" CE Conformity and Labeling

What is CE Conformity and Labeling?

The purpose of CE labeling 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.

Adjustable fre quency drives are regulate d by three EU directives:

The machinery directive (98/37/EEC)

All machines with critical moving p arts are covered by the m achinery directive of January 1, 1995. Since an

adjustable frequency drive is largely electrical, it does not fall under the m achinery directive. However, if

13

MG.33.B3.22 - VLT is a registered Danfoss trademark

FC 300 Design Guide

Introduction to FC 300

an adjustable frequency drive is supplied for use in a machine, we provide information on safety aspects

relating to the adjustable frequency drive. We do this by means of a manufacturer’s declaration.

The low-voltage directive (73/23/EEC)

Adjustable frequency drives must be CE- labe led in accordance with the low-voltage d irective of

January 1, 1997. The dire ctive applies to all electrical equipment and appliances used in the

50 - 1000 V AC and the 75 - 1500 V DC voltage ranges. Da nfoss CE-labels in accordance with

the directive and issues a d eclaration of conformity upon request.

The EMC directive (89/336/EEC)

EMC is short for electromagnetic compatib ility. The presence of electrom agnetic compatibility means that the

mutual interference between different com p onents/appliances does not affect the way the appliances work.

The EMC directive came into effect January 1, 1996. Danfoss CE-labels in acco rdance with the directive and

issues a declaration of conformity upon request. To c arry out EMC-correct installation, see the instructions in

this Design Guid e. In addition, we specify which standards our products comply with. We offer the f

ilters

presented in the specifications and provide other typ es of assistance to ensure the op timum EMC result.

The adjustable freque ncy drive is most often used by professionals of the trade as a complex component

forming part of a larger appliance, system or installation. I t must be noted that the responsibility for

the final EMC properties of the appliance, system, or installati on lies with th

einstaller.

" What Is Covered

The EU "Guideline s on the Ap plication of Council Directive 8 9/336/EEC" outline three typical situations

of using an adjustable frequency drive. See following for EMC coverage and

CE labeling.

1. The adjustable frequency drive is sold directly to the end consu

mer. The adjustable frequency drive is

for example sold to a DIY market. The end consumer is a layman. He installs the adjustable frequency

drive himself for use with a hobby machine, a kitchen appliance, etc. For such applications, the

adjustable frequency drive must be CE-labeled in accordanc

e with the EMC directive.

2. The adjustable frequency drive is sold for installation in a p lant. The plant is built up by professionals of the

trade. It could be a production plant or a heating/ventilation pla nt de signed and installed by professionals

of the trade. Ne ither the adjustable frequency driv

e nor the finished plant must be CE-labeled under the

EMC d irective. How ever, the unit must comp ly with the basic EMC requirements of the d irective. This is

ensured by using components, applia nces, and systems that are CE-labeled under the EMC directive.

3. Theadjustablefrequencydriveissoldaspartofac

ompletesystem. Thesystemisbeingmarketed

as complete and could be e.g. an air conditioning system. ThecompletesystemmustbeCE-labeled

in accordance with the EMC directive. The m anufacturer can ensure CE la beling und er the EMC

directive either by using CE -labeled comp

onents or by testing the EMC of the sys tem. If it chooses

to use only CE-labeled components, it does not have to test the entire system.

" Danfoss VLT Adjustable Frequency

Drive and CE L abeling

CE labeling is a positive feature when used for its original purpose, i.e. to facilitate trade within the EU and EFTA.

However, CE labeling may cover many different specifications. Thus, you must check

what a given CE labe l specifically covers.

The covered specifications can be very diffe rent and a C E label may therefore give the installer a false sense

of security when using an adj

ustable frequency drive as a component in a system or an appliance.

Danfoss CE labels the adjust

able frequency drives in accordance w ith the low-voltage directive.

This means that if the adjustable frequency drive is installed correctly, we guarantee compliance

14

MG.33.B3.22 - VLT is a registered Danfoss trademark

FC 300 Design Guide

Introduction to FC 300

with the low-voltage directive. Danfoss issues a d ecla ration of conformity that confirms our

CE labeling in accordance with the low-voltage directive.

The CE label also ap plie s to the EM C 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 d etailed inst ructions for installation to ensure EMC-correct installation.

Furthermore, Danfoss specifies which our diffe rent produ cts com pl y with.

Danfoss gladly provides other types of assistance that can help you obtain the bes t EMC r esult.

" Compliance with EMC Directive 89/336/EEC

As mentioned, the adjustable frequency drive is m ostly used b y professionals of the trade as a complex

component forming part of a larger appliance, system, or installation. It mus t be noted t

hat the

responsibility for the final EMC properties of the applianc e, system, or installation lies with the installer.

As an aid to the installer, Danfoss has prepare d EMC installat ion guidelines for the Power Drive System.

The standards and test levels state d for Power Drive Systems are compl i

ed with, provided that the

EMC-correct instructions for installation are followed, see s ection Electrical Installation.

A Cold plate technology

The adjustable frequency drive is built upon a very stable aluminum 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 adjustable frequency drive, where a

majority of t he heat losses dissipates from the electronics to an external cooling surface.

The built-in DC coil ensures low harmonic disturbance of the power supply according to IEC-1000-3-2.

C Air guiding shield

The shield allows cold air to pass by the electronics only. The plastic air guide shield is enclosed in

the package and is easily snapped in place. If the adju stable frequency drive is to operate as a

cold plate drive, the air guiding shield is inserted in the cooling channel through the bottom of the

drive if it is snapped onto the fan. Thus, the amount of heat transferred to t he surroundings via the

cooling air from the fan is reduced.

D Snap-off fan

Like most of th e elements, the fan can eas ily be r e moved for easy cleaning and r emounted .

E Safe Stop

The adjustable frequency drive comes standard with the safe stop functionality for stop category 0

(EN 60204-1) with safety category 3 (EN 954-1) installations. This feature prevents the drive from

starting unintentionally.

F Control signals

Spring-loaded cage clamps contribute to reliability and facilitate easy commissioning and service.

G Options

Options for bus communication, I/O extension etc. can be delivered or ordered built-in from the

factory. Options mounted under the LCP are referred to as option Slot A (top) and option Slot B

(bottom). Option C (see under K Freely programm able option is moun ted on the side of the drive,

while option D is m ounted underneath the control cable decoupling clamps.

H Local Control Panel

The LCP 102 has a graphical user interface. Choos e b etwee n six b uilt-in languages (including Chinese)

or have it customized with your own languages and phrases. Two of the languages can be changed

by the user.

Additionally a simple version, LCP 101, is available with an alpha- n umeric display. A complete

programming of FC 302 can be handled by both LCP’s.

J Hot-pluggable 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 w ith the MCT-10 set-up s oftware.

" Air Humidity

The adjustable fre quency drive has bee n designed to meet the IEC/EN 60068 -2-3 standard,

EN 50178 pkt. 9.4.2.2 at 122 °

F(50°C).

" Aggressive Environments

An adjustable frequency drive contains a large number of mechanical and electronic components.

All are to some extent vul

nerable to environmental effects.

Introduction to FC 300

The adjustable frequency drive should not be installed in environments with airborne

liquids,particles,orgasescapableofaffecting a nd damaging the e lectronic c omponents.

Failure to take the necessary p rotective measure s increases the risk of stoppages,

thus reducing the life of the adjustable frequency drive.

L

iquids can be carried through the air and condense in the adjustable frequency drive and may cause

corrosion of components and metal part s. Steam, oil, and salt water may cause corrosion of components

and metal parts. In such environments, use equipment with enclosure rating IP 55 (NEMA 12). As

an extra protection, coated printed circuit boards can be ordered as an option.

Airborne P

articles such as dust may cause mechanical, electrical, or the rmal failure in the adjustable

frequency drive. A typical indicator of excessive levels of airborne particles is dust particles a round

theadjustablefrequencydrivefan. Inverydusty environments, use equipment with encl

osure rating

IP 55 (NEMA 12) or a cabinet for IP 00/IP 20/TYPE 1 (NEMA 1) equipment.

In environments with high temperatures and humidity,

corrosive gases such as sulfur, nitrogen, and chlorine

compounds will cause chemical processe s on the adjustable frequency drive components.

Such chemical reactions will rapidly affect and damage the electronic components. In

such environments, mount the eq uipment in a cabinet with fre sh a ir ven

tilation, keeping

aggressive gases away from the adjustable freque nc y drive.

An extra protection in such areas is a coating of the printed circuit boards, which can be ordered as an option.

NOTE

Mounting adjus table frequency drives in aggres sive envi

ronments increases the risk of

stoppages and considerably red uces the life of the drive.

Before installing the adjustable frequency drive, check the ambien t air for liquids, particles, and g ases.

This is done b y observing existing installations in this environment. Typical indicators of harmful

airborne liquids are water or oil on metal parts, or co

rrosion 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 e x isting installations.

" Vibration and Shock

The adjustabl e frequency drive has been

tested according to a procedu

re based on

the shown standards:

The adjustable frequency drive complies with

requirements that exist for units mounted on the

wallsandfloorsofproduc

tion premises, as well

as i n 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

An ad justable frequency drive rectifies AC voltage from line into DC voltage, after w hich this DC

voltage is converted into an AC current with a variable amplitude and frequency.

The motor is supplied with variable voltage / current and f re quency, which enables infinitely variable speed

control of three-phased, standard AC motors and permanent magnet synchronous motors.

" FC 300 Controls

The adjustable frequency drive is capable of controlling either the speed or the torque on the

motor shaft. Setting par. 1-00 determines the type of control.

S

peed control:

There are two types of speed control:

• Speed open lo op control which do es not require any feedback.

• Speed closed-loop control in the form of a PID control that requires a speed feedback to an input. A

properly optimized speed closed-loop control will have higher accuracy than a speed open loop control.

Selects which terminal to use as speed PID feedback in par. 7-00.

T

orque control:

Torque co ntrol is part of the motor control and correct settings of motor parameters are very

important. The accuracy and settling time o f the torque control are determine d 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 terminal to use in par. 1-02.

S

peed / torque refere nce:

The reference to these controls can either be a single refere nce or th e sum

of various references including

relatively scaled references. T h e handling of references is explained in detail later in this section.

open loop and closed-loop confi gurations:

In the configuration shown in the illustration above, par. 1-01 Motor C ontrol Principle is set to "VVC

plus

[1]" and par. 1-00 is set to "Speed open loop [0]". The resulting reference from the reference handling

system is received and fed through the ramp limitation and speed limitation before being sent to the motor

control. The output of the motor control is then limited by the maximum frequency limit.

If par. 1-0 0 is set to "Speed closed-loop [1]", the result ing reference will be passed from

the ramp li mitation and speed limitation into a sp ee d PID control. The Spe ed PID control

parameters are located in the par. group 7-0*. The resulting reference from the Speed P ID

control is sent to the m otor control limited by the frequency limit.

Select "Process [3]" in par. 1-00 to use the process P ID control for closed-loop control of e.g. speed

or pressure in the controlled appl ication. The Process PID parameters are located in par. group

7-2* and 7-3*. Process PID is not available in this software release.
