  • SCOPE

    1 Scope

    This part of IEC 61800 specifies requirements for adjustable speed power drive systems, or their elements, with respect to electrical, thermal and energy safety considerations. It does not cover the driven equipment except for interface requirements. It applies to adjustable speed electric drive systems which include the power conversion, drive control, and motor or motors. Excluded are traction and electric vehicle drives. It applies to d.c. drive systems connected to line voltages up to 1 kV a.c., 50 Hz or 60 Hz and a.c. drive systems with converter input voltages up to 35 kV, 50 Hz or 60 Hz and output voltages up to 35 kV.

    Other parts of IEC 61800 cover rating specifications, EMC, functional safety, etc.

    The scope of this part of IEC 61800 does not include devices used as component parts of a PDS if they comply with the safety requirements of a relevant product standard for the same environment. For example, motors used in PDS shall comply with the relevant parts of IEC 60034.

    Unless specifically stated, the requirements of this International Standard apply to all parts of the PDS, including the CDM/BDM (see Figure 1).

    NOTE In some cases, safety requirements of the PDS (for example, protection against direct contact) can necessitate the use of special components and/or additional measures.

    1DV.1 Modification to add the following:

    DV.1.1 This document is only applicable to the power conversion and drive control equipment, servo drives and integral servo drive/motor combinations.

    DV.1.2 Only devices connected to line voltages of up to 1,5 kV a.c. are covered.

    DV.1.3 A component of a product covered by this standard shall comply with the requirements for that component. See Annex dva for a list of additional standards covering components used in the products covered by this standard.

    1DV.2 Modification to add the following:

    This equipment is for use in ordinary locations in accordance with Articles 430 and 440 of the National Electrical Code, NFPA 70.

    1DV.3 Modification to add the following:

    Specifications provided in other parts of the 61800 Series of Standards (for example EMC in part 3) apply only on agreement between the manufacturer and the customer.
