4.2 EMC Compliant Installation

4.2.1 General Aspects of EMC Emissions

The frequency converter, motor cable and the motor generate airborne interference in the range 30 MHz to 1 GHz. Capacitive currents in the motor cable coupled with a high dU/dt from the motor voltage generate leakage currents.

Use screened motor cable to reduce radiated interference. Connect the motor cable screen to the frequency converter enclosure as well as to the motor enclosure. Use integrated screen clamps to avoid twisted screen ends (pigtails).

To reduce the interference level from the entire system (unit + installation), make motor and brake cables as short as possible. Avoid placing cables with a sensitive signal level alongside motor and brake cables. Especially control electronics generate radio interference higher than 50 MHz (airborne).

Table 4.1

Illustration 4.9 Situation that Generates Leakage Currents

Ensure that screen currents can be conveyed back to the frequency converter. Also, ensure good electrical contact from the mounting plate through the mounting screws to the frequency converter chassis.

NOTICE

When unscreened cables are used, some emission requirements are not complied with, although the immunity requirements are observed.

sinusoidal current is transformed with a Fourier analysis and split into sine-wave currents with different frequencies,

that is, different harmonic currents In with 50 Hz basic frequency:

Hz 50 250 350

Table 4.4 Harmonic Currents

The harmonics do not affect the power consumption directly, but increase the heat losses in the installation (transformer, cables). So, in plants with a high percentage of rectifier load, maintain harmonic currents at a low level to avoid overload of the transformer and high temperature in the cables.

Illustration 4.10 Harmonic Currents

NOTICE

Some of the harmonic currents might disturb communication equipment connected to the same transformer or cause resonance with power-factor correction batteries.

To ensure low harmonic currents, the frequency converter is equipped with intermediate circuit coils as standard. This normally reduces the input current I

by 40%.

To ground electrical equipment properly, follow

•

all local and national electrical codes Proper protective earthing for equipment with

•

ground currents higher than 3.5 mA must be established, see chapter 4.4.1.1 Ground Leakage

Current

A dedicated ground wire is required for input

•

power, motor power and control wiring Use the clamps provided with the equipment for

•

proper ground connections Do not ground one frequency converter to

•

another in a “daisy chain” fashion Keep the ground wire connections as short as

•

possible Use of high-strand wire to reduce electrical noise

•

is recommended Follow motor manufacturer wiring requirements

Ground Leakage Current

4 4

Illustration 4.11 Cable Length and Power Size Influence on Leakage Current. Pa > Pb.

Follow national and local codes regarding protective earthing of equipment with a leakage current > 3.5 mA. Frequency converters generate a leakage current in the ground connection. A fault current in the frequency converter at the output power terminals might charge the filter capacitors and cause a transient ground current. The ground leakage current depends on various system configurations including RFI filtering, screened motor cables, and frequency converter power.

MG34X102 - Rev. 2013-12-04 15

Illustration 4.12 Line Distortion Influences Leakage Current

According to EN/IEC 61800 5 1, ground wire must be reinforced, if the leakage current exceeds 3.5 mA:

Ground wire (terminal 95) of at least 10 mm2 [8

•

AWG] 2 separate ground wires both complying with the
