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.
