12.13.2 Backtack
12.13.2.1 Start backtack
Pre-control angle when switching on the backtack magnet.
(Switchover of forward backward at the bartack)
Pre-control angle when turning the backtack magnet off. (Changing of
backward forward at the bartack)
Initial backtack with the position 0 of the pedal interruptible.
0 =
off;
1 =
on
Mode for the end of the initial backtack.
0 =
You sew further after the end;
1 =
Machine stops and must be started by the pedal again;
2 =
Thread performance after the initial backtack
Pedal release only to an additional route A
0 =
off;
1 =
on
Delay time up to the speed release after the initial backtack
The initial interlock starts when the pedal is pushed forward at the start of the seam. With the foot raised the
interlock is delayed by time t (parameter t 03 10 start up delay after switching off the sewing foot raising signal).
The initial interlock runs automatically at speed n (parameter t 00 00). If a soft start is running at the same time
the lower speed takes priority. Parameter t 00 03 specifies whether it is permitted to interrupt the initial interlock.
The parameter has no effect on a fancy stitch interlock. Parameter t 00 03 = 0 The interlocks run automatically
and cannot be interrupted. Parameter t 00 03 = 1 The interlocks can be stopped by putting the pedal in the 0
position.
Counting and switching the reverse feed lever on and off are synchronized at the "needle down" position. When the
reverse run is finished, the different modes from the end of the initial interlock are set with parameter t 00 04 .
Parameter t 00 05 restricts the speed for another run A to the initial interlock speed. ( parameter t 00 00)
12.13.2.1.1 Correcting stitch pattern
Pre-control angle when switching on the backtack magnet.
(Switchover of forward backward at the bartack)
Pre-control angle when turning the backtack magnet off. (Changing of
backward forward at the bartack)
