This part of GB 12668 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.
This part 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 a.c. supply voltages up to 1kV, 50Hz or 60Hz and a.c. drive systems with converter input voltages up to 35kV, 50Hz or 60Hz and output voltages up to 35kV.
Other parts of “Adjustable Speed Electrical Power Dive Systems” cover rating specifications, EMC, functional safety, etc.
The scope of this part 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 part 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.
