PDS secondo le IEC 61800-n

IEC 61800-1 System 2.1.1 Power drive system (PDS) (see figure 1) System consisting of power equipment (composed of converter section, d.c. motor and other equipment such as, but not limited to, the feeding section or the field supply), and control equipment (composed of switching control - on/off for example - speed control, current control, firing system, field control, protection, status monitoring, communication, tests, diagnostics, process interface/port, etc.)

IEC 61800-2 2.1.1 A.C. power drive system (PDS) (see figure 1) System consisting of power equipment (composed of converter section, a.c. motor and other equipment such as, but not limited to the feeding section), and control equipment (composed of switching control – on/off for example –, voltage, frequency, or current control, firing system, protection, status monitoring, communication, tests, diagnostics, process interface/port, etc.).

IEC 61800-3 3.1 Overview For the purposes of this document, definitions related to EMC and to relevant phenomena to be found in IEC 60050(161), in CISPR, and also, the following additional definitions apply. A power drive system (PDS) consists of a motor and a complete drive module (CDM). ...

... IEC 61800-3 It does not include the equipment driven by the motor. The CDM consists of a basic drive module (BDM) and its possible extensions such as the feeding section or some auxiliaries (e.g. ventilation). The BDM contains converter, control and self-protection functions. Figure 1 shows the boundary between the PDS and the rest of the installation and/or manufacturing process. IEC 61800-1, IEC 61800-2 and IEC 61800-4 give details for these definitions.

IEC 61800-4 3.1.1 A.C. power drive system (PDS) with voltage above 1 kV (see figure 1) System consisting of: power equipment (possible harmonic filters, input transformer, converter section, possible output transformer, a.c. motor); control, protection and auxiliaries.

IEC 61800-5-1 3.20 power drive system PDS system for the speed control of an electric motor, including the CDM and motor but not the driven equipment (see Figure 1)

IEC 61800-5-2 .11 PDS(SR) adjustable speed electrical power drive system suitable for use in safety-related applications

IEC TR 61800-6 2.1 Terms and definitions For the purpose of this technical report the definitions given in IEC 61800-1, IEC 61800-2 and IEC 60146-1-1 as well as the following, apply.

IEC TR 61800-8 3.1 Overview of the system A power drive system (PDS) consists of a motor and a complete drive module (CDM). It does not include the equipment driven by the motor. The CDM consists of a basic drive module (BDM) and its possible extensions such as the feeding section or some auxiliaries (e.g. ventilation). ......

IEC TS 61800-8 The BDM contains converter, control and self-protection functions. Figure 1 shows the boundary between the PDS and the rest of the installation and/or manufacturing process. If the PDS has its own dedicated transformer, this transformer is included as a part of the CDM.
