It incorporates the International Efficiency (IE) codes , allowing organizations to classify machines (IE1 to IE4) to meet global energy-saving regulations.
Common duty cycles defined include , S2 (short-time) , S3 (intermittent periodic) , and others up to S9. iec 60034-1 pdf free download
It classifies operational modes to help users select the correct machine for their application. These range from S1 (continuous duty) to S10 (duty with discrete constant loads and speeds) . It incorporates the International Efficiency (IE) codes ,
Sets limits for temperature rise based on insulation class (A, E, B, F, H). S3 (intermittent periodic)
