5-4-2. Setting the length of the hole
Set parameter number 02 to the length of the hole that matches the cutter being used.
Be sure to change the setting for the length of the hole if the cutter is replaced with a cutter of a different length.
The stitch length will be automatically determined by the value for the length of the hole which has been set. Therefore, if the
length is not set correctly, problems may occur, such as the bar tacking areas being cut by the cutter.
5-4-3. Buttonhole sewing size
A. Length of the hole (Parameter No.02)
B. Zigzag width (Parameter No.08)
C. Cutter X space (Parameter No.04)
D. Cutter Y space (Parameter No.05)
E. Front tack length (Parameter No.18)
F. Rear tack length (Parameter No.25)
G. Zigzag stitch length (A + D + D) *
H. Bar tack width (B + B + C) *
I. Buttonhole length (A + D + D + E + F) *
* Set automatically.
5-4-4. Main restrictions when setting parameters
When the sewing area is set to 4.0 x 32.0 mm (default setting)
Symptom Cause
Parameter number 08
(Zigzag width) does not
become larger.
If the sewing area is 4.0 mm and parameter number 04
(Cutter X space) is set to 0.2 mm, the zigzag width that
can be entered will be limited to (4.0 - 0.2)
2 = 1.9
mm.
Parameter number 04
(Cutter X space) does not
become larger.
If the sewing area is 4.0 mm and parameter number 08
(Zigzag width) is set to 1.8 mm, the cutter X space that
can be entered will be limited to 4.0 - (1.8 + 1.8) = 0.4
mm.
Parameter number 29
(Eyelet buttonhole radius)
does not become larger or
smaller.
If the sewing area is 4.0 mm and parameter number 04
(Cutter X space) is set to 0.2 mm and parameter
number 08 (Zigzag width) is set to 1.5 mm, the eyelet
buttonhole radius that can be entered will be a minimum
of (1.5 + 1.5 + 0.2)
2 = 1.6 mm, and a maximum of 4.0
2 = 2.0 mm.
