"Power Factor
The power factor is the relation between I1and IRMS.
The power factor for 3-phase control:
The power factor indicates to which extent
the frequency converter imposes a load
on the mains supply.
The lower the power factor, the higher the IRMS
for the same kW performance.
In addition, a high power factor indicates that the different harmonic currents are low.
The FC 300 frequency converters’ built-in DC coils produce a high power factor, which
minimises the imposed load on the mains supply.

"CE Conformity and Labelling
What is CE Conformity and Labelling?
The purpose of CE labelling is to avoid technical trade obstacles 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 of January 1, 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)
15
MG.33.B4.02 - VLT is a registered Danfoss trademark

FC 300 Design Guide
Introduction to FC 300
Frequency converters must be CE labelled in accordance with the low-voltage directive of
January 1, 1997. The directive applies to all electrical equipment and appliances used in the
50 - 1000 V AC and the 75 - 1500 V 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 does not affect the way the appliances work.
The EMC directive came into effect January 1, 1996. Danfoss CE-labels in accordance with the directive and
issues a declaration of conformity upon request. To carry out EMC-correct installation, see the instructions in
this Design Guide. In addition, we specify which standards our products comply with. We offer the filters
presented in the specifications and provide other types of assistance to ensure the optimum EMC result.
The frequency converter is most often 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.
"What Is Covered
The EU "Guidelines on the Application of Council Directive 89/336/EEC" outline three typical situations
of using a frequency converter. See below for EMC coverage and CE labelling.
1. The frequency converter is sold directly to the end-consumer. The frequency converter is for example
sold to a DIY market. The end-consumer is a layman. He installs the frequency converter himself
for use with a hobby machine, a kitchen appliance, etc. For such applications, the frequency
converter must be CE labelled in accordance with the EMC directive.
2. The frequency converter is sold for installation in a plant. The plant is built up by professionals of the
trade. It could be a production plant or a heating/ventilation plant designed and installed by professionals
of the trade. Neither the frequency converter nor the finished plant has to be CE labelled under the EMC
directive. However, the unit must comply with the basic EMC requirements of the directive. This is
ensured by using components, appliances, and systems that are CE labelled under the EMC directive.
3. The frequency converter is sold as part of a complete system. The system is being marketed as
complete and could e.g. be an air-conditioning system. The complete system must be CE labelled
in accordance with the EMC directive. The manufacturer can ensure CE labelling under the EMC
directive either by using CE labelled components or by testing the EMC of the system. If he chooses
to use only CE labelled components, he does not have to test the entire system.
"Danfoss VLT Frequency Converter
and CE Labelling
CE labelling is a positive feature when used for its original purpose, i.e. to facilitate trade within the EU and EFTA.
However, CE labelling may cover many different specifications. Thus, you have to check
what a given CE label specifically covers.
The covered specifications can be very different and a CE label may therefore give the installer a false
feeling of security when using a frequency converter as a component in a system or an appliance.
Danfoss CE labels the frequency converters in accordance with the low-voltage directive. This means that if
the frequency converter is installed correctly, we guarantee compliance with the low-voltage directive. Danfoss
issues a declaration of conformity that confirms our CE labelling in accordance with the low-voltage directive.
The CE label also applies to the EMC directive provided that the instructions for EMC-correct installation and
filtering are followed. On this basis, a declaration of conformity in accordance with the EMC directive is issued.
The Design Guide offers detailed instructions for installation to ensure EMC-correct installation.
Furthermore, Danfoss specifies which our different products comply with.

FC 300 Design Guide
Introduction to FC 300
Danfoss gladly provides other types of assistance that can help you obtain the best EMC result.
"Compliance with EMC Directive 89/336/EEC
As mentioned, the frequency converter is mostly 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.
As an aid to the installer, Danfoss has prepared EMC installation guidelines for the Power Drive System.
The standards and test levels stated for Power Drive Systems are complied with, provided that the
EMC-correct instructions for installation are followed, see section Electrical Installation.
"Mechanical Build-Up

MG.33.B4.02 - VLT is a registered Danfoss trademark

FC 300 Design Guide
Introduction to FC 300
ACold plate technology
The frequency converter is built upon a very stable aluminium base integrated with the back panel.
This provides high mechanical stability, efficient cooling and the possibility of cold plate operation. The
cold plate serves as a flat cooling surface on the frequency converter, where a majority of the heat
losses dissipates from the electronics to an external cooling surface.
BDC coil
The built-in DC coil ensures low harmonic disturbance of the power supply according to IEC-1000-3-2.
CAir guiding screen
The screen allows cold air to pass by the electronics only. The plastic air guide screen is enclosed in
the package and is easily snapped in place. If the frequency converter is to operate as a cold plate
drive, the air guiding screen is inserted in the cooling channel through the bottom of the drive if it
is snapped unto the fan. Thus, the amount of heat transferred to the surroundings via the cooling
air from the fan is reduced.
DRemovable fan
Like most of the elements, the fan can easily be removed for easy cleaning and remounted.

The frequency converter comes standard prepared for installations with the safe stop functionality
for stop category 0 (EN 60204-1) with safety category 3 (EN 954-1). This feature prevents the
drive from starting unintended.
FControl terminals
Spring-loaded cage clamps, screw less terminals, add to reliability and facilitate easy commissioning
and service.
GOptions
Options for bus communication, I/O extension etc. can be delivered extra or ordered built-in (and
tested together with the drive) from the factory. Options mounted under the LCP are referred to as
option Slot A (top) and option Slot B (bottom). Option C is mounted on the side of the drive, while
option D is mounted underneath the control cable decoupling plate.
HLocal Control Panel
The LCP 102 has a graphical user-interface. Choose between 27 built-in languages (including Chinese)
or have it customised with your own languages and phrases.
Additionally a simple version, LCP 101, is available with an alpha- numeric display. A complete
programming of FC 301 and FC 302 can be handled by both LCP’s.
JHot plugable LCP
The LCP can be plugged in or out during operation. Settings are easily transferred via the control panel
from one drive to another or from a PC with the MCT-10 set-up software.
"Air Humidity
The frequency converter has been designed to meet the IEC/EN 60068-2-3 stan-
dard, EN 50178 pkt. 9.4.2.2 at 50°C.
"Aggressive Environments
A frequency converter contains a large number of mechanical and electronic components. All
are to some extent vulnerable to environmental effects.

Introduction to FC 300
The frequency converter should not be installed in environments with airborne
liquids, particles, or gases capable of affecting and damaging the electronic
components. Failure to take the necessary protective measures increases the risk
of stoppages, thus reducing the life of the frequency converter.
Liquids can be carried through the air and condense in the frequency converter and may cause
corrosion of components and metal parts. Steam, oil, and salt water may cause corrosion of
components and metal parts. In such environments, use equipment with enclosure rating IP 55. As
an extra protection, coated printet circuit boads can be orded as an option.
Airborne Particles such as dust may cause mechanical, electrical, or thermal failure in the
frequency converter. A typical indicator of excessive levels of airborne particles is dust particles
around the frequency converter fan. In very dusty environments, use equipment with enclosure
rating IP 55 or a cabinet for IP 00/IP 20/TYPE 1 equipment.
In environments with high temperatures and humidity, corrosive gases such as sulphur, nitrogen, and
chlorine compounds will cause chemical processes on the frequency converter components.
Such chemical reactions will rapidly affect and damage the electronic components. In
such environments, mount the equipment in a cabinet with fresh air ventilation, keeping
aggressive gases away from the frequency converter.
An extra protection in such areas is a coating of the printed circuit boards, which can be ordered as an option.
NB!:
Mounting frequency converters in aggressive environments increases the risk of stoppages
and considerably reduces the life of the converter.
Before installing the frequency converter, check the ambient air for liquids, particles, and gases.
This is done by observing existing installations in this environment. Typical indicators of harmful
airborne liquids are water or oil on metal parts, or corrosion of metal parts.
Excessive dust particle levels are often found on installation cabinets and existing electrical installations. One
indicator of aggressive airborne gases is blackening of copper rails and cable ends on existing installations.
"Vibration and Shock
The frequency converter has been tested according
to a procedure based on the shown standards:
The frequency converter complies with requirements
that exist for units mounted on the walls and
floors of production premises, as well as in
panels bolted to walls or floors.
IEC/EN 60068-2-6: Vibration (sinusoidal) - 1970
IEC/EN 60068-2-64: Vibration, broad-band
random
"Control Principle
Afrequencyconverter rectifies AC voltage from mains into DC voltage, after which this DC voltage
is converted into a AC current with a variable amplitude and frequency.
The motor is supplied with variable voltage / current and frequency, which enables infinitely variable speed
control of three-phased, standard AC motors and permanent magnet synchronous motors.
"FC 300 Controls
The frequency converter is capable of controlling either the speed or the torque on the motor
shaft. Setting par. 1-00 determines the type of control.

Introduction to FC 300
Speed control:
There are two types of speed control:
•Speed open loop control which does not require any feedback (sensorless).
•Speed closed loop control in the form of a PID control that requires a speed feedback to an input. A
properly optimised speed closed loop control will have higher accuracy than a speed open loop control.
Selects which input to use as speed PID feedback in par. 7-00.
Torque control (FC 302 only):
Torque control is part of the motor control and correct settings of motor parameters are very
important. The accuracy and settling time of the torque control are determined from Flux
with motor feedback (par. 1-01 Motor Control Principle).
•Flux sensorless offers superior performance in all four quadrants at motor frequencies above 10 Hz.
•Flux with encoder feedback offers superior performance in all four quadrants and at all motor speeds.
The "Flux with encoder feedb" mode requires that an encoder speed feedback signal
is present. Select which input to use in par. 1-02.
Speed / torque reference:
The reference to these controls can either be a single refrence or be the sum of various references including
relatively scaled references. The handling of references is explained in detail later in this section.
"FC 301 vs. FC 302 Control Principle
FC 301 is a general purpose frequency converter for variable speed applications. The control
principle is based on space Voltage Vector Control (VVCplus).
FC 301 can handle asynchronous motors only.
The current sensing principle in FC 301 is based on sum current measurement in the DC link. The ground
fault protection on the motor side is solved by a de-saturation circuit in the IGBTs.
FC 302 is a high performance frequency converter for demanding applications. The
frequency converter can handle various kinds of motor control principles such as U/f special
motormode,VVCplusorFluxVectormotorcontrol.
FC 302 is able to handle Permanent Magnet Synchronous Motors (Brushless servo motors)
as well as normal squirrel cage asynchronous motors.
The current sensing principle in FC 302 is actually sensing the current in each motor phase. The advantage
of having a current transducer in each phase is to have full ground failure protection.
