When the sewing speed or stitch pitch is changed, the normal- and reverse-feed stitch needle entry points
may not be aligned at the time of automatic reverse feed stitching.
In such a case, correct the needle entries by changing the ON/OFF timing of the automatic reverse feed
stitching.
In the case the stitch pitch is large and correction of the timing is difficult, it is recommended to decrease the
reverse feed sewing speed or use the temporary stop function at each corner section of the sewing pattern.
Normal- and reverse-feed stitches may need to be adjusted according to the stitch pitch to be used. Refer to
the Engineer's Manual for how to adjust the stitches.

How to align needle entry points of the reverse feed stitching with those of the normal feed stitching
Carry out "correction of the timing of the reverse feed stitching" according to the difference between the
