6.7.5.3 Setting the Material thickness detection
parameters
To achieve consistently good sewing results for different material
thicknesses, some parameters can be adjusted specifically to
the material thickness.
Overview of settings modes
The material thickness can be identified in various modes and
responded to depending on the setting. This general explanation
can be applied to the following specific parameters.

Description
In the linear setting, the size of the parameter
increases or decreases steadily as the material
thickness increases. The increase/decrease of the
parameter depends on the limits set for the
minimum and the maximum material thickness.
If a certain material thickness is exceeded, the
nd
2 value of the parameter is activated. If the
material thickness then falls below this level again,
it switches to the base value for the parameter.
If a certain material thickness is exceeded, the
nd
2 value of the parameter is activated. If the
material thickness then falls below this level again,
it does NOT switch to the base value for the
parameter. Only after finishing the seam by cutting
the thread is the base value for the parameter set
again.
