• Main body : Max. 999 patterns (Max. 50,000 stitches/pattern)
• Media : Max. 999 patterns (Max. 50,000 stitches/pattern)
Used to stop machine operation during a stitching cycle.
Allows a pattern to be enlarged or reduced on the X axis and Y axis independently when
sewing a pattern. Scale : 1% to 400% times (0.1% steps)
Pattern enlargement / reduction can be done by increasing / decreasing either stitch length
or the number of stitches. (Increasing/decreasing stitch length only can be performed when
pattern button is selected.)
200 to 2,800 sti/min (Scale : 100 sti/min steps)

UP/DOWN method (0 to 9,999)
In case of a power interruption, the pattern being used will automatically be stored in
memory.
Using jog keys, a 2nd origin (needle position after a sewing cycle) can be set in the desired
position within the sewing area. The set 2nd origin is also stored in memory.
