P24 Position to perform thread
trimming by pedal
The position to perform thread trimming by operating the pedal is
set with this function setting item.
S 30-500 130
P25 Correction of solenoid-on
timing for the reverse feed
stitching at the end of sew-
ing
Stitch alignment can be carried out by changing the timing of
actuating the reverse-feed stitching solenoid at the time of reverse
feed stitching at the end of sewing. When the set value for this
parameter is increased, the length of stitch at the beginning of C
process is increased.
U 0-200 123
P26 Correction of solenoid-o
timing for the reverse feed
stitching at the end of sew-
ing
Stitch alignment can be carried out by changing the timing of
releasing the reverse-feed stitching solenoid at the time of reverse
feed stitching at the end of sewing. When the set value for this pa-
rameter is increased, the length of stitch at the end of C process
is decreased and the length of stitch at the beginning of D process
is increased.

P29 Brake force of the main
shaft at the time of stopping
the sewing machine after
thread trimming
Main shaft brake force is adjusted with this function setting item
for preventing the sewing machine from overrunning before stop-
ping.
S 1-45 30
P32 Correction of solenoid-on
timing for the overlapped
stitching
Stitch alignment can be carried out by changing the timing of actu-
ating the reverse feed stitching solenoid at the time of overlapped
stitching. When the set value for this parameter is increased, the
length of stitch at the end of A (C) process is increased and the
length of stitch at the beginning of B process is decreased.

Stitch alignment can be carried out by changing the timing
of releasing the reverse-feed stitching solenoid at the time of
overlapped stitching. When the set value for this parameter is
increased, the length of stitch at the end of B process is increased
and the length of stitch at the beginning of C process is de-
creased.

P44 Brake force of the main
shaft at the time of stopping
the sewing machine on the
way
Main shaft brake force is adjusted with this function setting item
for preventing the sewing machine from overrunning before stop-
ping on the way.

P45 ON duty of the reverse feed
stitching solenoid
Output duty of the reverse feed stitching solenoid when the sole-
noid is in the ON state is set with this function setting item.

P46 Setting of the function of
reverse revolution to lift the
needle
This function rotates the main shaft in the reverse direction of
sewing to bring the needle bar to the highest position.
ON: Reverse-revolution operation is in the ON state
OFF: Reverse-revolution operation is in the OFF state
U ON/OFF OFF
P47 Reverse revolution angle to
lift the needle
The operating angle of the reverse-revolution to lift the needle is
adjusted with this function setting item.

P50 2nd thread trimming speed Sewing speed is decreased in the latter half of thread trimming
operation. That sewing speed is set with this function setting item.

P52 Time to wait for sewing after
lowering the presser foot
The time to wait for starting sewing after the presser foot is low-
ered is set with this function setting item.

P53 Setting of operation of the
presser foot when the back
part of pedal is depressed
The operation of the presser foot when the back part of pedal is
depressed is set with this function setting item.
0: Presser foot does not operate even when the back part of
pedal is depressed.
1: Presser foot goes up to the 1st presser-foot lifting position
when the back part of pedal is depressed by half of the depth.
It goes up to the 2nd presser-foot lifting position when the
back part of the pedal is further depressed.
2: Presser foot does not operate even when the back part of
pedal is depressed. It goes up to the 2nd presser-foot lifting
position when the back part of the pedal is further depressed.

needle-up stop angle
The current main shaft angle is always displayed in the data
display section. When you turn the pulley to bring the main shaft
to the needle-up stop position and press the enter switch, the
needle-up angle and needle-down angle of the main shaft are
automatically set.

＊
Do not change the set values with asterisk (*) mark as they are functions for maintenance. If the standard set value set at the time
of delivery is changed, it is in danger of causing the machine to be broken or the performance to be deteriorated. If it is necessary to
change the set value, please purchase the Engineer’s Manual and follow the instructions.
