(3) Detailed explanation of selection of functions
1
Selection of the soft-start function (Function setting No.1 N-SoFt)
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.
0 :
The functon s not selected.
1 to 9 : The number of sttches to be sewn under the soft-start mode.
The sewng speed lmted by the soft-start functon can be changed. (Functon settng No.37 S-SOFT)
Data settng range
150 to 5,500 st/mn <50 st/mn>
2
Flicker reducing function (Function setting No.5 t-ACC)
The function reduces flickering of the hand lamp at the start of sewing. The higher the set value increases,
the more effectve the functon wll work.
Settng range
0 to 8
0 : Flcker reducng functon does not work.
to
8 : Flckerng s effectvely reduced.
The more effective the flicker reducing function works (the more the set value is made),
the lower the start-up speed of the sewing machine will become.
3
Setting of the needle bar stop position when the sewing machine stops (Function setting No.10 NPS)
The position of the needle bar when the pedal is in its neutral position is specified.
0 : Down The needle bar stops n the lowest poston of ts stroke.
1 : Up
The needle bar stops n the hghest poston of ts stroke.
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.
4
Sound of click of the key switch mounted on the PSC box (Function setting No.11 SOUND)
Ths functon selects whether the sound s effectve or neffectve when operatng the four key swtches
mounted on the PSC box.
0 : off
The sound of clck s neffectve.
1 : on
The sound of clck s effectve.
