Adjustable speed electrical power drive systems - Part 5-2: Safety requirements. Functional: Part 5-2 of the standard series EN 61800 is a product standard for electrical drive systems with integrated safety functions. It defines the functional safety requirements for developing safe drives in accordance with the standard EN/IEC 61508. It applies to adjustable speed electrical power drive systems, as well as servo and frequency converters in general, which are dealt with in other parts of the standard series EN 61800.
EN 61800-5 Part 2: General requirements - Rating specifications for low voltage adjustable frequency a.c. power drive systems, lists a series of new terms, which are explained in greater detail below:
Power drive system (PDS)
System comprising power equipment (power converter module, AC motor, feed module, ...) and control equipment. The hardware configuration consists of a complete drive module (CDM) plus a motor or motors with sensors, which are mechanically connected to the motor shaft (the driven equipment is not included).
PDS/Safety-related (SR)
AC power drive system for safety-related applications.
Complete drive module (CDM)
Drive system without motor and without a sensor connected mechanically to the motor shaft; it comprises, but is not limited to, the BDM and expansions such as the feed module and auxiliary equipment.
Basic drive module (BDM)
Drive module consisting of a power converter module, control equipment for speed, torque, current, frequency or voltage and a control system for the power semiconductor components, etc.
