8. Detailed explanation of selection of functions

1 Selection of the soft-start function (Function setting No. 1)
The needle thread may fal to nterlace wth the bobbn thread at the start of sewng when the sttchng ptch
(sttch length) s small or a thck needle s used. To solve such problem, ths functon (called "soft-start") s
used to lmt the sewng speed, thereby assurng successful formaton of the startng sttches.
1
The sewng speed lmted by the soft-start functon can be changed. (Functon settng No. 37)
3 7 8
2 Material end sensor function (Function setting No. 2 to 4, 76)
Ths functon s possble when the materal end sensor s attached.
"#-15. Connection of the material and sensor" p. 41
For detals, refer to
the materal end sensor.
(Caution) This function is rendered effective only with the CP-18.
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 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 bobbn thread.
For the detals, refer to the nstructon 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 count-
ing function will be invalid.
5 Thread trimming prohibiting function (Function setting No. 9)
Ths functon turns OFF thread trmmng solenod output and wper solenod output when thread trmmng s
actuated.
(Caution) This function is rendered effective only with the CP-18.
By ths functon, separate sewng materal can be splced and sewn wthout trmmng thread.

6 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 Panel operating sound (Function setting No. 11)
Whether the panel operation generates sound or not can be selected.
1 1
0 : The functon s not selected.
0
1 to 9 : The number of sttches to be sewn under the soft-start mode.
Data settng range
0 0
100 to MAX st/mn <10 st/mn> (The MAX value dffers by machne head.)
0 : Flcker reducng functon s neffectve
0
1 : Flcker reducng functon s effectve
1
0 : Bobbn thread countng functon s not operatve.
1 : Bobbn thread countng functon s operatve.
0 : off Thread trmmng s operatve. (thread can be trmmed).
0
1 : on Thread trmmng s noperatve. (thread can not be trmmed).
0 : Down The needle bar stops n the lowest poston of ts 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.
