10. DETAILED EXPLANATION OF SELECTION OF FUNCTIONS
(1)Selection of the soft-start function (Function setting No.1 N-SOFT)
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.
0 : The function is not selected.
1 to 9 : The number of stitches to be sewn under the soft-start mode.
The sewing speed limited by the soft-start function can be changed. (Function setting No.37 S-SOFT)
Data setting range
150 to 5,500 rpm <50 rpm>
(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 effective the function will work.
Setting range
0 to 8
0 : Flicker reducing function does not work.
to
8 : Flickering is effectively reduced.
Reference : 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 in the lowest position of its stroke.
1 : Up The needle bar stops in the highest position of its stroke.
Reference : 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)
This function selects whether the sound is effective or ineffective when operating the four key switches
mounted on the PSC box.
0 : off The sound of click is ineffective.
1 : on The sound of click is effective.
(5)Optional switch function selection (Function setting No.12 SW 2) : It is used only when it
is combined with the machine head provided with the optional switch.
Functions to be assigned to the optional switch can be selected from the following functions.
0 : No function (Standard setting)
1 : Needle up / down compensating stitching : Every time the switch is pressed, normal feed
stitching by half stitch is performed. (Same operation as that of up/down compensating stitching
switch on the panel.)
2 : No function
3 : No function
4 : Thread trimming function : This function is actuated as the thread trimming switch.
5 : Presser foot lifting function : This function is actuated as the foot lifter switch.
6 : One stitch compensating stitch : Every time the switch is pressed, one stitch stitching operation
is executed.
7 : No function
8 : Pedal neutral presser lifting function selection
Do not set to 2, 3, and 7. If these numbers are set, trouble or accident will be caused.
(6)Neutral automatic presser lifting function (with AK device only)
(Function setting No.21 N-NPL)
This function can automatically lift the presser foot when the pedal is in the neutral position.
Automatic lifting time of the pedal depends on the automatic lifting time after thread trimming and when the
presser foot is automatically lowered, it is automatically lifted at the second neutral position after it has come
off the neutral position once.
0 : off Function of neutral automatic presser lifting is not operative.
1 : on Selection of function of neutral automatic presser lifting
