Sub-menu for thread tension
The thread tension values for the ranges in the current seam pattern
are specified here.
Sub-menu for thread tension: The thread tension sub-menu for the
cross-tack seam pattern.
Thread tension in range 1 (linear thread tension)
Thread tension in range 2 (zig-zag thread tension)
Thread tension in range 5 (thread tension at seam end)
Input: 0 100 ,
All values can be set independently from each other.
The adjustable tension values for all additional standard seam patterns
can be taken from the following table.
A maximum of five thread tension ranges can exist for one seam
pattern. At the programming level, another tension value can be
specified for each range. The ranges are defined internally for the
standard seam pattern. They can be programmed as desired for the
free seam contours. The first tension range (1) is available for all types
of seam patterns and also for the free seam contours.
The thread tension can be distinctly adjusted in the individual ranges
only when working with the seam pattern programs. For standard seam
patters, only the thread tension in the first range can be set. The other
ranges are then changed accordingly.
0 = lowest thread tension
100 = highest thread tension
