2.3.5 Piece/stitch count setting

In the power-on state, press

+ key to enter piece/stitch count interface. Use the Left/Right key to switch between the piece/stitch count.

2.3.6 Step motor “Zero” calibration

When the machine is on, adjust the needle distance to 5mm, press

the key to enter the user parameter mode, adjust the parameter to P123,

measure with ordinary A4 paper, adjust the parameter to make the continuous needle distance reach the same length;

Note:When entering the interface of parameter P123, the speed will automatically drop to 200rpm. After leaving this interface, the speed

will return to normal.)

2.3.7 Stitch length adjustment setting

When the machine is on, set the needle distance to 5 mm.Button to enter user parameter model, the parameters to P112 (track 1 suture needle

distance compensation), P114 (track 2 stitches distance compensation), P116 (track 3 stitches distance compensation), P118 (track 4 stitches

distance compensation), in ordinary A4 paper paper test, measure distance between two pinhole on the paper,adjust the parameter to stitch 4.9

5.1 mm.Then enter P113 (track 1 reverse stitching distance compensation), P115 (track 2 reverse stitching distance compensation), P117 (track 3

reverse stitching distance compensation), P119 (track 4 reverse stitching distance compensation), use ordinary A4 paper, stitch a section forward,

press and hold the manual reverse stitching switch, adjust the parameters, make the reverse stitching overlap more than 11 stitches.

Note: When entering the P112-P119 interface, the speed will automatically change to 200 RPM for easy debugging. After leaving the interface,

the speed will return to normal.

3 Thin thickness detection parameter model description

3.1 Thin thickness detection function description

For the requirements of over-stalk in the sewing process, when the thickness detection is turned on, when the cloth suddenly thickens, it will slow

down according to the setting, and the needle distance will change to fully over-stalk.

3.2 Thin material thickness setting:

1）Long press the Thin Thickness Test key to enter the Thin Thickness Test Setting Interface, stop the needle to the stop position (the needle plate

with teeth exposed), and place the thinner part of the cloth;

2）Click +/- to select item H01, and long press P to display "H01 ----" on the panel;

3） Wait until the panel displays "OK" and the voice announces "successful identification of fabric thickness". After about 0.8s, "H01-DD-SS" is

displayed (DD stands for real-time height and SS stands for set height). At this time, thin material thickness identification is completed, and the AD

value identified is stored in P25.

pay attention to：If the height of thin material identification is larger than the set value of thick material thickness, it shows that ER is about 0.8S,

indicating that the setting fails;

3.3 Thick material thickness setting:

1) Long press the Thin Thickness Test key to enter the Thin Thickness Test Setting Interface, stop the needle to the stop position (exposed needle

plate with teeth), and place the thicker part of the cloth;

2) Click +/- to select item H02, long press P to display "H02 ----" on the panel;

3）Wait until the panel displays "OK" and the voice announces "successful identification of fabric thickness". After about 0.8s, "H02-DD-SS" will be

displayed (DD stands for real-time height and SS stands for set height). At this time, the thickness identification of thick material is completed, and

the AD value identified is stored in P17.

pay attention to：If the height of thick material identification is smaller than the set value of thin material thickness, it shows that ER is about 0.8S,

indicating that the setting fails.
