3.1.4:
3.1.1
basic drive module
BDM
electronic power converter and related control, connected between an electric supply and a
motor. The BDM is capable of transmitting power from the electric supply to the motor and
may be capable of transmitting power from the motor to the electric supply. The BDM controls
some or all of the following aspects of power transmitted to the motor and motor output:
• current;
• frequency;
• voltage;
• speed;
• torque;
• force;
• position

CDM
drive module consisting of, but not limited to, the BDM and extensions such as protection
devices, transformers and auxiliaries. However the motor and the sensors which are
mechanically coupled to the motor shaft are not included
3.1.3
power drive system
PDS
system consisting of one or more complete drive module(s) (CDM) and a motor or motors.
Any sensors which are mechanically coupled to the motor shaft are also part of the PDS;
however the driven equipment is not included

installation
equipment or equipments which include at least both the PDS and the driven equipment

3.3 Location, ports and interfaces
3.3.5
port for process measurement and control
Delete, in the existing definition, the existing words "as defined in Clause 3 (see Figure 2)".
3.3.9
mechanical link
Delete, in the existing definition, the existing words "as defined in Clause 3".

3.4 Components of PDS
3.4.2
(electric) motor
Add, after the existing definition and source, the following new note:
NOTE For the purposes of this standard, the motor includes all sensors which are mounted on it and which are
relevant for supporting the operating mode and interacting with a CDM.
Delete the existing definition 3.4.3 and renumber the existing definition 3.4.4 as 3.4.3.
Add, after definition 3.4.3, the following new subclause 3.5 and the following new terms and
definitions 3.5.1 to 3.5.4 as follows:
3.5 Phenomena-related definitions
3.5.1
voltage deviation
difference, generally expressed as a percentage, between the voltage at a given instant at a
point in the system, and a reference voltage such as: nominal voltage, a mean value of the
operating voltage, declared supply voltage
[IEV 604-01-17]
61800-3 Amend. 1 © IEC:2011 – 5 –
3.5.2
voltage change
variation of the r.m.s. or peak value of a voltage between two consecutive levels sustained for
definite but unspecified durations
NOTE Whether the r.m.s. or peak value is chosen depends upon the application, and which is used should be
specified.
[IEV 161-08-01]
3.5.3
voltage fluctuation
series of voltage changes or a continuous variation of the r.m.s. or peak value of the voltage
NOTE Whether the r.m.s. or peak value is chosen depends upon the application, and which is used should be
specified.
[IEV 161-08-05]
3.5.4
voltage dip
sudden reduction of the voltage at a point in an electrical system followed by voltage recovery
after a short period of time from a few cycles to a few seconds
[IEV 604-01-25, IEV 161-08-10]
4.2.1 Conditions
Renumber the existing note of this subclause as Note 1.
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.

– 6 – 61800-3 Amend. 1 © IEC:2011
5.1 General conditions
5.1.1 Acceptance criteria (performance criteria)
Add, after the last existing paragraph, the following new paragraph:
Subclauses 5.2 and 5.3 state the acceptance criterion required for each phenomenon.
5.2 Basic immunity requirements – low-frequency disturbances
5.2.1 Common principle
Delete the existing Note 3.
5.2.2.1 Low voltage PDSs – (voltage distortion)
Replace the existing paragraph, note and Table 2 of this subclause, by the following new
paragraph, new note and new Tables 23, 24 and 25:
The BDM, CDM or PDS shall sustain the immunity levels while meeting the performance
criteria given in Tables 23, 24 and 25. It shall be verified that these levels will not cause the
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.
