PDS - Power Drive System

A PDS or Power Drive System consists of a CDM – Complete Drive Module – and a motor. EN 50598-2 defines Reference Power Drive Systems that are based on a 4-pole reference motor of efficiency class IE2 and a Reference CDM with 400 V. The efficiency classes IES 0 to IES 2 refer to the operating point 100; 100, i.e. 100 % speed and 100 % torque. The reference values according to EN 0598-2 are given in the following table.
