[Setting the condensation pitch]
❶
1. Select "U281 End condensation pitch for shorter-thread remaining
thread trimming" from "1. Display all".
2. Set the number of stitches.
(Factory-set value 0.3; H type 0.5)
3. Confirm your entry by pressing
❶
. Then, the sewing screen
is displayed.
◦ If the condensation pitch is de
-
creased, the phenomenon where
the needle enters the same needle
entry point will likely to occur, result-
ing in unstable formation of thread
loop at the time of thread trimming.
As a result, thread trimming fault is
likely to occur. It is therefore nec-
essary to adjust the condensation
pitch carefully. (The needle entry
phenomenon differs according to
the material to be sewn and the
needle count, the pitch should be
increased if thread trimming failure
occurs.)
