Detailed Explanation Of Selection Of Functions - JUKI SC-922 Engineer's Manual

(9) Detailed explanation of selection of functions

1 1 1 1 1
Selection of the soft-start function (Function setting No. 1)
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.
1
The sewing speed limited by the soft-start function can be changed. (Function setting No. 37)

Material end sensor function (Function setting No. 2 to 4, 76)
This function is possible when the material end sensor is attached.
As for the details, refer to the "8. Example of material end sensor connection.
(Caution) This function is rendered effective only with the CP-18.
Please set up it with a switch on the panel with the other panels.
3 3 3 3 3
Flicker reducing function (Function setting No. 5)
The function reduces flickering of the hand lamp at the start of sewing.
5
(Caution) When the flicker reducing function is set at the "Flicker reducing function is effective," the
startup speed of the sewing machine decreases.
4 4 4 4 4
Bobbin thread counting function (Function setting No. 6)
When the control panel is used, the function subtracts from the predetermined value and indicates the used
amount of bobbin thread.
For the details, refer to the instruction manual for the control panel.
6
(Caution) If "0" is set, the LCD indication on the control panel will go out and the bobbin thread counting
function will be invalid.
5 5 5 5 5
Thread trimming prohibiting function (Function setting No. 9)
This function turns OFF thread trimming solenoid output and wiper solenoid output when thread trimming is
actuated.
(Caution) This function is rendered effective only with the CP-18.
Please set up it with a switch on the panel with the other panels.
By this function, separate sewing material can be spliced and sewn without trimming thread.

Setting of the needle bar stop position when the sewing machine stops (Function setting No. 10)
The position of the needle bar when the pedal is in its neutral position is specified.
1 0
(Caution) If the stop position of the needle bar is set to the highest position, the thread trimming action
will be taken after the needle bar comes down once to the lowest position.
7 7 7 7 7
Panel operating sound (Function setting No. 11)
Whether the panel operation generates sound or not can be selected.
1 1
0 : The function is not selected.
1
1 to 9 : The number of stitches to be sewn under the soft-start mode.
Data setting range
100 to MAX sti/min <10 sti/min>
7 0
(The MAX value differs by machine head.)
0 : Flicker reducing function is ineffective
0
1 : Flicker reducing function is effective
0 : Bobbin thread counting function is not operative.
1
1 : Bobbin thread counting function is operative.
0 : off Thread trimming is operative. (thread can be trimmed).
0
1 : on Thread trimming is inoperative. (thread can not be trimmed).
0 : Down The needle bar stops in the lowest position of its stroke.
0
1 : Up The needle bar stops in the highest position of its stroke.
0 : off Operation confirmation sound is not generated
1
1 : on Operation confirmation sound is generated.
