11) Change the setting of bits from 6 to 8 of the SW504 depending
on the clearance. Refer to the table below.
* When the adjustment width is 0:
Since the stitch position is aligned with the folding position,
the setting is not changed.

Subtract the distance from the value on the above figure,
and set the obtained value to SW504.
