7.4.2 Stitch Counting for Start Backtack/Start Stitch Condensing
Function
with
or
without
control panel
Parameters
Number of stitches forward or without stitch regulator
Number of stitches backward or with stitch regulator
Double start backtack repetition
Backtack repetition On/Off
(c2)
(c1)

The start backtack/start stitch condensing stitches with or without stitch regulator can be programmed and
varied using the above parameters directly on the control or on a connected V810/V820 control panel.
For fast operator information (HIT) when using the V820 control panel, the value of the function switched on
using key
1
can be displayed for approx. 3 seconds. During this time, the value can be varied directly by
pressing key
+
or
-
.
7.4.3 Stitch Correction and Speed Release
Function
with
or
without
control panel
Parameters
Stitch correction time
Delay until speed release after start backtack
(t8)
(t1)
150
200
Speed release after single and double backtack can be influenced by parameter
200.
In the case of slow backtack mechanisms it is possible to delay disabling of the stitch regulator in the single and
double start backtack by the time t8 (start backtack stitch correction) and thereby prolong the backward section.
This time-lag can be selected by means of parameter
150
.
7.4.4 Double start backtack
The forward section will be sewn for a number of stitches that can be set. Then the stitch regulator signal will be
issued and the backward section will be executed. The number of stitches for the two sections can be set
separately.
7.4.5 Single Start Backtack / Start Stitch Condensing
The stitch regulator signal will be issued and the backward section and/or start stitch condensing will be
executed for a number of stitches that can be set.
