

It is your own responsibility that changing of values and settings

does not cause any overload or damage to the product, motor or fan.

8. MAINTENANCE

• Frequency converter is maintenance free under normal operat-

ing conditions and load proﬁles.

• The cooling ﬁns must be kept free of dust, dirt and other foreign

matter so that air can pass freely over them. Deposits of dust,

dirt or other foreign matter on and between the cooling ﬁns will

prevent cooling of the frequency converter and thus impair per-

formance.

• The cooling ﬁns may become very hot. (Max. +95°C under nor-

mal operating conditions)

• Frequency converter cannot be repaired on site. Never attempt

to repair a defective unit. Contact your supplier to obtain a re-

placement.

• Additional technical data are available on request from Fläkt-

Group.

9. TROUBLESHOOTING

• Before opening the frequency converter, the mains voltage

must be disconnected for at least 3 minutes to ensure there is

no risk of dangerous residual currents in electronic circuits or

capacitors.

• If natural draught through the duct system cause the fan to

rotate even though it has received no operating signal, there is

a risk that the motor will induce voltage on the frequency con-

verter motor terminals, making them dangerous to touch.

TROUBLESHOOTING WHEN FREQUENCY CONVERTER IS CONTROLLED VIA A/D SIGNALS:

Symptom Cause Action

Motor inoperative

Lacking supply voltage

Check voltage 400V in frequency controller terminals L1,

L2 and L3

Check whether short-circuit protection has been activated.

Check that the voltage supply to frequency converter has

not been cut off by other components.

Poor electrical connections Check electrical connections

Wrong motor for frequency converter setup Check that the correct motor settings have been read into

and stored in the frequency converter setup.

Lacking operating signal A/D control: Short-circuit frequency controller terminals

Din 1 (START) and GND

No 0-10 V DC control signal

Check that 0-10 VDC signal is connected correctly to fre-

quency controller terminals 0-10Vin and GND

With potentiometer control : Check that the potentiometer

is connected correctly to frequency controller terminals

+10V dc, 0-10V In and GND.

Active alarm Read out active alarms and remedy their cause.

The motor has been stopped by the built-in

motor protector 5 times because of overload

or other alarm.

Reset the alarm by short-circuiting frequency controller

terminals DIn 2 and GND.

The alarm can also be reset by disconnecting the power

supply to the frequency controller and reconnecting it after

approx. 60 seconds

Defective frequency controller

Replace frequency controller. Never attempt to repair a

defective frequency controller. Contact your supplier for

replacement/repair.

Defective motor Replace motor

Motor running in wrong direction Wrong phase sequence in motor cable Interchange two phase wires on the motor or the frequen-

cy converter terminal strip.

Motor is noisier than acceptable Switching frequency too low

Increase switching frequency

0 = Auto (factory setting), 1 = Low = 4 kHz, 2 = High = 8 kHz

Raising the switching frequency increases energy losses

in frequency controller. Switching frequency can be

changed using the Hand Terminal.

Frequency controller cuts out due

to an alarm.

At least one alarm active

Use Hand Terminal to view the alarm and determine which

alarm has stopped the controller/motor.

Reset the alarm by short-circuiting frequency controller

terminals DIn 2 and GND.

The alarm can also be reset by disconnecting the power

supply to the frequency controller and reconnecting it after

approx. 60 seconds.

The alarm is re-activated after reset

Use Hand Terminal or PC Tool to view the alarm and de-

termine which alarm has stopped the controller/motor.

Remedy the cause of repeated alarm activation.

Increase switching frequency.

0 = Auto

1 = Low = 4 kHz

2 = High = 8 kHz

Increasing switching frequency increases losses within

frequency converter, thus reducing efﬁciency.

Frequency converter switching frequency can be changed

via Hand Terminal or via Modbus.
