Adjusting the stitch length correction factor
Depending on the sewing material, the stitch length may not be implement-
ed 100% (e.g. when sewing thicker fabrics).
In this case, you can slightly increase the percentage of the stitch length
to actually achieve 100% of the entered stitch length.
To adjust the stitch length correction factor:
1. Open the Seam record set display ( p. 99).
2. Determine how many mm of the desired stitch length have actually
3. Calculate the percentage difference between the actual stitch length
4. Add the calculated percentage to 100%.
This result represents the stitch length correction factor.
5. Press the Stl.corr.fac. input field.
An input window appears.
6. Enter the calculated stitch length correction factor, e.g. 110%.
7. Confirm with
Adjusting the thread tension
The mechanical thread tension requires that the values be calculated in
the Thread tension test menu. To set up the electronically regulated
thread tension, a tolerance range is defined for each seam section.
The machine uses the electronic monitor to regulate the thread tension
automatically and ensure that the thread tension remains in the medium
tolerance range. The values required for this regulation are previously
calculated during the teach-in procedure.
To adjust the tolerance range for the mechanical thread tension:
1. Open the Seam record set display ( p. 99).
2. Press the Thread tension min. input field.
An input window appears.
3. Enter the desired lowest thread tension (cN).
4. Confirm with
5. Press the Thread tension max. input field.
An input window appears.
6. Enter the desired highest thread tension (cN).
