Parameters Meaning
Forward and return
seam
• The return seam is symmetrical to the forward seam using
the cutting length as an axis of symmetry.
Buttonhole width =
tacking width
• The buttonhole width setting automatically specifies the tack-
ing width. The tacking width can be adjusted via the parame-
ters offset l and offset r in the relevant tacking menu.
Tacking • The final tacking length is the first tacking length if both tack-
ings are identical. The tacking length is set for both in the
menu First tacking.
Buttonhole length • The total buttonhole length is determined by the cutting
length + length before cut + length after cut + first tacking
length + final tacking length.
