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

Installation
VLT®FCD Series
■ 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.
