VLT®FCD Series
■High voltage warning
The voltage of the frequency converter
is dangerous whenever the converter
is connected to mains. Incorrect fitting
of the motor or frequency converter may cause
damage to the equipment, serious injury or death.
Consequently, it is essential to comply with the
instructions in this manual as well as local and
national rules and safety regulations.
■These rules concern your safety
1. The frequency converter must be disconnected from
the mains if repair work is to be carried out. Check
that the mains supply has been disconnected
and that the prescribed time has passed before
removing the inverter part from the installation.
2. The [STOP/RESET] key on the optional control
panel does not disconnect the equipment from
mains and is thus not to be used as a safety switch.
3. The unit must be properly connected to the
earth, the user must be protected against the
supply voltage and the motor must be protected
against overloading pursuant to prevailing
national and local regulations.
4. The earth leakage currents are higher than 3.5 mA.
5. Protection against motor overload is not included
in the factory setting. If this function is required,
set parameter 128 Motor thermal protection to
data value ETR trip or data value ETR warning.For
the North American market: The ETR functions
provide overload protection of the motor, class
20, in accordance with NEC.
■Warning against unintended start
1. The motor can be brought to a stop by
means of digital commands, bus commands,
references or a local stop, while the frequency
converter is connected to mains. If personal
safety considerations make it necessary to
ensure that no unintended start occurs, these
stop functions are not sufficient.
2. While parameters are being changed, the
motor may start. Consequently, the stop
key [STOP/RESET] on the optional control
panel must always be activated, following
which data can be modified.
3. A motor that has been stopped may start if faults
occur in the electronics of the frequency converter,
or if a temporary overload or a fault in the supply
mains or the motor connection ceases.
Warning:
It can be extremely dangerous to touch the electrical parts
even when the AC line supply has been disconnected.
For FCD 300: wait at least 4 minutes.

■The decentral concept
The FCD 300 Adjustable speed drive is designed
for decentral mounting, e.g. in the food and
beverage industry, in the automotive industry, or
for other material handling applications.
With the FCD 300 it is possible to utilize the cost saving
potential by placing the power electronics decentrally,
and thus make the central panels obsolete saving
cost, space and effort for installation and wiring.
VLT®FCD Series
2. Mounted directly onthe motor ("motor-mounted")
The unit is flexible in its mounting options for as
well stand alone mounting and motor mounting. It
is also possible to have the unit pre-mounted on
a Danfoss Bauer geared motor (3 in one solution).
Thebasicdesignwithaplugableelectronicpartand
a flexible and "spacious" wiring box is extremely
servicefriendly and easy to change electronics
without the need for unwiring.
The FCD 300 is a part of the VLT frequency converter
family, which means similar funcionality, programming,
and operating as the other family members.

■Control principle
A frequency converter rectifies AC voltage from
the mains supply into DC voltage, following which
it changes this voltage to an AC voltage with
variable amplitude and frequency.
The motor thus receives a variable voltage and
frequency, which enables infinitely variable speed
control of three-phase, standard AC motors.

■Mechanical installation
Please pay attention to the requirements
that apply to integration and remote
mounting. These must be complied
with to avoid serious injury or damage, especially
when installing large units.
The FCD 300 consists of two parts: The installation
part and the electronics part.
The two parts must be separated, and the installation
part is to be mounted first. After wiring, the electronics
is to be fixed to the installation part by the attached
6 screws. For compressing the gasket the screws
must be tightened with 2-2.4 Nm, tighten both centre
screws first, thereafter the 4 corner srews "cross over".
NB!:
Do not switch on the mains before the
6 screws are tightened.
The FCD 300 can be applied as following:
- Stand alone mounted close to the motor
- Motor mounted
or might be delivered pre mounted on a Danfoss
Bauer (geared) motor. Please contact the Danfoss
Bauer sales organisation for further information.
See Dimensional Drawings.
otor mounting
M
The installation box should be mounted on the
surface of the motor frame, typically instead of the
motor terminal box. The motor/geared motor may
be mounted with the shaft vertically or horizontally.
The unit mustnot be mounted upside down (the heat
sink pointing down). The cooling of the electronics is
independent on the motor cooling fan. For mounting
directly on Danfoss Bauer geared motors no adaption
plate is necessary. For motor mounting (non Danfoss
Bauer motors), an adaptor plate should usually be
applied. For that purpose a neutral plate incl gasket
and screws for attaching to the installation box is
available. The appropriate drillings and gasket for the
motor housing are applied locally. Please make sure,
that the mechanical strength of the mounting screws
and the threads are sufficient for the application. The
specified resistance against mechanical vibrations
does not cover the mounting onto a non Danfoss
Bauer motor, as the stability of the motor frame
and threads are outside Danfoss Drive’s control and
responsibility and the same applies to the enclosure
class. Please be aware, that the frequency converter
may not be used to lift the motor/geared motor.
The frequency converter is cooled by means of air
circulation. For the unit to be able to release its
cooling air, the minimum free distance above and
below the unit must be m
the unit from overheating, it must be ensured that the
ambient temperature does not rise above the max.
temperature stated for the frequency converter and
that the 24-hour average temperature is not exceeded.
The max. temperature and 24-hour average can
be seen in Ge neral technical data. If the ambient
temperature is higher, derating of the frequency
converter is to be carried out. See Derating for
ambient temperature. Pleasenotethattheservicelife
of the frequency converter will be reduced if derating
for ambient temperature is not considered.
tand alone mounting ("wall mounting")
S
For best cooling the unit should be mounted vertically,
however where space limitations require it, horizontal
mounting is allowable. The integrated 3 wall mounting
brackets in the wall mounting version can be used
for fixing the installation box to the mounting surface,
keeping a distance for possible cleaning between
the box and the mounting surface. Use the three
supplied washers to protect the paint.

1. Prepare the adaptor plate for mounting on the motor by
drilling the fixing holes and the hole for the cables.
2. Mount the plate on the motor with the normal terminal
box gasket.
3. Knock out the 4 screw holes for mounting the adaptor
plate (outer holes).
4. Mount the terminal box onto the motor by the 4 sealing
screws and the gasket supplied.
Use the supplied star washers for securing PE
connection according to EN 60204. The screws must
be tightened with 5 Nm.

■General information about electrical installation
■High voltage warning
The voltage of the frequency converter
is dangerous whenever the equipment is
connected to mains. Incorrect installation
of the motor or frequency converter may cause
damage to the equipment, serious injury or death.
Comply with the instructions in this manual, as well as
national and local rules and safety regulations.
Touching the electrical parts may be fatal - even after
the equipment has been disconnected from mains:
Wait at least 4 minutes for current dissipate.
NB!:
It is the responsibility of the user or installer
to ensure correct earthing and protection in
accordance with national and local standards.
■Cables
The control cable and the mains cable should be
installed separately from motor cables to prevent
noisetransfer. Asaruleadistanceof20cmis
sufficient, but it is recommended that the distance
is as great as possible, particularly when cables are
installed in parallel over large distances.
For sensitive signal cables such as telephone or data
cables the greatest possible distance is recommended.
Please note that the required distance depends on
installation and the sensitivity of the signal cables, and
that for this reason exact values cannot be given.
■Extra protection
ELCB relays, multiple protective earthing or earthing
can be used as extra protection, provided that local
safety regulations are complied with. In the case of an
earth fault, a DC content may develop in the faulty
current. Never use an RCD (ELCB relay), type A, as
it is not suitable for DC faulty currents. If ELCB relays
are used, local regulations must be complied with.
If ELCB relays are used, they must be:
- Suitable for protecting equipment with a DC content
in the faulty current (3-phase bridge rectifier)
- Suitable for a pulse-shaped, brief discharge
on power-up
- Suitable for a high leakage current.
See also RCD Application Note MN.90.GX.02.
■High voltage test
A high voltage test can be performed by
short-circuitingterminalsU,V,W,L1,L2andL3,
and applying max. 2160 V DC in 1 sec. between
this short-circuit and PE-terminal.
■Electronics purchased without installation box
If the electronic part is purchased without the
Danfoss installation part, the earth connection
the
must be suitable for high leakage current. Use
of original Danfoss installation box or installation
kit 175N2207 is recommended.
When being placed in cable trays, sensitive cables
may not be placed in the same cable tray as t
motor cable. If signal cables run across power
cables, this is done at an angle of 90 degrees.
Remember that all noise-filled inlet
to a cabinet must be screened/armoured.
See also EMC-compliant electrical installation.
Cable glands
It must be assured that appropriat
glands needed for the environment are chosen
and carefully mounted.
■Screened/armoured cables
The screen must have low HF impe
achieved by a braided screen of copper, aluminium or
iron. Screen reinforcement intended for mechanical
protection, for example, is
installation. See also Use of EMC-correct cables.

VLT®FCD Series
NB!:
Do not plug/unplug the electronic part with
mains voltage switched on.
■Protective earth
The earth connection serves several purposes.
• Safety earth (Protective earth, PE)
The equipment must be properly earthed according
to local regulation. This equipment has a leakage
current > 3.5 mA AC. It must be connected to
an earth connection complying with the local
rules for high leakage current equipment.
Typically, this implies that the PE conductors
must be mechanically enhanced (minimum cross
2
section 10 mm
) or duplicated
• Noise "clamping" (high frequencies)
Stable communication between units call for
screening of the communication cables (1).
Cables must be properly attached to screen
clamps provided for that purpose.
• Equalisation of voltage potential (low frequencies)
To reduce alignment currents in the screen
of the communication cable, always apply a
short earthing cable between units that are
connected to the same communication cable (2)
or connect to an earthed frame (3).
• Potential equalization: All metal parts, where the
motors are fastened, must be potential equalized
PE connections, voltage equalising cables and the
screen of the communication cable should be
connected to the same potential (4).
Keep the conductor as short as possible and use
the greatest possible surface area.
The numbering refers to the figure.
Installation
Proper installation earthing
■EMC-correct electrical installation
General points to be observed to ensure
EMC-correct electrical installation.
- Use only screened/armoured motor cables and
screened/armoured control cables.
- Connect the screen to earth at both ends.
MG.04.B7.02 - VLT is a registered Danfoss trademark
- Avoid installation with twisted screen ends (pigtails),
since this ruins the screening effect at high
frequencies. Use cable clamps instead.
-Don’t remove the cable screen between the
cable clamp and the terminal.
11
■ATEX correct installation
The following issues must be taken into account when
installing the FCD 300 in ATEX zone 22 environments:
• Motor must be designed, tested and certified by the
motor manufacturer for variable speed application
• Motor must be designed for Zone 22 operation.
I.e. with type of protection "tD" acc. to
EN61241-0 and -1 or EN50281-1-1.
• Motor must be provided with thermistor protection.
The thermistor protection must either be connected
to an external thermistor relay, with EC Type
Examination Certificate or compatible with
the FCD 300 thermistor input.
If the FCD 300 thermistor protection is used,
the thermistor must be wired to terminals
31a and 31b, and thermistor trip activated by
programming parameter 128 to thermistor trip
[2]. See parameter 128 for further details.
• Cable entries must be chosen for the enclosure
protection to be maintained. It must also be
ensured that the cable entries comply with the
requirements for clamping force and mechanical
strengths as described in EN 50014:2000.
• The FCD must be installed with appropriate earth
connecting according to local/national regulations.
• The installation, inspection and maintenance of
electrical apparatus for use in combustible dusts,
must only be carried out by personnel that is
trained and familiar with the concept of protection.

■Parallel connection of motors
The frequency converter is able to control several
motors connected in parallel. If the motors are
to have different rpm values, use motors with
different rated rpm values. Motor rpm is changed
simultaneously, which means that the ratio between
the rated rpm values is maintained across the range.
The total current consumption of the motors is
not to exceed the maximum rated output current
for the frequency converter.
I
INV
Problems may arise at the start and at low rpm
values if the motor sizes are widely different. This
is because the small motors’ relatively high ohmic
resistance in the stator calls for a higher voltage
at the start and at low rpm values.
converter cannot be used as motor protection for
the individual motor. For this reason further motor
protection must be used, e.g. thermistors in each
motor (or an individual thermal relay).
NB!:
Parameter 107 Automatic motor tuning, AMT
cannot be used when motors are connected
in parallel. Parameter 101 Torque characteristic
must be set to Special motor characteristics [8]
when motors are connected in parallel.
■Motor cables
See Technical data for correct dimensioning of motor
cable cross-section and length. Always comply with
national and local regulations on cable cross-section.
NB!:
If an unscreened/unarmoured cable is used,
some EMC requirements are not complied with,
see EMC test results in the Design Guide.
If the EMC specifications regarding emission are
to be complied with, the motor cable must be
screened/armoured, unless otherwise stated for the
RFI filter in question. It is important to keep the motor
cable as short as possible so as to reduce the noise
level and leakage currents to a minimum. The motor
cable screen must be connected to the metal cabinet
of the frequency converter and to the metal cabinet of
the motor. The screen connections are to be made
with the biggest possible surface area (cable clamp).
This is enabled by different installation devices in
different frequency converters. Mounting with twisted
screen ends (pigtails) is to be avoided, since these
spoil the screening effect at high frequencies. If it
is necessary to break the screen to install a motor
isolator or motor relay, the screen must be continued
at the lowest possible HF impedance.

In lifting/lowering applications you need to be able
to control an electromagnetic brake. The brake
is controlled using the special mechanical brake
control/supply terminals 122/123.
When the output frequency exceeds the brake cut
out value set in par. 138, the brake is released if the
motor current exceeds the preset value in parameter
140. When stopping the brake is engaged when
the output frequency is less than the brake engaging
frequency, which is set in par. 139.
If the frequency converter is at alarm status

■Electrical installation, control cables
Control cables must be screened/armoured. The
screen must be connected to the frequency converter
chassis by means of a clamp. Normally, the screen
must also be connected to the chassis of the
controlling unit (use the instructions for the unit in
question). In connection with very long control cables
and analogue signals, in rare cases depending on
the installation, 50/60 Hz earth loops may occur
because of noise transmitted from mains supply
cables. In this connection, it may be necessary
to break the screen and possibly insert a 100 nF
capacitor between the screen and the chassis.

■Parameter Setup
A frequency converter’s comprehensive work area can
be accessed via a large number of parameters, making
it possible to adapt its functionality for a specific
application. To provide a better overview of the many
parameters, there is a choice of two programming
modes - Menu mode and Quick Menu mode. The
former provides access to all parameters. The latter
takes the user through the parameters, which make
it possible to start operating the frequency converter
in most cases, in accordance with the Setup made.
Regardless of the mode of programming, a change
of a parameter will take effect and be visible both in
the Menu mode and in the Quick menu mode.
Structure for Quick menu m ode v Menu mode
In addition to having a name, each parameter is linked
up with a number which is the same regardless of
the programming mode. In Menu mode, paramet
will be split into groups, with the first digit (left)
of the parameter number indicating the group
number of the parameter in question.
