EN50598 Energy Efficiency

CDM - Complete Drive Module

CDM Complete Drive Module

The CDM - Complete Drive Module – contains the drive controller as well as auxiliary devices and input components. The efficiency classes IE0 to IE2 of the drive controller that are specified in IEC 61800-9-2 (EN 50598-2) refer to the 90;100 operating point, i.e. 90 % motor stator frequency and 100 % torque current. The reference drive controller has the efficiency class IE1. The following table shows the losses of a reference CDM (efficiency class IE1) according to IEC 61800-9-2 (EN 50598-2).
