parameter
Setting options
Material thickness detection active/inactive.
Tolerance at which the material thickness detection based on
whether
the second stitch length, the second needle thread tension and/or
the second sewing foot stroke switches back. This tolerance is
designed to ensure that there is no constant alternating between
activation and deactivation in the boundary range.
(Value range 0.0 – 2.0 [mm])
With extremely thick material, the foot pressure increases above the
standard set value due to the thickness of the material. To a certain
extent, the machine can compensate itself for the influence of thick
material.
(Value range On/Off)
(SpeedCorr) parameter
Setting options
Tolerance at which the correction of the effects of high speeds based
on whether the second stitch length, the second needle thread tension
and/or the second sewing foot stroke switches back. This tolerance is
