Abstract
Identification elements for identifying the size, shape, and kind of embroidery frame ( ) are installed on the embroidery frame ( ) for a sewing or embroidery machine with an embroidery module ( ). Furthermore, at least one reference cam ( ) is provided on the embroidery frame ( ), and by means thereof the precise position of the embroidery frame ( ) relative to the embroidery module ( ), and thus also relative to the needle ( ), can be derived. By a comparison of the actual position of the embroidery frame ( ) with the desired position, a fault can be detected and a new positioning of the embroidery frame ( ) can be performed in the case, for example, that switching steps of the drive element in the embroidery module ( ) have been lost.
