3.7 Energy EfficiencyThe standard EN 50598 Ecodesign for power drive systems, motor starters, power electronics and their driven applicationsprovides guidelines for assessing the energy efficiency of frequency converters.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.Extended productMotor systemDrive system (PDS)Complete drive module (CDM)Infeedsection Auxiliaries Auxiliaries MotorMotor startercontactors, soft starters, ...Motor control system = CDM or starterDriven equipmentTrans-missionLoadmachineBasicdrivemodule(BDM)Mainsandmainscable130BE604.11Illustration 3.14 Power Drive System (PDS) and Complete Drive Module (CDM)3.7.1 IE and IES ClassesComplete drive modulesAccording to the standard EN 50598-2, the complete drivemodule (CDM) comprises the frequency converter, itsfeeding 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 classIE2. The energy efficiency class is defined at the nominalpoint of the CDM.Power drive systemsA power drive system (PDS) consists of a complete drivemodule (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.Depending on the motor efficiency, motors driven by aDanfoss VLT® frequency converter typically fulfill energyefficiency class IES2.The energy efficiency class is defined at the nominal pointof the PDS and can be calculated based on the CDM andthe motor losses.System Integration VLT® DriveMotor FCP 106/FCM 10644 Danfoss A/S © 06/2016 All rights reserved.
