■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

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 forambient temperature. Pleasenotethattheservicelife
of the frequency converter will be reduced if derating
for ambient temperature is not considered.

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.

■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

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
or in an overvoltage situation the mechanical
brake is cut in immediately.
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.
A relay output or digital output (terminal 46)
can be used. See Connection of mechanicalbrake for further details.

■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.

Value:
✭Optimisation off (AMT OFF)
Optimisation on (AMT START)
Function:
Automatic motor tuning is an algorithm that measures
stator resistance R
without the motor axle turning.
S
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
.Asa
S
rule, however, this is not critical.
AMT is performed as follows:
S
tart AMT:
1. Give a STOP signal.
2. Parameter 107 Automatic motor tuning is se t
at value [2] Optimisation on.
3. A START signal is given and parameter 107
Automatic motor tuning is r e set to [0 ] when
AMT has been completed.
In factory setting START requires terminals 18 and
27 to be connected to terminal 12.
omplete AMT:
C
AMT is completed by giving a RESET signal.
Parameter 108 Stator resistance, Rs is updated
with the optimised value.
nterrupting AMT:
I
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 paramete
as well as possible, the correct type plate data for
[0]
[2]
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
values for motors that are 1-2 times larger or
the R
S
smaller than the frequency converter’snominalsize.
- 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.

■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-infrequency 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.
NB!:
DC braking may not be used if the inertia in
the motor shaft is more than 20 times greater
than the motor’s internal inertia.

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 Listof 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’ leadstocoastingtostop.
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 quick-stop
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 i
126 DC braking time and 132 DC brake voltage is

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

Description of choice:
Precise 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).
The counter function is activated (starts timing) at
the flank of the start signal (when it changes
from stop to start).
Speed compensated stop.Tostopatprecisely
the same point, regardless of the present speed,
a stop signal received is delayed internally when
the present speed is lower than the maximum
speed (set in parameter 202).
Reset. Counter stop and Speed-compensated stop
can be combined with or without reset.
Counter stop with reset [1]. After each precise
stop the number of pulses counted during
ramp down 0 Hz is reset.
Counter stop without reset [2]. The number of pulses
counted during ramp down to 0 Hz is deducted
from the counter value in parameter 344.

■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
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
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 specific to the Process Regulator are
parameter 437 to parameter 444.

ifferentiator gain limit
D
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.
Thedifferentiator 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.
owpass filter
L
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 π) = 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 lowpassfilter time and in Process Regulation in parameter
444 Process PID lowpass filter time.
nverse regulation
I
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/invertedcontrol must be programmed at Inverted .

that when either a frequency limit, a current limit or

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.
■Handling of feedback
Feedback handling is depicted in this flowchart.
tarting conditions
S
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.
The flowchart shows which parameters can affect the
handling of feedback and how. A choice can be made
between voltage, current and pulse feedback signals.

417 Speed PID proportional gain
(SPEED PROP GAIN)
Value:
0.000 (OFF) - 1.000
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 Speed PID integral time

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 Speed PID D- gain limit
(SPEED D-GAIN LIM)
Value:
5.0 - 50.0
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.
✭ 5.0
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.

✭ 20.00 ms
421 Speed PID lowpass filter time
(SPEED FILT. TIME)
Value:

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 =

The PID regulator will then only regulate a feedback

Function:
It is possible to choose whether the process regulator
is to increase/reduce the output frequency if there
is a deviation between the reference/setpoint
and the actual process mode.

Value:
Not active (DISABLE)
✭Active (ENABLE)
Function:
It is possible to select whether the process regulator is
to continue regulating on a deviation even if it is not
possible to increase/reduce the output frequency.
Description of choice:
The factory setting is Enable [1], which means that
the integration link is initialised in relation to the
actual output frequency if either the current limit, the
voltage limit or the max./min. frequency has been
reached. The process regulator will not engage
again until either the error is zero or its sign has
changed. Select Disable [0] if the integrator is to
continue integrating on the deviation, even if it is not
possible to remove the fault by such control.
NB!:
If Disable [0] is selected, it will mean that 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.

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.

If the frequency converter is running a the
current 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 Proces PID proportioanl gain
(PROC. PROP. GAIN)
Value:
0.0 - 10.00
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.

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 Process PID diff. gain limit
(PROC. DIFF.GAIN)
Value:
5.0 - 50.0
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.
✭ 0.00 sec.
✭ 5.0
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.
Description of choice:
Select a differentiator gain limit as required.
444 Process PID lowpass filter time
(PROC FILTER TIME)
Value:
0.02 - 10.00
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 π) = 1.6 Hz. The process
regulator will thus only regulate a feedback signal
that varies by a frequency lower than 1.6 Hz. I

■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 Te legram Profile ,are:
• Profidrive protocol
• Danfoss FC protocol
To select Danfoss FC protocol, parameter 512
Telegram Profile is set to FC protocol [1].
■Telegram Traffic
ontrol and response telegrams
C
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.
VLT®FCD Series
■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 timing
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 Baudrate.
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.
300
Programming, FCD
Only a slave that has received an error-free telegram,
addressed to that slave can send a response telegram.
roadcast
B
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.
ontent of a character (byte)
C
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’sinthe8databits
and the parity bit in total). A character is completed
by a stop bit, thus consisting of 11 bits in all.

Telegram length (LGE)
The telegram length is the number of data bytes plus
theaddressbyteADRplusthedatacontrolbyteBCC.
The length of telegrams with 4 data bytes is:
LGE=4+1+1=6bytes
The length of telegrams with 12 data bytes is:
LGE=12+1+1=14bytes
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).
requency converter address (ADR)
F
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:

BCS=00000000(00H)
EXOR
1. byte=00000010(02H)
BCC=00000010(02H)
Each subsequent byte gates with BCS EXOR
and produces a new BCC, e.g.:

the following profile:
Bit 7 = 1 (address format 1-126 active)
Bit 0-6 = Frequency converter address 1-126

■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)

Via serial communication it is only possible to read
parameters that have data type 9 (text string).
Parameter 621 - 635 Nameplate data is data ty p e 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 w rite co mmand.
In a read command the index must have
the following format:
The frequency converter will respond in the
parameter value block (PWE) with a fault code
value from 1 - 99. See Summary of Warningsand Alarms to identify the fault code.
Parameter value (PWE)
The parameter value block consists of 2 wor
ds
(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 v
alue.
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

(M.BUS PAR./FRAME)
Value:
(EVEN/1 STOPBIT)
(ODD/1 STOPBIT)
✭ (NO PARITY/1 STOPBIT)
(NO PARITY/2 STOPBIT)
Function:
This parameter sets up the drive’sModbusRTU
interface to communicate properly with the master
controller. The parity (EVEN, ODD, or NO PARITY) must
be set to match the setting of the master controller.
Description of choice:
Select the parity that matches the setting for the
Modbus master controller. Even or odd parity is
sometimes used to allow a transmitted word to be
checked for errors. Because Modbus RTU uses
the more efficient CRC (Cyclic Redundancy Check)
method of checking for errors, parity checking is
seldom used in Modbus RTU networks.

571 Modbus communications timeout
(M.BUS COM.TIME.)
Value:
10 ms - 2000 ms
Function:
This parameter determines the maximum amount
of time that the drive’s Modbus RTU will wait
between characters that are sent by the master
controller. When this amount of time expires, the
drive’s Modbus RTU interface will assume that it
has received the entire message.
Description of choice:
Generally, the value of 100 ms is sufficient for Modbus
RTU networks, although some Modbus RTU networks
may operate on a timeout value as short as 35 ms.
If this value is set too short, the drive’s Modbus RTU
interface may miss a part of the message. Since the
CRC check will not be valid, the drive will ignore the
message. The resulting retransmissions of messages
will slow communications on the network.
If this value is set too long, the drive will wait longer
than necessary to determine that the message is
completed. This will delay the drive’s response to the
message and possibly cause the master controller to
time out. The resulting retransmissions of messages
will slow communications on the network.
