|Publication Date:||1 January 2015|
Scope and Object
This technical report provides alternative methods for specifying ratings for adjustable speed electrical power drive systems (PDS) and, in particular, their basic drive modules (BDM).
It is not intended to cover adjustable speed drives for traction purposes.
General rules for rating specification for low voltage adjustable speed d.c. power drive systems are contained in IEC 61800-1, and for low voltage adjustable frequency a.c. power drive systems in IEC 61800-2.
