Intermediate ornamental backtack (parameter 135 = 1) with counted backtack section
(parameter 087 = >0):
After pressing the appropriate key, the drive stops in position 1. The backtack solenoid is enabled. After the
ornamental backtack stop time (parameter 210) has elapsed and the pedal has been pressed forward, the drive
runs until counting (parameter 087) has been completed. The drive stops again in position 1. The backtack
solenoid is disabled, and the time set using parameter 210 elapses. Then the seam section forward is repeated.
The sequence is performed at speed n9 (parameter 122).

In this type of backtack, the parameters
070...073
are used to enter unequal numbers of forward and backward
stitches (e.g. forward 3, backward 2).
In addition, parameters
090 and 091
are used to enter the number of repetitions of the forward and backward
sections (e.g. 3).
The first backward section of the start multiple backtack is carried out with the same number of stitches as the
forward section.
The last forward section of the end multiple backtack is carried out with the same number of stitches as the
backward section.
074 = 1
Execution type of start multiple backtack as flying backtack
074 = 2
Execution type of start multiple backtack as ornamental backtack
075 = 1
Execution type of end multiple backtack as flying backtack
075 = 2
Execution type of end multiple backtack as ornamental backtack
The multiple backtack function is enabled by pressing a key assigned to the input function described in
parameter
240 = 95
(e.g. parameter
842 =95)
.
7.4.9 Stitch lock at the seam end
Function
with
or
without
control panel
Parameter
Number of stitch locks
Start delay in stitch locks
(KSt)
(tKS)
093
094
The stitch lock function at the end of the seam is enabled with parameter
093
. It is carried out on the end of the
seam after the
start delay (
parameter
094
) completes.
093 = 0
Function Off
093 = >0
Function on. The configured value corresponds to the number of stitch locks
7.4.10 Stitch Regulator Suppression/Recall
Effective in standard and ornamental backtack
The next backtack and/or stitch condensing operation can be suppressed or recalled once by pressing an
external key according to the pre-selection of parameters
240...249
.
