At higher field weakening speedssupplementary short codes are required: "C05" forn F >1.15⋅ n N to 1.7 ⋅ n N and "C06" for n F >1.7⋅ n N(short codes: from Page 3/118).The motors can be operated at rated output P N up to the fieldweakening speed n Fmax .For speeds > n Fmax , the output must be reduced (see CatalogPart 2 under "Field control range" and "Speed data on the ratingplate").Rated field voltageFor other rated field voltages and the associated Order No. supplement,see Page 3/6.Type of constructionFor other types of construction and the associated Order No.supplement, see Page 3/6.3/20Siemens DA 12 · 2008
