Stitch length adjustment forwards and in reverse
Requirement
At a maximum speed of 400 spm, the stitch length selected on the control panel should not
differ from the actual stitch length when sewing forwards or in reverse.
●
Thread the machine.
●
Switch on the machine.
●
Select the stitch length being used on the control panel.
●
With parameter
607
limit the maximum speed to 400 spm.
●
Set parameter
846
at
100.
●
Place the workpiece under the presser foot.
●
Sew a seam with at least 20 stitches.
●
Measure the length of the seam over 20 stitches and calculate the actual stitch length.
●
If the difference, measured over 20 stitches, is larger than +/- 0.5 mm, the value for
parameter 846 must be corrected.
●
Take the value for parameter
846
from the table or calculate it with the aid of the formula:
●
Select the calculated value for parameter
846
and switch off the machine.
The adjustment of the reverse stitch length is carried out as described in the
above work steps under parameter "847
"
, with the reverse feed key pressed,
see
Chapter 7.02 Keys on the machine head.
More information about selecting
and changing parameters and explanations (functions) of the individual
parameters is contained in
Chapter 13.11 Parameter settings.
