Distance
Distance from the detection of the sig-
nal to the end of the material.
The distance signifies the path from the
needle to the light barrier. The path is
specified in millimeters and used by the
machine to independently calculate the
number of stitches.
Value range
0 to 255
Signal detection at seam
begin
The signal scan of the light barrier is
performed at the beginning of the seam.
If the function is activated, the light bar-
rier must detect a signal to allow the
machine to sew.
If the function is inactive, sewing can
take place without signal detection.
Value range
On/Off
Signal detection at seam end
The signal scan of the light barrier is
performed at the end of the seam. If the
function is active, the machine will con-
tinue to sew with the specifically set
parameters following the signal detec-
tion. If the function is inactive, nothing
will happen.

Input of the number of signal detections
after which the machine is supposed to
continue with the specifically set param-
eters.
Value range

Filter stitches
Loosely woven fabric with stitches may
cause the light barrier to wrongly detect
a signal. To prevent this from happen-
ing, you enter the number of filter
stitches. This number represents the
minimum number of stitches with signal
detection following the 1
st
detection of
the signal.
