3.7 Energy Efficiency

The standard EN 50598 Ecodesign for power drive systems, motor starters, power electronics and their driven applications
provides guidelines for assessing the energy efficiency of frequency converters.
3 3 The standard provides a neutral method for determining efficiency classes and power losses at full load and at part load.
The standard allows combination of any motor with any frequency converter.

3.7.1 IE and IES Classes

Complete drive modules
According to the standard EN 50598-2, the complete drive
module (CDM) comprises the frequency converter, its
feeding section, and its auxiliaries.
Energy efficiency classes for the CDM:
•
IE0 = below state of the art.
•
IE1 = state of the art.
•
IE2 = above state of the art.
Danfoss frequency converters fulfill energy efficiency class
IE2. The energy efficiency class is defined at the nominal
point of the CDM.
Power drive systems
A power drive system (PDS) consists of a complete drive
module (CDM) and a motor.
Energy efficiency classes for the PDS:
•
IES0 = Below state of the art.
•
IES1 = State of the art.
•
IES2 = Above state of the art.

Danfoss VLT frequency converter typically fulfill energy
efficiency class IES2.
The energy efficiency class is defined at the nominal point
of the PDS and can be calculated based on the CDM and
the motor losses.
