(3) Details of a memory switch
① Selection of the soft-start function（U001）
The needle thread may fail to interlace with the bobbin thread at the start of sewing when the stitching
pitch (stitch length) is small or a thick needle is used. To solve such problem, this function (called “soft-
start”) is used to limit the sewing speed, thereby assuring successful formation of the starting stitches.
0 : The function is not selected.
1 to 9 : The number of stitches to be sewn under the soft-start mode.
The sewing speed limited by the soft-start function can be changed. (U037)
Data setting range
100 to MAX sti/min < 10 sti/min >
(The MAX value varies with the machine head.)
② Sewing counting function（U014）
The function counts up every time thread trimming is completed and counts the number of completion of
the sewing process.
1 : on Sewing counting function is operative. (Every time thread trimming is performed)
2 : on External sewing counter switch input.
③ Neutral automatic presser lifting function（U021）
This function can automatically lift the presser foot when the pedal is in the neutral position.
Automatic lifting time of a pedal depends on the lifting time after a thread trimming. When it lowers auto-
matically, it lifts automatically at the second neutral position after deviation from the rst neutral position.
0 : Not provided with the function of automatic presser foot lifting at neutral position of pedal
1 : Provided with selectable function of automatic presser foot lifting at neutral position of pedal
④ Number of rotation of one-shot stitching（U038）
This function can set, by the pedal operation of one time, the sewing speed of one-shot stitching when
the sewing machine continues stitching until completing the number of stitches specied or detecting the
material end.
Setting range : 100 to MAX sti/min < 10 sti/min >
