Overview

IEC 61800-3:2004/AMD1:2011 is an important amendment to the international standard IEC 61800-3, which focuses on adjustable speed electrical power drive systems with specific emphasis on electromagnetic compatibility (EMC) requirements and test methods. Developed by the International Electrotechnical Commission (IEC), this amendment updates the EMC provisions ensuring that variable speed drives operate reliably within their electromagnetic environment while minimizing electromagnetic disturbances.

This standard amendment defines enhanced EMC immunity and emission levels, introduces comprehensive definitions related to power drive systems (PDS), and specifies rigorous test methods to validate compliance with EMC requirements. It is applicable to both low- and high-voltage drive systems and addresses performance criteria across different industrial environments.

Key Topics

EMC Requirements for Power Drive Systems

• Emission categories and immunity classes are defined to ensure that adjustable speed drives do not produce intolerable electromagnetic disturbances and are sufficiently immune to disturbances present in industrial environments.
• Amendment 1 updates the minimum immunity levels for low-frequency conducted disturbances, harmonics, commutation notches, voltage dips, voltage deviations, and short interruptions.
• It distinguishes between first environment (less demanding electromagnetic environment) and second environment (more demanding industrial settings), setting different immunity and emission criteria for each.

Detailed Definitions of Drive System Components

• Introduces clarity on key components such as:
  • Basic Drive Module (BDM): The core electronic power converter controlling power transmission to the motor.
  • Complete Drive Module (CDM): Encompasses BDM plus extensions like transformers and protection devices (excluding motor and sensors).
  • Power Drive System (PDS): One or more CDMs combined with motors and their associated mechanical shaft sensors.
  • Installation: The full setup including PDS and the driven equipment.

Specific EMC Test Methods

• Prescribes how to verify immunity to harmonics, voltage dips, and short interruptions using both analytical and test-based approaches.
• Specifies the use of standard measurement techniques such as IEC 61000-4 series for testing voltage dips and harmonics.
• Details the test conditions, e.g. PDS being connected to a motor recommended by the manufacturer or using a passive test load under defined conditions.
• Performance criteria categorize equipment response to disturbances ensuring reliability in industrial operations.

Documentation Requirements

• Manufacturers are required to provide comprehensive installation and operation documentation, including:
  • Emission warnings for different categories.
  • Immunity limitations, especially if the system is used in the “second environment” where EMC disturbances are higher.

Applications

The IEC 61800-3 amendment is critical for industries that rely on adjustable speed drives for motor control such as:

• Manufacturing plants with variable-speed conveyor systems and robotics.
• Renewable energy installations using power drives for wind turbines and solar tracking systems.
• Process industry applications requiring precise motor control under variable load and environmental conditions.
• Automation systems in factories where EMC disturbances can affect device performance and safety.
• Transportation sectors employing electric drives in railways and electric vehicles.

Compliance with the updated EMC requirements ensures:

• Minimization of electromagnetic interference with neighboring equipment.
• Enhanced operational reliability and longevity of power drive systems.
• Reduced downtime and maintenance costs due to EMC-related faults.

Related Standards

• IEC 61000 series: Core EMC standards referenced within the amendment, including:
  • IEC 61000-2-4: Compatibility levels in industrial plants for low-frequency conducted disturbances.
  • IEC 61000-4-11, IEC 61000-4-13, IEC 61000-4-34: Testing and measurement techniques for voltage dips, harmonics, and voltage variation immunity.
• IEC 60146-1-1: Pertains to semiconductor converter requirements referenced in commutation notch testing.
• IEC 61800 series: Other parts covering mechanical, electrical, and operational aspects of adjustable speed electrical power drive systems.

Adhering to IEC 61800-3:2004/AMD1:2011 guarantees compliance with globally recognized best practices for EMC in power electronics, supporting safe and efficient industrial automation and motor control applications.

Replace the existing third paragraph of this subclause by the following new paragraph and
new Note 2:
For the tests, the CDM shall be connected to a motor recommended by the manufacturer with
a cable and earthing rules defined by the manufacturer. Alternatively, a passive test load
(resistive, or resistive and inductive) may be applied (for example, for evaluation of the low-
frequency emissions), if permitted by the manufacturer.
NOTE 2 For high frequency emissions, because it is necessary to simulate differential and common mode
capacitances and couplings, a passive test load may not be suitable for this application.
4.3 Documentation for the user

Replace the existing second paragraph of this subclause by the following new paragraph and
new Notes 1 and 2:
The manufacturer shall supply the documentation necessary for the correct installation of a
BDM, CDM or PDS into a typical system or process in the intended environment. This
information includes any emission warnings required by 6.1 and Table 13. It also includes the
warnings required by 5.3.2 in the case where the immunity of a BDM, CDM or PDS is not
suitable for the second environment.
NOTE 1 From the emission point of view, a PDS (or BDM or CDM) with a lower emission category, such as C1,
can always be used instead of one with a higher emission category, such as C3.
NOTE 2 Emission categories are independent of immunity. For example, a statement that a PDS has emission
category C1 does not imply that the immunity is only suitable for the first environment.

ratings for the input circuits (filters, etc.) to be exceeded. Analysis of commutation notches
shall be in the time domain. The manufacturer may verify immunity by calculation, simulation,
or test, according to 5.2.1. If the chosen verification method is by test, it shall be performed
using the PDS with the motor connected. For equipment rated below 16 A per phase, the test
method of IEC 61000-4-13 can be applied.
NOTE Frequency domain analysis of the contribution from notches to the total harmonic distortion will not fully
account for harmful effects, see B.1.

Replace, in the second paragraph, the existing words "is an equipment within the scope" by
“within the scope".
Add, at the end of this subclause, the following new subclause 6.2.3.2:
6.2.3.2 Low-voltage public supply network – Equipment covered by IEC 61000-3-12
When a PDS is within the scope of IEC 61000-3-12, the requirements of that standard apply.
However, when one or more PDSs are included in equipment within the scope of
IEC 61000-3-12, the requirements of that standard apply to the complete equipment and not
to the individual PDS. It is the responsibility of the equipment manufacturer to define the
boundary of the system or sub-system to which IEC 61000-3-12 applies, and the method
which demonstrates compliance of the equipment.
6.2.3.2 Low-voltage public supply network – Equipment not covered by IEC 61000-3-2
Renumber the existing subclause 6.2.3.2 as 6.2.3.3.
Add, at the end of the existing title of this subclause, the words "or IEC 61000-3-12".
Replace, in the existing first sentence of this subclause, the words "by IEC 61000-3-2,
(example: rated current above 16 A)" by "IEC 61000-3-2 or IEC 61000-3-12 (rated current
above 75 A),".
This instruction applies to the French text only.
Replace, in the fourth existing paragraph of this subclause, the words "shall be used" by
"should be used".

Replace, in the first paragraph of this subclause, the existing words "a PDS is equipment
within the scope" by "a PDS is within the scope ".
Replace, in the second paragraph of this subclause, the existing words "a PDS is an
equipment within the scope" by "a PDS is within the scope ".
Add, after the existing text of this subclause, the following new note:
NOTE Application of the voltage fluctuation limits of IEC 61000-3-3 and 61000-3-11 is only possible when the
characteristics of the load provided by the driven equipment are known. For that reason, only the machine builder
and/or end user are capable of characterizing compliance with regard to the voltage fluctuation limits.
6.2.4.3 PDSs of rated voltage above 1 000 V
Replace the existing title and text of this subclause by the following new title and text:
6.2.4.3 PDS not in the scope of IEC 61000-3-3 and IEC 61000-3-11
For equipment not in the scope of IEC 61000-3-3 and IEC 61000-3-11 emissions of voltage
fluctuations are generally dependent on the loading conditions and this standard cannot give
requirements.
NOTE Local rules given by local authorities can apply to the complete installation.
