Description
Function of needle up/down compensating switch on the operation panel
can be changed.
0 : Needle up/down compensation
1 : One stitch compensation
Number of rotation can be compensated.
Be sure to normally use this function with "0".
This function sets the thread trimming motion after DOWN position has
been off by turning handwheel by hand.
0 : Thread trimming after turning handwheel by hand is permitted.
1 : Thread trimming after turning handwheel by hand is prohibited.
This function prevents the sewing machine from the reverse rotation after it
has stopped.
0 : Initial value
1 : Less effective / 9 : Highly effective
This function sets the magnitude of return force of the needle bar before
the retry motion.
1 : Less return force / 15 : High return force
This function sets the suction motion time of the back-tack solenoid.
50 ms to 300 ms
Function of reverse feed stitching on the way
0 : Function of reverse stitching on the way is not operative.
1 : Function of reverse feed stitching on the way is operative.
Number of stitches of reverse feed stitching on the way.
Effective condition of reverse feed stitching on the way
0 : Function is not operative when the sewing machine stops.
1 : Function is operative when the sewing machine stops.
Thread trimming function by reverse feed stitching on the way
0 : Automatic thread trimming function after completion of reverse feed
stitching on the way is not operative.
1 : Automatic thread trimming after completion of reverse feed stitching
on the way is performed.
Lowest speed by pedal
Sewing speed at the start of sewing (soft-start)(The max. value depends
on the number of rotation of the sewing machine head.)
