Introduction to FCD 300
VLT®FCD Series
■ General warning
The voltage of the frequency converter is
d
angerous whenever the converter is con-
n
ected to mains. Incorrect fitting of the
m
otor 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
s
afety 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.
195NA194.10
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.

■ Technology
■ 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.
1. Mains voltage
3 x 380 - 480 V AC, 50 / 60 Hz.
2
. Rectifier
Three-phase rectifier bridge which rectifies AC voltage into DC voltage.
3
. Intermediate circuit

√2 x mains voltage [V].
4
. Intermediate circuit coils

Variable frequency: 0.2 - 132 / 1 - 1000 Hz.
8
. Control card
Here is the computer that controls the inverter which
generates the pulse pattern by which the DC voltage
is converted into variable AC voltage with a variable
frequency.
■ 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.
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). The basic
design with a plugable electronic part and 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.
■ Cleaning
The enclosure (IP66/NEMA type 4x indoor) will offer
protection against dirt and water ingress, and is designed suitable for cleaning as performed in food and
beverage plants with the concentrations of cleaning
solvent as recommended by the manufacturer. High
pressure cleaning in very short distance or long time
with hot water may damage gaskets and lables.
■ FCD 300 control principle
A frequency converter is an electronic unit which is
able to infinitely variably control the rpm of an AC
motor. The frequency converter governs the motor
speed by converting the regular voltage and frequency from mains, e.g. 400 V / 50 Hz, into variable
magnitudes. Today the frequency converter controlled AC motor is a natural part of all types of
automated plants.
The FCD 300 Series has an inverter control system
called VVC (Voltage Vector Control). VVC controls
an induction motor by energizing with a variable frequency and a voltage suitable for it. If the motor load
changes, so does its energizing and speed. That is
why the motor current is measured on an ongoing
MG.04.A1.02 - VLT is a registered Danfoss trade mark
5
Introduction to FCD 300
VLT®FCD Series
basis, and a motor model is used to calculate the
actual voltage requirement and slip of the motor.
■ Programmable inputs and outputs in four Setups
In the FCD 300 Series it is possible to program the
different control inputs and signal outputs and to select four different user-defined Setups for most
parameters. It is easy for the user to program the required functions on the control panel or via serial
communication.
■ Mains protection
The FCD 300 Series is protected against the transients that may occur on the mains, such as
coupling with a phase compensation system or transients from fuses blown or when lightening strikes.
Rated motor voltage and full torque can be maintained down to approx. 10% undervoltage in the
mains supply.
As all 400 V units in the FCD 300 Series have intermediate circuit coils, there is only a low amount of
harmonic mains supply interference. This gives a
good power factor (lower peak current), which reduces the load on the mains installation.
■ Frequency converter protection
The current measurement in the intermediate circuit
constitutes perfect protection of the FCD 300 Series
in case there is a short-circuit or an earth fault on
the motor connection.
Constant monitoring of the intermediate circuit current allows switching on the motor output, e.g. by
means of a contactor.
Efficient monitoring of the mains supply means that
the unit will stop in the case of a phase drop-out (if
the load exceeds approx. 50%). In this way, the inverter and the capacitors in the intermediate circuit
are not overloaded, which would dramatically reduce
the service life of the frequency converter.
The FCD 300 Series offers temperature protection
as standard. If there is a thermal overload, this function cuts out the inverter.
■ Reliable galvanic isolation
In the FCD 300 all digital inputs/outputs, analogue
inputs/outputs and the terminals for serial communication are supplied from or in connection with
circuits that comply with PELV requirements. PELV
is also complied with in relation to relay terminals at
max. 250 V, so that they can be connected to the
mains potential.
See section Galvanic Isolation (PELV) for further details.
■ Advanced motor protection
The FCD 300 Series has integral electronic motor
protection.
The frequency converter calculates the motor temperature on the basis of current, frequency and time.
As opposed to traditional, bimetallic protection, electronic protection takes account of reduced cooling at
low frequencies because of reduced fan speed (motors with internal fan). This function cannot protect
the individual motors when motors are connected in
parallel. Thermal motor protection can be compared
to a protective motor switch, CTI.
To give the motor maximum protection against overheating when it is covered or blocked, or if the fan
should fail, you can install a thermistor and connect it
to the frequency converter’s thermistor input (Digital
input), see parameter 128 Thermal motor protection.
NB!:
This function cannot protect the individual
motors in the case of motors linked in parallel.

■ CE labelling
What is CE labelling?
The purpose of CE labelling is to avoid technical obstacles to trade within EFTA and the EU. The EU has
introduced the CE label as a simple way of showing
whether a product complies with the relevant EU directives. The CE label says nothing about the
specifications or quality of the product. Frequency
converters are regulated by three EU directives:
The machinery directive (98/37/EEC)
All machines with critical moving parts are covered
by the machinery directive, which came into force on
1 January 1995. Since a frequency converter is
largely electrical, it does not fall under the machinery
directive. However, if a frequency converter is supplied for use in a machine, we provide information on
safety aspects relating to the frequency converter.
We do this by means of a manufacturer’s declaration.
The low-voltage directive (73/23/EEC)
Frequency converters must be CE labelled in accordance with the low-voltage directive, which came
into force on 1 January 1997. The directive applies
to all electrical equipment and appliances used in
the 50 - 1000 Volt AC and the 75 - 1500 Volt DC
voltage ranges. Danfoss CE labels in accordance
with the directive and issues a declaration of conformity upon request.
The EMC directive (89/336/EEC)
EMC is short for electromagnetic compatibility. The
presence of electromagnetic compatibility means
that the mutual interference between different components/appliances is so small that the functioning of
the appliances is not affected.
The EMC directive came into force on 1 January
1996. Danfoss CE labels in accordance with the directive and issues a declaration of conformity upon
request. In order that EMC-correct installation can
be carried out, this manual gives detailed instructions for installation. In addition, we specify the
standards which our different products comply with.
We offer the filters that can be seen from the specifications and provide other types of assistance to
ensure the optimum EMC result.
In the great majority of cases, the frequency converter is used by professionals of the trade as a
complex component forming part of a larger appliance, system or installation. It must be noted that the
responsibility for the final EMC properties of the appliance, system or installation rests with the installer.

■ Enclosure
All FCD 300 units are supplied with IP 66, NEMA 4x
(Indoor) enclosure as standard.
■ Brake
FCD 300 is available with or without an integral
brake module. See also the section entitled Brake
resistors for ordering a brake resistor.
Including mechanical brake control/supply.
■ 24 V external supply
Back up of control supply with 24 V DC is available
as optional function.
■ RFI filter
FCD 300 has an integral 1A RFI-filter. The integral
1A RFI filter complies with EMC standards EN
55011-1A. See the sections Cable lengths and
Cross section for further details.
■ Harmonic filter
The harmonic currents do not affect power consumption directly, but they increase the heat losses
in the installation (transformer, cables). That is why
in a system with a relatively high percentage of rectifier load it is important to keep the harmonic currents
at a low level so as to avoid a transformer overload
and high cable temperature. For the purpose of ensuring low harmonic currents, the units are fitted with
coils in their intermediate circuit as standard. This
reduces the input current I
RMS
by typically 40 %.
■ Display unit
On the FCD 300 unit there are 5 indicator lamps for
voltage (ON), warning, alarm, status and bus.
In addition, an LCP control panel to be connected
via a plug to the frequency converter is available as
an option. The LCP control panel can be installed
up to 3 metres away from the frequency converter,
e.g. on a front panel, by means of a mounting kit.
All displays of data are via a 4-line alpha-numerical
display, which in normal operation is able to show 4
operating data items and 3 operation modes continu-

VLT®FCD Series
ously. During programming, all the information
required for quick, efficient parameter Setup of the
frequency converter is displayed. As a supplement
to the display, the LCP has three indicator lamps for
voltage (ON), warning (WARNING) and alarm
(ALARM). Most of the frequency converter’s parameter Setups can be changed immediately via the LCP
control panel. See also the section entitled The LCP
control unit in the Design Guide.
■ Fieldbus protocols
Danfoss frequency converters are able to fulfill many
different functions in a process control system. The
frequency converter can be integrated directly in an
overall surveillance system, which will allow detailed
process data to be transferred via serial communication.
The protocols listed below are based on an RS 485
bus system with a maximum transmission speed of
9600 baud. The following telegram profiles are supported as standard:
- FC protocol, which is a profile adapted to Dan-
foss.
- Profidrive protocol, which supports the profidrive
profile
See Serial communication for FCD 300 for further
details of telegram profiles.
■ Fieldbus option
The increasing information requirements in industry
make it necessary to collect or visualize many different process data. Important process data help the
system technician with the daily monitoring of the
system. The large amounts of data involved in major
systems make a higher transmission speed than
9600 baud desirable.
Profibus is a fieldbus system, which can be used for
linking automation devices such as sensors and
actuators with the controls by means of a twoconductor cable.
Profibus DP is a very fast communication protocol,
made specially for communication between the automation system and various types of equipment.
Danfoss FCD 300 can be supplied with the Profibus
®
DP in a 3 mbit and a 12 mbit version. Units with
Profibus protocol can either be controlled by FC protocol or Profidrive protocol.
Profibus is a registered trade mark.

■ PC software and serial communication
Danfoss offers various options for serial communication. Using serial communication, it is possible to
monitor, program and control one or several frequency converters from a centrally located computer.
In addition, all FCD 300 units have an RS 485 port
as standard, thereby enabling communication e.g.
with a PC. For this purpose, a program called VLT
Software Dialog is available.
VLT Software Dialog comes in three modules, as a
minimum containing the programs of the Basic module.
The Basic module covers:
TEST RUN used for controlling and running in a frequency converter, including
- Setting of reference value.
- simultaneous showing of selected parameters in
the form of graphs.
- option of DDE link, e.g. to spreadsheet.
PARAMETER SETUP is used for setting up and
transmitting parameter sets, including:
- setting of frequency converter parameters.
- parameter sets can be collected from and copied
to a frequency converter.
- documentation / setup print incl. charts.
HISTORY where the different development stages of
VLT Software dialog can be studied.
BUS ADDRESS SETUP is used for addressing FCD
300.
The logging module covers:
LOGGING is used for collecting and displaying historical or real-time operating data.
- presentation of selected parameters from several
frequency converters in the form of graphs.
- collection of log data for file.
- option of DDE link, e.g. to spreadsheet.
MODEM SETUP is used to set up the frequency converter’s modem. The module sets up the frequency
converter’s modem via the PC’s communication port.
The template module covers:
TEMPLATE SETUP is used for setting up template
files for PARAMETER SETUP.
- the template file acts as a screen that limits the
number of accessible parameters when a parameter file is to be made or edited in PARAMETER
SETUP
- the template file may contain preset values for
the parameters of the frequency converter
NB!:
The Logging and Template modules call for
the Basic module to be installed on the same
PC.

■ Dynamic braking
With the FCD 300 the dynamic braking quality in an
application can be improved in two ways, either with
the aid of brake resistors or AC braking.
Danfoss offers a complete range of brake resistors
for all FCD 300 frequency converters.
It is the job of the brake resistor to apply a load to
the intermediate circuit during braking, thereby ensuring that the brake power can be absorbed by the
brake resistor.
Without a brake resistor, the intermediate circuit voltage of the frequency converter would go on rising,
until cutting out for protection. The advantage of using a brake resistor is that you can brake quickly with
large loads, e.g. on a conveyor belt.
Danfoss has chosen a solution in which the brake
resistor is not integrated into the frequency converter. This gives the user the following advantages:
- The resistor’s cycle time can be selected as required.
- The heat generated during braking can be
diverted outside the panel cabinet, where the energy can possibly be utilised.
- No overheating of the electronic components,
even if the brake resistor is overloaded.
An internal brake resistorcan be mounted on the
small brake duty cycles.
AC braking is an integrated function that is used for
applications in which there is a need for limited dynamic braking. The AC braking function makes it
possible to reduce the brake power in the motor instead of in a brake resistor. The function is intended
for applications where the required braking torque is
less than 50% of rated torque. AC braking is selected in par. 400 Brake function.
NB!:
The AC brake cannot be used if the required
braking torque is more than 50% of rated
braking torque. In such instances a brake resistor
must be used.
■ Brake Setup
The figure shows a brake Setup with a frequency
converter.
In the following paragraphs, expressions and
acronyms are used about brake Setups that can be
seen from the figure.
■ Calculation of brake resistance
To ensure that the frequency converter does not cut
out for safety reasons when the motor brakes, the
resistance value is selected on the basis of the peak
braking effect and the intermediate circuit voltage:
Rbr=
U
DC
2
P
peak
[]
It can be seen that the brake resistance depends on
the intermediate circuit voltage (UDC).
With frequency converters that have a mains voltage
of 3 x 380 - 480 Volt, the brake will be active at 770
Volt (UDC).
You can also choose to use the brake resistance
recommended by Danfoss (R
REC
). This is a guarantee that the frequency converter is able to brake at
the highest braking torque (M
BR
). The recommended
brake resistance can be seen from the ordering table
for brake resistors.

NB!:
The minimum brake resistance selected
should have an ohmic value no more than
10% lower than that recommended by Danfoss. I
f a
l
ower brake resistance is selected there is a risk of
o
vercurrent, which can destroy the unit.
■ Calculation of braking power
When calculating the braking power, it must be
ensured that the mean and peak powers can be dissipated to the brake resistor. The mean power is
determined by the period time of the process, i.e. for
how long the brake is applied in relation to the
period time of the process. The peak power is determined by the braking torque, which means that
during braking the brake resistor must be able to
dissipate the energy input. The figure shows the relation between mean power and peak power.
■ Calculation of peak power of brake resistor
P
PEAK, MEC
is the peak power at which the motor
brakes on the motor shaft. It is calculated as follows:
P
P E AK;MEC
=
P
MOTOR
2MBR

100
[W]
P
peak
is the term describing the braking power that is
applied to the brake resistor when the motor applies
the brakes. P
PEAK
is smaller than P
PEAK, MEC
, as the
power is reduced by the efficiency of the motor and
the frequency converter. The peak effect is calculated as follows:
P
PEAK
=
P

[W]
If you select Danfoss’ recommended braking resistor
(R
REC
), you are certain that the braking resistance
can generate a braking torque of 160% on the motor
shaft.
■ Calculation of mean power on brake resistor
The mean power is determined by the period of the
process, i.e. how long you brake in relation to the
period of the process.
Duty-cycle for braking is calculated as follows:
Duty0cycle
=
T
b
2
100
T
p
[%]
T
p
= The process time in seconds.
T
b
= The braking time in seconds.
Danfoss sells brake resistors with variable dutycycles up to 40%. For example, with a 10%
duty-cycle, brake resistors can take up P
peak
in 10%
of the process period. The remaining 90% of the period time is spent on redirecting surplus heat.
The mean power at 10% duty cycle can be calculated as follows:
P
avg
=
P
peak
10
[W]
The mean power at 40% duty cycle can be calculated as follows:
P
avg
=
P
peak
2:5
[W]
These calculations apply to intermittent braking with
period times of up to 120 seconds.
NB!:
Period times longer than 120
sec. may lead to overheating of the resistor.
■ Continuous braking
For continuous braking, a brake resistor should be
selected in which the constant braking power does
not exceed the mean power P
AVG
of the brake resistor.
Please contact your Danfoss supplier for further information.

■ Optimal braking using resistor
Dynamic braking is useful from maximum speed
down to around 8% of rated speed. Below 8%
speed DC braking can be used if necessary.
The most effective method is to switch from dynamic
to DC braking.
■ Brake cable
Max. length [m]: 10 m
The connection cable to the brake resistor must be
screened/armoured. Connect the screen to the conductive backplate at the frequency converter and to
the brake resistor metal cabinet by means of cable
clamps.
NB!:
If Danfoss brake resistors are not used,
it must be ensured that induction for the brake
resistor is low.

■ Safety functions in connection with installation
When a brake resistor is installed, the best possible
endeavours should be made to avoid overloads, as
the heat generating from a brake resistor may involve a fire risk.
NB!:
The brake resistor
should be fitted to a nonflammable material.
For protection of the installation, a thermal relay is
fitted that cuts out the frequency converter if the
brake current is too high. Danfoss’ 40% brake resis-
tors contain a KLIXON switch. Flat pack resistors
are self-protecting.
The brake current setting on the thermal relay is calculated as follows:

■ The LCP 2 control unit, option
The FCD 300 can be combined with an LCP control
unit (Local Control Panel - LCP 2) which makes up a
complete interface for operation and programming of
the frequency converter. The LCP 2 control unit can
be attached up to three metres from the frequency
converter, e.g. on a front panel, using an accessory
kit.
The control panel is divided into five functional
groups:
1. Display.
2. Keys used to change the display function.
3. Keys used to change the programme parameters.
4. Indicator lamps.
5. Local control keys.
All data is displayed via a 4-line alphanumeric display, which during normal operation will be able to
continuously display 4 items of operating data and 3
operating modes. During programming all information needed for quick, effective parameter setup of
the frequency converter will be displayed. As a supplement to the display, there are three indicator
lamps for voltage (ON), warning (WARNING) and
alarm (ALARM). All frequency converter parameter
Setups can be changed immediately from the control
panel, unless this function has been programmed as
Locked [1] via parameter 018 Lock for data changes.
■ Control keys for parameter Setup
The control keys are divided into functions, in such a
way that the keys between the display and the indicator lamps are used for parameter Setup, including
selection of the display’s view mode during normal
operation.
[DISPLAY/STATUS] is used to select the display’s
view mode or to change back to Display mode from
either Quick Menu or Menu mode.
[QUICK MENU] provides access to the parameters
used in the Quick Menu. It is possible to switch between Quick Menu and Menu mode.
[MENU] gives access to all parameters. It is possible to switch between Menu mode and Quick Menu.
[CHANGE DATA] is used to change a parameter
that has been selected either in Menu mode or
Quick Menu.
[CANCEL] is used if a change to the selected parameter is not to be implemented.
[OK] is used to confirm a change to a selected pa-
rameter.
[+ / -] are used for selecting parameters and for
changing parameter values.
These keys are also used in Display mode to switch
between the readouts of operating variables.
[< >] are used for selecting parameter group and to
move the cursor when changing a numerical value.

■ Indicator lamps
At the bottom of the control panel are a red alarm
lamp, a yellow warning lamp and a green voltage indicator lamp.
If certain threshold values are exceeded, the alarm
and/or warning lamp are activated, while a status or
alarm text is shown on the display.
NB!:
The voltage indicator lamp is activated when
voltage is connected to the frequency con-
verter.
■ Local control
[STOP/RESET] is used for stopping the motor con-
nected or for resetting the frequency converter after
a drop-out (trip). Can be set to active or inactive via
parameter 014 Local stop.
If stop is activated Display line 2 will flash.
NB!:
If an external stop function is not selected and
the [STOP/RESET] key is set to inactive, the
motor can only be stopped by disconnecting the voltage to the motor or the frequency converter.
[JOG] changes the output frequency to a preset frequency while the key is held down. Can be set to
active or inactive via parameter 015 Local jog.
[FWD / REV] changes the direction of rotation of the
motor, which is indicated by means of the arrow on
the display. Can be set to active or inactive via parameter 016 Local reversing. The [FWD/REV] key is
only active when parameter 002 Local/remote opera-
tion is set to Local control.
[START] is used to start the frequency converter. Is
always active, but cannot override a stop command.
NB!:
If the local control keys are set to inactive,
these will both become active when the frequency converter is set to Local control and Remote
control via parameter 002 Local/remote operation,
with the exception of [FWD/REV], which is only active in Local control.

■ 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 mode 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,
parameters will be split into groups, with the first

■ Mechanical installation
Please pay attention to the requirements
t
hat apply to integration and remote
m
ounting. These must be complied with
t
o avoid serious injury or damage, especially when
installing large units.
The FCD 300 is consists of two parts: The installation part and the 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 3 Nm.
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.
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
inimum 100 mm. To protect 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
General technical data. If the ambient temperature is higher, derating of the frequency
converter is to be carried out. See Derating for am-
bient temperature. Please note that the service life
of the frequency converter will be reduced if derating
for ambient temperature is not considered.
S
tand alone mounting ("wall mounting")
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.
M
otor mounting
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 in-
dependent on the motor cooling fan. 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.
Please be aware, that the frequency converter may
not be used to lift the motor/geared motor.

■ General information about electrical installation
■ High voltage warning
The voltage of the frequency converter
i
s dangerous whenever the equipment is
connected to mains.Incorrect fitting of the
motor or frequency converter may cause damage to
the equipment, serious injury or death. Consequently, the instructions in this manual, as well as
national and local rules and safety regulations must
b
e complied with.
Touching the electrical parts may be fatal
- even after the equipment has been disconnected
f
rom mains: Wait at least 4 minutes.
NB!:
It is the user’sorfitter’s responsibility to
ensure correct earthing and protection in ac-
cordance with national and local standards.
■ Earthing
The following basic points must be considered at installation:
• Safety earthing: Please note that the frequency
converter has a high leakage current and must
be earthed appropriately for safety reasons. Apply local safety regulations.
• High frequency earthing: Keep earthing cables as
short as possible.
Connect the different earthing systems, thereby ensuring the lowest possible conductor impedance.
The lowest possible conductor impedance is
achieved by keeping the conductor as short as possible and by using the greatest possible surface
area. A flat conductor, for example, has a lower HFimpedance than a round conductor, calculated for
the same conductor cross-section C
VESS
. If several
units are installed on a common metal structure, it
should be used as a joint earth reference plate. The
metal cabinets of the different units must be fitted to
the metal structure at the lowest possible HFimpedance. With this feature, different HF-voltages
will not arise in different units, and there will be no
noise currents in cables used to connect units.
Noise radiation will be reduced. In order to achieve
a low HF-impedance, the fastening bolts of the units
can be used as HF-connection to the metal structure. It is necessary to remove any layers of isolating
paint or similar from the attachment points.
■ Cables
The control cable and the mains cable should be installed separately from motor cables to prevent noise
transfer. As a rule a distance of 20 cm is 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 the installation and the sensitivity of the
signal cables, and that for this reason exact values
cannot be given.
When being placed in cable trenches, sensitive cables may not be placed in the same cable trench as
the motor cable. If signal cables run across power
cables, this is done at an angle of 90 degrees. Remember that all noise-filled inlet and outlet cables to
a cabinet must be screened/armoured.
See also
EMC-compliant electrical installation.
■ Screened/armoured cables
The screen must have low HF impedance, which is
achieved by a braided screen of copper, aluminium
or iron. Screen reinforcement intended for mechanical protection, for example, is not suitable for
EMC-correct installation.
See also Use of EMC-correct cables.
■ 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.
■ High voltage test
A high voltage test can be performed by shortcircuiting terminals U, V, W, L1, L2 and L3, and

■ EMC-correctelectrical installation
General points to be observed to ensure EMCcorrect electrical installation.
- Use only screened/armoured motor cables and
screened/armoured control cables.
- Connect the screen to earth at both ends.
- Avoid installation with twisted screen ends (pigtails), since this ruins the screening effect at high
frequencies. Use cable clamps instead.
- It is important to ensure good electrical contact
from the installation plate through the installation
screws to the metal structure of the frequency
converter.
- Use toothed discs and galvanically conductive installation plates.

■ Use of EMC compliant cables
In order to comply with requirements for EMC immunity of the control cables and EMC emissions from
the motor cables screened/armoured cables must be
used.
The ability of a cable to reduce the amount of ingoing and outgoing radiation of electric noise depends
on the transfer impedance (Z
T
). The screen of a cable is normally designed to reduce the transfer of
electric noise, and a screen with a lower Z
T
is more
effective than a screen with a higher Z
T
.
Z
T
is rarely stated by cable manufacturers, but it is
often possible to estimate Z
T
by looking at and as-
sessing the physical design of the cable.
Z
T
can be assessed on the basis of the following
factors:
- the contact resistance between the individual
screen conductors.
- Screen coverage, i.e. the physical area of the cable covered by the screen. Is often stated as a
percentage and should be no less than 85%.
- The screen type, i.e. braided or twisted pattern. A
braided pattern or closed pipe is recommended.

■ Earthing of screened/armoured control cables
In general control cables must be screened/armoured, and the screen must be connected to the
unit’s metal cabinet with a cable clamp at each end.
The drawing below shows the correct way to perform
the earthing, and what to do when in doubt.
1. Correct earthing
Control cables and cables for serial communication must be attached with cable clamps at both
ends to ensure maximum possible electrical contact.
2. Incorrect earthing
Do not use twisted screen ends that are plaited
together (pigtails), as these increase screen
impedance at higher frequencies.
3. Protection with respect to earth potential be-
tween PLC and VLT
If the earth potential between the VLT frequency
converter and the PLC (etc.) is different, electric
noise may occur that will disturb the whole system. This problem can be solved by fitting an
equalising cable, to be placed next to the control
cable. Minimum cable cross-section: 16 mm
2
.
4. In the event of a 50/60 Hz earth loop
If very long control cables are used, 50/60 Hz
earth loops can arise, and these can interfere
with the whole system. This problem is resolved
by attaching one end of the screen to the earth
via a 100 nF capacitor (short pin length).

All types of three-phase asynchronous standard motors can be connected to a frequency converter.
Normally, small motors are star-connected (230/400
V,
1
/ Y). Large motors are delta-connected (400/690
V,
1
/ Y). The correct connection mode and voltage
can be read from the motor nameplate.
NB!:
In motors without phase insulation paper, an
LC filter should be fitted on the output of the
frequency converter.
■ Direction of motor rotation
The factory setting is for clockwise rotation with the
frequency converter transformer output connected
as follows:
Terminal 96 connected to U-phase.
Terminal 97 connected to V-phase.
Terminal 98 connected to W-phase.
The direction of rotation can be changed by switching two phases on the motor terminals.
■ Parallel connection of motors
MG.04.A1.02 - VLT is a registered Danfoss trade mark
39
Installation
VLT®FCD Series
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 I
INV
for the fre-
quency converter.
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.
In systems with motors connected in parallel, the
electronic thermal relay (ETR) of the frequency 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 adap-
tion, 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 iso-
lator or motor relay, the screen must be continued at
the lowest possible HF impedance.
■ Motor thermal protection
The electronic thermal relay in UL-approved frequency converters has received the UL-approval for
single motor protection, when parameter 128 Motor
thermal protection has been set for ETR Trip and
parameter 105 Motor current, I
M, N
has been programmed to the rated motor current (see motor
nameplate).
■ Brake connection

The connection cable to the brake resistor must be

metal cabinet of the frequency converter and to the
metal cabinet of the brake resistor by means of cable clamps. Dimension the cross-section of the
brake cable to match the brake torque.
See chapterDynamic Braking for dimensionering of
brake resistors.
NB!:
Please note that voltages up to 850 V DC occur on the terminals.
MG.04.A1.02 - VLT is a registered Danfoss trade mark

VLT®FCD Series
■ Earth connection
As leak current to the earth is higher than 3.5 mA,
the frequency converter must always be earthed according to prevailing national and local regulations.
To guarantee that the earth cable has a good mechanical connection to PE-termina, the cable cross
section must be at least 10 mm
2
or 2 rated earth
wires that are terminated separately . To increase
safety you can install an RCD (Residual Current Device), which guarantees that the frequency converter
trips when leak current becomes too high. See also
RCD Application Note MN.90.GX.02.
■ Control of mechanical brake
No.
122* 123*
MBR- MBR+ Mechanical brake
(UDC=0.45 X
Mains Voltage)
* (optional)
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, a relay output or digital output (terminal 46). See
Connection of mechanical brake for
further details.
The output must be kept voltage-free for the period
of time during which the frequency converter is not
able to ’support’ the motor, for example due to the
load being too great. If not using the special mechanical brake control/supply terminals (122-123),
select Mechanical brake control in parameter 323 or
341 for applications with an electromagnetic brake.
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 placed at alarm status
or in an overvoltage situation the mechanical brake
is cut in immediately.
NB!:
This application is only
for lifting/lowering without a counterbalance.

■ 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 ca-
bles 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.

Value:
✭Speed regulation, open loop
(SPEED OPEN LOOP)
[0]
Speed regulation, closed loop
(SPEED CLOSED LOOP)
[1]
Process regulation, closed loop
(PROCESS CLOSED LOOP)
[3]
Function:
This parameter is used to select the configuration to
which the frequency converter is to be adapted. This
makes adaptation to a given application simple,
since the parameters not used in a given configuration are hidden (not active).
Description of choice:
If Speed regulation, open loop [0] is selected, normal speed control is obtained (without feedback
signal) with automatic load and slip compensation to
ensure a constant speed at varying loads. Compensations are active, but may be disabled in parameter
134 Load compensation and parameter 136 Slip
compensation as required.
If Speed regulation, closed loop [1] is selected, better speed accuracy is obtained. A feedback signal
must be added, and the PID regulator must be set in
parameter group 400 Special functions.
If Process regulation, closed loop [3] is selected, the
internal process regulator is activated to enable precise regulation of a process in relation to a given
process signal. The process signal can be set to the
relevant process unit or as a percentage. A feedback signal must be added from the process and the

Description of choice:
If Constant torque [1] is selected, a load-dependent
U/f characteristic is obtained, in which output voltage
and output frequency are increased at increasing
loads in order to maintain constant magnetization of
the motor.
Select Variable torque low [2], Variable torque
medium [3] or Variable torque high [4], if the load is
square (centrifugal pumps, fans).
Variable torque - low with CT start [5], - medium with
CT start [6] or high with CT start [7], are selected if
you need a greater breakaway torque than can be
achieved with the three first characteristics.

107 Automatic motor tuning, AMT
(AUTO MOTOR TUN.)
Value:
✭Optimisation off (AMT OFF)
[0]
Optimisation on (AMT START)
[2]
Function:
Automatic motor tuning is an algorithm that measures stator resistance R
S
without the motor axle
turning. This means that the motor is not delivering
any torque.
AMT can be used with benefit when initialising units
where the user wishes to optimise adjustment of the
frequency converter to the motor being used. This is
used in particular when the factory setting does not
sufficiently cover the motor.
For the best possible tuning of the frequency converter it is recommended that AMT is performed on
a cold motor. It should be noted that repeated AMT
runs can cause heating of the motor, resulting in an
increase in the stator resistance R
S
. As a rule, how-
ever, this is not critical.
AMT is performed as follows:
S
tart AMT:
1. Give a STOP signal.
2. Parameter 107 Automatic motor tuning is set at
value [2] Optimisation on.
3. A START signal is given and parameter 107 Auto-
matic motor tuning is reset to [0] when AMT has
been completed.
C
omplete AMT:
AMT is completed by giving a RESET signal. Parameter 108 Stator resistance, Rs is updated with
the optimised value.
I
nterrupting AMT:
AMT can be interrupted during the optimisation procedure by giving a STOP signal.
When using the AMT function the following points
should be observed:
- For AMT to be able to define the motor parame-
ters as well as possible, the correct type plate
data for the motor connected to the frequency
converter must be keyed into parameters 102 to
106.
- Alarms will appear in the display if faults arise
during tuning of the motor.
- As a rule the AMT function will be able to measure the R
S
values for motors that are 1-2 times
larger or smaller than the frequency converter’s
nominal size.
- If you wish to interrupt automatic motor tuning,
press the [STOP/RESET] key.
NB!:
AMT may not be performed on motors connected in parallel, nor may setup changes be
made while AMT is running.
Description of choice:
Select Optimisation on [2] if you want the frequency
converter to perform automatic motor tuning.

■ DC Braking
During DC braking DC voltage is supplied to the motor, and this will cause the shaft to be brought to a
standstill. In parameter 132 DC brake voltage DC
brake voltage can be preset from 0-100%. Max. DC
brake voltage depends on the motor data selected.
In parameter 126 DC braking time DC braking time
is determined and in parameter 127 DC brake cut-in
frequency the frequency at which DC braking
becomes active is selected. If a digital input is programmed to DC braking inverse [5] and shifts from
logic ’1’ to logic ’0’, DC braking will be activated.
When a stop command becomes active, DC braking
is activated when the output frequency is less than
the brake cut-in frequency.

- Via a PTC thermistor that is mounted on the mo-
tor. The thermistor is connected between terminal
31a / 31b. See parameter 300 Digital inputs.
- Thermal load calculation (ETR - Electronic Ther-
mal Relay), based on present load and time. This
is compared with the rated motor current I
M,N
and
rated motor frequency f

. The calculations take
into account the need for lower loading at low
speeds due to the motor’s internal ventilation being reduced.

✭ 0%
Function:
This is where the user selects the minimum motor
current running for the mechanical brake to be released. Current monitoring is only active from stop
until the point when the brake is released.
Description of choice:
This is an extra safety precaution, aimed at guaranteeing that the load is not lost during start of a lifting/
lowering operation.

which the frequency converter itself chooses on the basis of
the motor nameplate data.
144
144 Gain AC brake
(GAIN AC BRAKE)
Value:
1.00 - 1.50
✭ 1.30
Function:
This parameter is used to set the AC brake. Using
par. 144 it is possible to adjust the size of the generator torque that can be applied to the motor without
the intermediate circuit voltage exceeding the warning level.
Description of choice:
The value is increased if a greater possible brake
torque is required. If 1.0 is selected, this corresponds to the AC brake being inactive.
NB!:
If the value in par. 144 is increased, the
motor current will simultaneously increase significantly when generator loads are applied. The
parameter should therefore only be changed if it is
guaranteed during measurement that the motor current in all operating situations will never exceed the
maximum permitted current in the motor. Please

Description of choice:
Select reset (1) when running unique processes
each time they arise. This will enable repetitive precision when stopping to be improved. Select Off (0)
for example for lifting/lowering operations or synchronous motors. It is an advantage that the motor
and the frequency converter are always synchronised.

■ Handling of references
Handling of references is described in the block diagram below. The block diagram shows how a change
in one parameter can affect the resulting reference.
Parameters 203 to 205 Reference and parameter
214 Reference function define how the handling of
references can be performed. The parameters mentioned can be active in both closed and open loop.
Remote controlled references are defined as:
- External references, such as analogue inputs 53
and 60, pulse references via terminal 33 and references from serial communication.
- Preset references
The resulting reference can be shown on the LCP
control unit’s display by selecting Reference [%] in
parameters 009-012 Display readout and can be
shown as one unit by selecting Reference [unit].
The sum of the external references can be shown on
the LCP control unit’s display as a % of the area from
Minimum reference, Ref
MIN
to Maximum reference,
Ref
MAX
. Select External reference, % [25] in parame-
ters 009-012 Display readout if a readout is desired.
It is possible to have both references and external
references simultaneously . In parameter 214 Refer-
ence function a selection can be made to determine
how preset references should be added to the external references.
There is also an independent local reference in parameter 003 Local reference, in which the resulting
reference is set using the [+/-] keys. When the local
reference has been selected, the output frequency
range is limited by parameter 201 Output frequency
low limit, f
MIN
and parameter 202 Output frequency
high limit, f
MAX
.
The local reference unit depends on the selection in
parameter 100 Configuration.

■ Reference function
The example shows how the resulting reference is
calculated when Preset references is used together
with Sum and Relative in parameter 214 Reference
function. The formula for the calculation of the resulting reference can be seen in the section entitled
All about the FCD 300. See also the drawing in
Handling of references.
The following parameters are preset:
Par. 204 Minimum reference 10 Hz
Par. 205 Maximum reference 50 Hz
Par. 215 Preset reference 15 %
Par. 308 Term.53, Analogue input Reference
Par. 309 Term.53, min. scaling 0V
Par. 310 Term.53, max. scaling 10 V
When parameter 214 Reference function is set to
Sum [0] one of the preset Preset references(par.
215-218) is added to the external references as a
percentage of the reference range. If terminal 53 is
applied an analogue input voltage of 4 Volt will be
the resulting reference:
Par. 214 Reference function = Sum [0]:
Par. 204 Minimum reference 10.0 Hz
Reference contribution at 4 Volt 16.0 Hz
Par. 215 Preset reference 6.0 Hz
Resulting reference 32.0 Hz
When parameter 214 Reference function is set to
Relative [1] the defined Preset references (par. 215-
218) are added as a percentage of the total of the
present external references. If terminal 53 is applied
to an analogue input voltage of 4 Volt the resulting
reference will be:
Par. 214 Reference function = Relative [1]:
Par. 204 Minimum reference 10.0 Hz
Reference effect at 4 Volt 16.0 Hz
Par. 215 Preset reference 2.4 Hz

to the external reference, which varies from 0-10
Volt. Parameter 214 Reference function is programmed to Sum [0] and Relative [1] respectively.
Also shown is a graph in which parameter 215 Pre-
set reference 1 is programmed to 0 %.

Function:
In these parameters 302-307 Digital inputs it is possible to choose between the different enabled
functions related to the digital inputs (terminals 18-
33).
Description of choice:
No operation is selected if the frequency converter is
not to react to signals transmitted to the terminal.
Reset resets the frequency converter after an alarm;
however, a few alarms cannot be reset (trip locked)
without first disconnecting the mains supply and reconnecting it. See table under List of warnings and
alarms. Reset is activated on the leading edge of
the signal.
Coasting stop inverse is used for making the frequency converter "let go" of the motor immediately
(output transistors are "turned off"), which means
that the motor runs freely to stop. Logic ’0’ leads to
coasting to stop.
Reset and coasting inverse are used to activate motor coast simultaneously with reset. Logical ’0’
means motor coast stop and reset. Reset is activated on the falling edge.
Quick stop inverse is used for activating the quickstop ramp down set in parameter 212 Quick stop
ramp-down time. Logic ’0’ leads to quick stop.
DC-braking inverse is used for stopping the motor by
energizing it with a DC voltage for a given time, see
parameters 126, 127 and 132 DC brake. Please note
that this function is only active if the value in parameter 126 DC braking time and 132 DC brake voltage
is different from 0. Logic ’0’ leads to DC braking.
Stop inverse, a logic ’0’ means that the motor speed
is ramped down to stop via the selected ramp.
None of the stop commands mentioned
above are to be used as repair switches.
C
heck that all voltage inputs are discon-
n
ected and that the prescribed time (4 mins.) has
p
assed before repair work is commenced.
Start is selected if a start/stop command is required.
Logic ’1’ = start, logic ’0’ = stop.
Latched start, if a pulse is applied for min. 14 ms,
the frequency converter will start the motor, provided
no stop command has been given. The motor can
be stopped by briefly activating Stop inverse.
Reversing is used for changing the direction of rotation of the motor shaft. Logic ’0’ will not lead to
reversing. Logic ’1’ will lead to reversing. The reverse signal only changes the direction of rotation, it
does not activate the start. Is not active at Process
regulation, closed loop. See also parameter 200
Output frequency range/direction.
Reversing and start is used for start/stop and for
reversing with the same signal. No active start command is allowed at the same time. Is not active for
Process regulation, closed loop. See also parameter
200 Output frequency range/direction.
Start clockwise is used if you want the motor shaft
only to be able to rotate clockwise when started.
Should not be used for Process regulation, closed
loop.
Start anticlockwise is used if you want the motor
shaft only to be able to rotate anticlockwise when
started. Should not be used for Process regulation,
closed loop. See also parameter 200 Output frequency range/direction.
Jog is used to override the output frequency to the
jog frequency set in parameter 213 Jog frequency.
Jog is active regardless of whether a start command
has been given, yet not when Coast stop, Quick-stop
or DC braking are active.
Freeze reference freezes the present reference. The
reference can now only be changed via Speed up
and Speed down.Iffreeze reference is active, it will
be saved after a stop command and in the event of
mains failure.
Freeze output freezes the present output frequency
(in Hz). The output frequency can now only be
changed via Speed up and Speed down.

NB!:
If Freeze output is active the frequency con-
verter can only be stopped if you select Motor
coast, Quick stop or DC braking via a digital input.
Speed up and Speed down are selected if digital
control of the up/down speed is required. This function is only active if Freeze reference or Freeze
output frequency has been selected.
If Speed up is active the reference or output frequency will be increased, and if Speed down is
active the reference or output frequency will be reduced. The output frequency is changed via the
preset ramp times in parameters 209-210 Ramp 2.
One pulse (logic ’1’ minimum high for 14 ms and a
minimum break time of 14 ms) will lead to a speed
change of 0.1 % (reference) or 0.1 Hz (output frequency). Example:

Freeze reference can be changed even if the frequency converter has stopped. The reference will
also be saved if the mains are disconnected
Catch-up/Slow-down is selected if the reference
value is to be increased or reduced by a programmable percentage value set in parameter 219
Catch-up/Slow-down reference.

Ramp 2 is selected if a shift between ramp 1
(parameters 207-208) and ramp 2 (parameters 209-
210) is required. Logic ’0’ leads to ramp 1 and logic
’1’ leads to ramp 2.

Preset reference on is used for shifting between
remote-controlled reference and preset reference. It
is assumed that External/preset [2] has been selected in parameter 214 Reference function. Logic
’0’ = remote-controlled references are active, logic ’1’
= one of the four preset references is active, as can
be seen from the table above.
Precise stop, inverse is selected to obtain a high degree of accuracy when a stop command is repeated.
A logic 0 means that the motor speed is ramped
down to stop via the selected ramp.
Precise start/stop is selected to obtain a high degree
of accuracy when a start and stop command is repeated.
Pulse reference is selected if the reference signal
applied is a pulse train (frequency). 0 Hz corresponds to parameter 204 Minimum reference,

Pulse Max 33/29 corresponds to parameter 205

Pulse feedback is selected if the feedback signal
used is a pulse train (frequency). In parameter 327/
328 Pulse Max 33/29 the maximum pulse feedback
frequency is set.
Pulse input is selected if a specific number of pulses
must lead to a Precise stop, see parameter 343 Pre-
cise stop and parameter 344 Counter value.
Selection of Setup, lsb and Selection of Setup, msb
gives the possibility to select one of the four setups.
It is, however, a condition that parameter 004 is set
to Multisetup.
Reset and start can be used as a start function. If
24 V are connected to the digital input, this will
cause the frequency converter to reset and the motor will ramp up to the preset reference.
Encoder reference is selected if the reference signal
applied is a pulse train (frequency). 0 Hz corresponds to parameter 204 Minimum reference,

Description of choice:
Normal ramp stop [0] is selected to achieve high
repetitive precision at the stopping point.
Counter stop. Once it has received a pulse start signal the frequency converter runs until the number of
pulses programmed by the user have been received
at input terminal 33. In this way an internal stop
signal will activate the normal ramp down time (parameter 208).

select the number of times a restart is to be attempted. The time between each attempt is set in
parameter 406 Automatic restart time.
Description of choice:

rial communication. If the frequency converter is to
carry out an automatic reset and restart after a trip,
select data value [1], [3] or [10].

from the motor.
NB!:

output voltage, which means that torque ripple on
the motor shaft is avoided. This can be a good feature, e.g. on grinding machines.

Description of choice:
Select the required unit for the reference/feedback

■ FCD 300 Regulators
The FCD 300 has two integrated PID regulators, one
to regulate speed and one to regulate processes.
Speed regulation and process regulation require a
feedback signal back to an input. There are a number of settings for both PID regulators that are made
in the same parameters, but selection of regulator
type will affect the selections that have to be made
in the shared parameters.
In parameter 100 Configuration it is possible to select regulator type, Speed regulation, closed loop [1]
or Process regulation, closed loop [3].
S
peed regulation
This PID regulation is optimised for use in applications in which there is a need to maintain a
particular motor speed. The parameters that are
specific for the speed regulator are parameter 417 to
parameter 421.
P
rocess regulation
The PID regulator maintains a constant process
mode (pressure, temperature, flow, etc.) and adjusts
the motor speed on the basis of the reference/setpoint and feedback signal.
A transmitter provides the PID regulator with a feedback signal from the process as an expression of the
process’s actual mode. The feedback signal varies
as the process load varies.
This means that there is a variance between the reference/setpoint and the actual process mode. This
variance is compensated by the PID regulator by
means of the output frequency being regulated up or
down in relation to the variance between the reference/setpoint and the feedback signal.
The integrated PID regulator in the frequency
converter has been optimised for use in process applications. This means that there are a number of
special functions available in the frequency converter.
Previously it was necessary to obtain a system to
handle these special functions by installing extra I/O
modules and programming the system. With the frequency converter the need to install extra modules
can be avoided. The parameters that are specificto
the Process Regulator are parameter 437 to parameter 444.
■ PID functions
U
nit of reference/feedback
When Speed regulation, closed loop is selected in
parameter 100 Configuration the unit of reference/
feedback is always rpm.
When Process regulation, closed loop is selected in
parameter 100 Configuration the unit is defined in
parameter 416 Process units.
F
eedback
A feedback range must be preset for both regulators.
At the same time this feedback range limits the potential reference range so that if the sum of all
references lies outside the feedback range, the reference will be limited to lie within the feedback range.
The feedback signal must be connected to a terminal on the frequency converter. If feedback is
selected on two terminals simultaneously , the two
signals will be added together.
Use the overview below to determine which terminal
is to be used and which parameters are to be programmed.
Feedback type Terminal Parameters
Pulse 29, 33 305, 307, 327,
328
Voltage 53 308, 309, 310
Current 60 314, 315, 316
A correction can be made for loss of voltage in long
signal cables when a transmitter with a voltage output is used. This is done in parameter group 300
Min./Max scaling.

Parameters 414/415 Minimum/Maximum feedback
must also be preset to a value in the process unit
corresponding to the minimum and maximum scaling
values for signals that are connected to the terminal.
R
eference
In parameter 205 Maximum reference, Ref
MAX
it is
possible to preset a maximum reference that scales
the sum of all references, i.e. the resulting reference.
The minimum reference in parameter 204 is an expression of the minimum value that the resulting
reference can assume.
All references will be added together and the sum
will be the reference against which regulation will
take place. It is possible to limit the reference range
to a range that is smaller than the feedback range.
This can be an advantage if you want to avoid an
unintentional change to an external reference making the sum of the references move too far away
from the optimal reference. The reference range
cannot exceed the feedback range.
If preset references are desired, they are preset in
parameters 215 to 218 Preset reference. See
description Reference Function and Handling of Ref-
erences.
If a current signal is used as the feedback signal, it
will only be possible to use voltage as an analogue
reference. Use the overview below to determine
which terminal is to be used and which parameters
are to be programmed.

NB!:

D
ifferentiator gain limit
If very rapid variations occur in an application in either the reference signal or the feedback signal, the
deviation between the reference/setpoint and the
process’s actual mode will change quickly. The differentiator can then become too dominant. This is
because it is reacting to the deviation between the
reference and the process’s actual mode, and the
quicker the variance changes the more powerful the
differentiator’s frequency contribution becomes. The
differentiator’s frequency contribution can therefore
be limited in such a way that both a reasonable
differentiation time for slow changes and an appropriate frequency contribution for quick changes can
be preset. This is done using the speed regulation in
parameter 420 Speed PID Differentiator gain limit
and Process regulation in parameter 443 Process
PID Differentiator gain limit.
L
owpass filter
If there is a lot of noise in the feedback signal, these
can be dampened using an integratedlowpass filter.
A suitable lowpass filter time constant is preset.
If the lowpass filter is preset to 0.1 s, the cut-off frequency will be 10 RAD/sec, corresponding to (10 / 2
x
) = 1.6 Hz. This will mean that all currents/voltages that vary by more than 1.6 oscillations per
second will be dampened. In other words, there will
only be regulation on the basis of a feedback signal
that varies by a frequency of less than 1.6 Hz. The
appropriate time constant is selected in Speed Regulation in parameter 421 Speed PID lowpass filter
time and in Process Regulation in parameter 444
Process PID lowpass filter time.
I
nverse regulation
Normal regulation means that the motor speed is increased when the reference/setpoint is greater than
the feedback signal. If it is necessary to run inverse
regulation, in which the speed is reduced when the
reference/setpoint is greater than the feedback signal, parameter 437 PID normal/inverted control must
be programmed at Inverted.
A
nti Windup
In the factory the process regulator is preset with an
active anti windup function. This function means that
when either a frequency limit, a current limit or a
voltage limit is reached, the integrator is initialised at
a frequency corresponding to the present output frequency. This is a means of avoiding the integration of
a variance between the reference and the process’s
actual mode that cannot be deregulated by means of
a change of speed. This function can be deselected
in parameter 438 Process PID anti windup.

Starting conditions
In some applications the optimal setting of the process regulator will mean that a relatively long period
of time will pass before the required process condition is achieved. In these applications it can be a
good idea to define an output frequency to which the
frequency converter must run the motor before the
process regulator is activated. This is done by programming a start frequency in parameter 439
Process PID start frequency.

Feedback handling is depicted in this flowchart.
The flowchart shows which parameters can affect
the handling of feedback and how. A choice can be

417
417 Speed PID proportional gain
(SPEED PROP GAIN)
Value:
0.000 (OFF) - 1.000
✭ 0.010
Function:
Proportional gain indicates how many times the fault
(deviation between the feedback signal and the setpoint) is to be amplified.
Description of choice:
Quick regulation is obtained at high amplification, but
if the amplification is too high, the process may become unstable in the case of overshooting.
418
418 Speed PID integral time
(SPEED INT. TIME)
Value:
20.00 - 999.99 ms (1000 = OFF)
✭ 100 ms
Function:
The integral time determines how long the PID regulator takes to correct the error. The greater the error,
the quicker the integrator frequency contribution will
increase. The integral time is the time the integrator
needs to achieve the same change as the proportional amplification.
Description of choice:
Quick regulation is obtained through a short integral
time. However, if this time is too short, it can make
the process unstable. If the integral time is long, major deviations from the required reference may occur,
since the process regulator will take long to regulate
if an error has occurred.
419
419 Speed PID differential time
(SPEED DIFF. TIME)
Value:
0.00 (OFF) - 200.00 ms
✭ 20.00 ms
Function:
The differentiator does not react to a constant error.
It only makes a contribution when the error changes.
The quicker the error changes, the stronger the gain
from the differentiator will be. The contribution is
proportional to the speed at which errors change.
Description of choice:
Quick control is obtained by a long differential time.
However, if this time is too long, it can make the process unstable. When the differential time is 0 ms,
the D-function is not active.
420
420 Speed PID D- gain limit
(SPEED D-GAIN LIM)
Value:
5.0 - 50.0
✭ 5.0
Function:
It is possible to set a limit for the gain provided by
the differentiator. Since the D-gain increases at
higher frequencies, limiting the gain may be useful.
This enables obtaining a pure D-gain at low frequencies and a constant D-gain at higher frequencies.
Description of choice:
Select the required gain limit.
421
421 Speed PID lowpass filter time
(SPEED FILT. TIME)
Value:
20 - 500 ms
✭ 100 ms
Function:
Noise in the feedback signal is dampened by a first
order lowpass filter to reduce the noise’s impact on
the regulation. This might be an advantage, e.g. if
there is a great amount of noise on the signal. See
drawing.

Description of choice:
If a time constant (t) of 100 ms is programmed, the
cut-off frequency for the lowpass filter will be 1/0.1 =
10 RAD/sec., corresponding to (10 / 2 x
) = 1.6 Hz.
The PID regulator will then only regulate a feedback
signal that varies with a frequency of less than 1.6
Hz. If the feedback signal varies by a higher frequency than 1.6 Hz, it will be dampened by the
lowpass filter.

when the deviation changes its sign, the integrator will first have to integrate down from the level
obtained as a result of the former error, before any
change in output frequency occurs.

(PROC START VALUE)
Value:
f
MIN
-f
MAX
(parameter 201/202)
✭ Par. 201 Output frequency, low limit, f
MIN
Function:
When the start signal comes, the frequency converter will react in the form of Open loop and will not
change to Closed loop until the programmed start
frequency is reached. This makes it possible to set a
frequency that corresponds to the speed at which
the process normally runs, which will enable the required process conditions to be reached sooner.
Description of choice:
Set the required start frequency.
NB!:
If the frequency converter is running a the cur-
rent limit before the required start frequency is
obtained, the process regulator will not be activated.
For the regulator to be activated anyway, the start
frequency must be lower to the required output frequency. This can be done during operation.
440
440 Proces PID proportioanl gain
(PROC. PROP. GAIN)
Value:
0.0 - 10.00
✭ 0.01
Function:
The proportional gain indicates the number of times
the deviation between the setpoint and the feedback
signal is to be applied.
Description of choice:
Quick regulation is obtained by a high gain, but if the
gain is too high, the process may become unstable
due to overshoot.
441
441 Process PID integration time
(PROC. INTEGR. T.)
Value:
0.01 - 9999.99 (OFF)
✭ OFF
Function:
The integrator provides an increasing gain at a constant error between the reference/setpoint and the
feedback signal. The greater the error, the quicker
the integrator frequency contribution will increase.The integral time is the time needed by the
integrator to make the same change as the proportional gain.
Description of choice:
Quick regulation is obtained at a short integral time.
However, this time may become too short, which can
make the process unstable due to overswing. If the
integral time is long, major deviations from the
required setpoint may occur, since the process regulator will take a long time to regulate in relation to a
given error.
442
442 Process PID differentiation time
(PROC. DIFF. TIME)
Value:
0.00 (OFF) - 10.00 sec.
✭ 0.00 sec.
Function:
The differentiator does not react to a constant error.
It only makes a gain when an error changes. The
quicker the deviation changes, the stronger the gain
from the differentiator. The gain is proportional to
the speed at which the deviation changes.
Description of choice:
Quick regulation is obtained with a long differentiation time. However, this time may become too long,

which can make the process unstable due to overswing.
443
443 Process PID diff. gain limit
(PROC. DIFF.GAIN)
Value:
5.0 - 50.0
✭ 5.0
Function:
It is possible to set a limit for the differentiator gain.
The differentiator gain will increase if there are fast
changes, which is why it can be beneficial to limit
this gain. Thereby a pure differentiator gain is obtained at slow changes and a constant differentiator
gain where quick changes to the deviation occur.
Description of choice:
Select a differentiator gain limit as required.
444
444 Process PID lowpass filter time
(PROC FILTER TIME)
Value:
0.02 - 10.00
✭ 0.02
Function:
Noise in the feedback signal is dampened by a first
order lowpass filter to reduce the noise’s impact on
the process regulation. This can be an advantage
e.g. if there is a lot of noise on the signal.
Description of choice:
Select the required time constant (t). If a time
constant (t) of 0.1 s is programmed, the cut-off frequency for the lowpass filter will be 1/0.1 = 10 RAD/
sec., corresponding to (10 / 2 x
) = 1.6 Hz. The
process regulator will thus only regulate a feedback
signal that varies by a frequency lower than 1.6 Hz.
If the feedback signal varies by a higher frequency
than 1.6 Hz, it will be dampened by the lowpass filter.

OK - same direction
(OK-SAME DIRECTION)

[2]
DC brake and start
(DC-BRAKE BEF. START)
[3]
Function:
This function makes it possible to ’catch’ a rotating
motor shaft, which is no longer controlled by the frequency converter, e.g. because of a mains drop-out.
The function is activated each time a start command
is enabled. For the frequency converter to be able to
’catch’ the rotating motor shaft, the motor speed
must be lower than the frequency that corresponds
to the frequency in parameter 202 Output frequency,
high limit, f
MAX
.
Description of choice:
Select Disable [0] if this function is not required.
Select OK - same direction [1] if the motor shaft is
only able to rotate in the same direction when cutting
in. OK - same direction [1] should be selected if in
parameter 200 Output frequency range a selection
has been of Clockwise only.
Select OK - both directions [2] if the motor is able to
rotate in both directions when cutting in.
Select DC brake and start [3] if the frequency converter is to be able to brake the motor using the DC
brake first, followed by start. It is assumed that parameters 126-127/132 DC brake are enabled. In the
case of higher ’Windmilling’ (rotating motor) effects,
the frequency converter is not able to ’catch’ a rotating motor without selecting DC brake and start.
Limitations:
- Too low inertia will lead to load acceleration,
which can be dangerous or prevent correct catching of a rotating motor. Use the DC brake instead.
- If the load is driven, e.g. by ’Windmilling’ (rotating
motor) effects, the unit may cut out because of
overvoltage.
- Flying start does not work at lower values than
250 rpm.

(FEEDFORWARD FACT)
Value:
0 - 500 %
✭ 100 %
Function:
This parameter is only active if in parameter 100
Configuration the selection made is Speed regulation, closed loop. The FF function sends a larger or
smaller part of the reference signal outside the PID
controller in such a way that the PID controller only
has an influence on part of the control signal. Any
change to the set point will thus have a direct effect

Function:
The user sets the voltage by which the level for

Description of choice:
The greater the reduction value, the faster the reaction to a generator overload. Should only be used if
there are problems with overvoltage in the intermediate circuit.

■ Serial communication for FCD 300
■ Protocols
All frequency converters are equipped with an RS
485 port as standard, which makes it possible to
choose between two protocols. The two protocols
that can be selected in parameter 512
Telegram Pro-
file, are:
• Profidrive protocol
• Danfoss FC protocol
To select Danfoss FC protocol, parameter 512 Telegram Profile is set to FC protocol [1].
■ Telegram Traffic
C
ontrol and response telegrams
Telegram traffic in a master-slave system is controlled by the master. A maximum of 31 slaves can
be connected to a master, unless repeaters are
used. If repeaters are used, a maximum of 126
slaves can be connected to a master.
The master constantly sends telegrams addressed
to the slaves and waits for response telegrams from
them. The slave’s response time is a maximum of
50 ms.
Only a slave that has received an error-free telegram, addressed to that slave can send a response
telegram.
B
roadcast
A master can send the same telegram simultaneously to all slaves connected to the bus. During this
broadcast communication the slave does not send
any response telegrams back to the master as to
whether the telegram has been correctly received.
Broadcast communication is set up in address format (ADR), see Telegram structure.
C
ontent of a character (byte)
Each character transferred begins with a start bit.
Then 8 data bits are transferred, corresponding to a
byte. Each character is secured via a parity bit,
which is set at "1" when it reaches parity (i.e. when
there is an equal number of 1’s in the 8 data bits
and the parity bit in total). A character is completed
by a stop bit, thus consisting of 11 bits in all.
■ Telegram Structure
Each telegram begins with a start character (STX) =
02 Hex, followed by a byte that denotes the length of
the telegram (LGE) and a byte that denotes the
address of the frequency converter (ADR). Then follows a number of data bytes (variable, depending on
the type of telegram). The telegram is completed by
a data control byte (BCC).
Telegram times
The communication speed between a master and a
slave depends on the baud rate. The frequency converter’s baud rate must be the same as the master’s
baud rate and be selected in parameter 501 Bau-
drate.
After a response telegram from the slave, there must
be a pause of at least 2 characters (22 bits) before
the master can send a new telegram. At a baud rate
of 9600 baud there must be a pause of at least 2.3
ms. When the master has completed the telegram,
the slave’s response time back to the master will be
a maximum of 20 ms, and there will be pause of at
least 2 characters.
Pause time, min: 2 characters
Response time, min: 2 characters
MG.04.A1.02 - VLT is a registered Danfoss trade mark
94
VLT®FCD Series
Response time, max: 20 ms
The time between the individual characters in a telegram may not exceed 2 characters and the telegram
must be completed within 1.5 x nominal telegram
time. At a baud rate of 9600 baud and a telegram
length of 16 bytes the telegram will be completed after 27.5 msec.
Telegram length ( LGE)
The telegram length is the number of data bytes plus
the address byte ADR plus the data control byte
BCC.
The length of telegrams with 4 data bytes is:
LGE = 4 + 1 + 1 = 6 bytes
The length of telegrams with 12 data bytes is:
LGE = 12 + 1 + 1 = 14 bytes
The length of telegrams containing texts is 10+n
bytes. 10 represents the fixed characters, while the
’n’ is variable (depending on the length of the text).
F
requency converter address (ADR)
Two different address formats are used, with the frequency converter’s address range being either 1-31
or 1-126.
1. Address format 1-31
The byte for address range 1-31 has the following
profile:
Bit 7 = 0 (address format 1-31 active)
Bit 6 is not used
Bit 5 = 1: Broadcast, address bits (0-4) are not
used
Bit 5 = 0: No Broadcast
Bit 0-4 = Frequency converter address 1-31
2. Address format 1-126
The byte for address range 1 - 126 has the following
profile:
Bit 7 = 1 (address format 1-126 active)
Bit 0-6 = Frequency converter address 1-126
Bit 0-6 = 0 Broadcast
The slave sends the address byte back unchanged
in the response telegram to the master.
E
xample:
writing to frequency converter address 22 with address format 1-31:
Data control byte (BCC)
The data control byte is explained in this example:
Before the first byte in the telegram is received, the
Calculated CheckSum (BCS) is 0.
When the first byte (02H) has been received:
BCS = BCC EXOR “first byte”
(EXOR = exclusive-or gate)
BCS =00000000
EXOR
1.byte =00000010(02H)
BCC =00000010
Each subsequent byte gates with BCS EXOR and
produces a new BCC, e.g.:
BCS =00000010
EXOR
2ndbyte =11010110(D6H)
BCC =11010100

■ Data Character (byte)
The structure of data blocks depends on the type of
telegram. There are three types of telegram, and the
type of telegram applies for both control telegrams
(master ⇒slave) and response telegrams
(slave⇒master). The three types of telegram are:
- Parameter block, used to transfer parameters between master and slave. The data block is made
up of 12 bytes (6 words) and also contains the
process block.
- The process block is made up of a data block of
four bytes (2 words) and contains :
- Control word and reference value
- Status word and present output frequency
(from slave to master)
- Text block, which is used to read or write texts via
the data block.
Parameter commands and responses (AK).
Bits no. 12-15 are used to transfer parameter
commands from master to slave and the slave’s processed responses back to the master.
Parameter commands master⇒slave
Bit no.

I
ndex
Index is used together with the parameter number to
read/write-access parameters that have an index,
e.g. parameter 615 Error code. The index is made
up of 2 bytes, one lowbyte and one highbyte, but
only the lowbyte is used as an index.
E
xample - Index:
The first error code (index [1]) in parameter 615 Er-
ror code must be read.
PKE = 1267 Hex (read parameter 615 Error code.)
IND = 0001 Hex - Index no. 1.
The frequency converter will respond in the parameter value block (PWE) with a fault code value from 1
- 99. See Summary of Warnings and Alarms to
identify the fault code.
Parameter value (PWE)
The parameter value block consists of 2 words (4
bytes), and the value depends on the defined command (AK). If the master prompts for a parameter
value, the PWE block does not contain a value.
If you wish the master to change a parameter value
(write), the new value is written in the PWE block
and sent to the slave.
If the slave responds to a parameter request (read
command), the present parameter value in the PWE
block is transferred and returned to the master.
If a parameter contains not a numerical value, but
several data options, e.g. parameter 001 Language
where [0] corresponds to English, and [3] corresponds to Danish, the data value is selected by
entering the value in the PWE block. See Example -
Selecting a data value.
Via serial communication it is only possible to read
parameters that have data type 9 (text string). Parameter 621 - 635 Nameplate data is data type 9.
For example, in parameter 621 Unit type it is possible to read the unit size and mains voltage range.
When a text string is transferred (read) the length of
the telegram is variable, as the texts are of different
lengths. The telegram length is defined in the telegram’s second byte, known as LGE.
To be able to read a text via the PWE block the parameter command (AK) must be set to ’F’ Hex.
The index character is used to indicate whether it is
a read or write command.
In a read command the index must have the following format:

Some frequency converters have parameters to
which a text may be written. To be able to write a
text via the PWE block the parameter command
(AK) must be set to ’F’ Hex.
For a write command the text must have the following format:
Data types supported by frequency transformer:
Data types Description
3 Integer 16
4 Integer 32
5 Unsigned 8
6 Unsigned 16
7 Unsigned 32
9 Text string
Unsigned means that there is no operational sign in
the telegram.
Example - Write a parameter value :
Parameter 202 Output frequency high limit, f
MAX
to
be changed to 100 Hz. The value must be recalled
after a mains failure, so it is written in EEPROM.

PWE
HIGH
= 0000 Hex
PWE
LOW
= 0000 Hex
If the value in parameter 207 Ramp-up time 1 is 10

Conversion:
Under the section entitled Factory Settings the various attributes of each parameter are displayed. As a
parameter value can only be transferred as a whole
number, a conversion factor must be used to transfer
decimals.
E
xample:
Parameter 201 Output frequency, low limit f
MIN
has a
conversion factor of 0.1. If you wish to preset the
minimum frequency to 10 Hz, the value 100 must be
transferred, as a conversion factor of 0.1 means that
the value transferred is multiplied by 0.1. The value
100 will thus be perceived as 10.0.

made to define how Bit 02 gates with the corresponding function on a digital input.
B
it 03, Coasting stop:
Bit 03 = ’0’ causes the frequency converter to immediately "let go" of the motor (the output transistors
are "shut off"), so that it coasts to a standstill.
Bit 03 = ’1’ causes the frequency converter to be
able start the motor if the other starting conditions

only be changed by means of the digital inputs programmed to Speed up and Speed down.
NB!:
If Freeze output is active, the frequency con-
verter cannot be stopped via Bit 06 Start or

be stopped by the following:
• Bit 03 Coasting stop
• Bit 02 DC braking
• Digital input programmed to DC braking, Coasting
