AA.4.1 General
Where electronic equipment is used, it should be designed to withstand at least values specified in Table A.1“Machine tools immunity tests – Enclosure port”, Table A.2“Machine tools immunity tests – Ports for signal ports”, Table A.3“Machine tools immunity tests – DC input and output power ports”, Table A.4“Machine tools immunity tests – AC input and output power ports” and Table A.5 “Machine tools immunity tests 一Functional earth port” in Annex A of EN 50370-2:2003.
AA.4.2 Performance criteria
The assessment of performance degradation used during and/or at the conclusion of the tests,should be simple, but at the same time give adequate proof that the essential functions of the machine tool are operative. The performance criteria should be used to check the performance of a machine tool or modules against external disturbances.Since machine tools and their modules represent a very broad and inhomogeneous group of products, a precise definition of performance criteria cannot be given.
Nevertheless a functional description and a definition of performance criteria and monitoring methods, during or as a consequence of the EMC testing， should be specified by the manufacturer and included in the test report, based on the general criteria and examples of malfunctioning contained in Table 2 “Performance criteria definition” of EN 50370-2:2003, which cannot be considered exhaustive.
It is the responsibility of the manufacturer to define the representative parameters for each specific performance and the permissible degradation of performance or loss of function of the machine tool or the module(s). Table AA.7 classifies the effects of a given disturbance into three performance criteria: A, B and C, each of which defines a specified level of performance.
NOTE Alternatively, IEC 61000-6-2:2005, Clause 4, criterion A) or B) can be used.
A numerical control system consists of numerical controller, power drive system, PLC, sensors, etc. A detailed component list with relevant standards (e.g. amongst others IEC 61 800-5-1 for safety requirements for power drive system, IEC 60034-1 for motors, IEC 61010-2-201 or IEC 61131-2 for PLC) is given in Annex FF. Annex BB is provided for general guidance. It should be taken into consideration that the actual requirements in the latest edition of the relevant standards can be different and should be complied with.
