5. Production support function
The production support function consists of three different functions (six different modes) such as the production volume management function, operation measuring function and bobbin counter function. Each of them
has its own production support effect. Select the appropriate function (mode) as required.
Production volume management function
■
Target No. of pcs. display mode [F100]
Target/actual No. of pcs difference display mode [F200]
The target number of pieces, actual number of pieces and the difference between the target and actual
number of pieces along with the operation time are displayed to notify the operators of a delay and ad-
vance in real time. Sewing machine operators are allowed to engage sewing while constantly checking
his/her work pace. This helps raise target awareness, thereby increasing productivity. In addition, a delay
in work can be found at an early stage to enable early detection of problems and early implementation of
corrective measures.
Operation measuring function

8. Detailed explanation of selection of functions
Selection of the soft-start function (Function setting No. 1 and 37)
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.
11
The sewing speed limited by the soft-start function can be changed. (Function setting No. 37)
3 7710
Material edge sensor function (function setting Nos. 2 - 4, 76)
2
This function is enabled when the material edge sensor is installed on the sewing machine.
Refer to
(Caution) This function is rendered effective only with the CP-18.
Flicker reducing function (Function setting No. 5)

amount of bobbin thread.
For the details, refer to the instruction manual for the control panel.
61
0 : Bobbin thread counting function is not operative.
1 : Bobbin thread counting function is operative.
(Caution) If “0” is set, the LCD indication on the control panel will go out and the bobbin thread count-
ing function will be invalid.
Thread trimming prohibiting function (Function setting No. 9)
5
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.
By this function, separate sewing material can be spliced and sewn without trimming thread.
90
0 : off Thread trimming is operative. (thread can be trimmed).
1 : on Thread trimming is inoperative. (thread can not be trimmed).
