Determining Efficiency Class for a PDS System

How is the efficiency class of the PDS-System determined?

The efficiency class of the system is determined by adding the losses of the CDM and motor at the operating point 100; 100, i.e. 100 % speed and 100 % torque. The IES class can then be read from the table.
