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).

Reference values according to IEC 61800-9-2 (EN 50598-2)


The operating points differ from the requirements of the EU Regulation (EU) 2019/1781. For this reason, Bauer will only provide the data of the operating points according to (EU) 2019/1781 in the future.
