6.16.1 Machine Start Blockage (Blockage 1 and 2)
If the input “machine run blockage“ is activated at machine standstill, the run of the drive is blocked despite pressing the
pedal. Machine start is possible only after deactivating the input.
6.16.2 Function “Machine Run Blockage” 1 (Safety Function) Parameter 283 = 1
In the start backtack:
Fastest stop without positioning. The start backtack will be interrupted.
Trimming is impossible.
After deactivating the machine run blockage the start backtack and the seam will be continued by pressing the pedal to
position >1, or thread trimming will be initiated by full heelback (–2).
In the free seam:
Fastest stop without positioning.
Trimming is impossible.
After deactivating the machine run blockage the seam will be continued by pressing the pedal to position >1, or thread
trimming will be initiated by full heelback (–2).
During stitch counting:
Fastest stop without positioning. Stitch counting will be interrupted.
Trimming is impossible.
After deactivating the machine run blockage stitch counting will be continued by pressing the pedal to position >1, or
thread trimming will be initiated by full heelback (–2).
During the light barrier compensating stitches:
Fastest stop without positioning. The light barrier compensating stitches will be interrupted.
Trimming is impossible.
After deactivating the machine run blockage the light barrier compensating stitches will be continued by pressing the
pedal to position >1, or thread trimming will be initiated by full heelback (–2).
In the end backtack:
Fastest stop without positioning. The end backtack will be interrupted.
Trimming is impossible.
After deactivating the machine run blockage the end backtack will be continued by pressing the pedal to position >1,
or thread trimming will be initiated by full heelback (–2).
6.16.3 Function “Machine Run Blockage” 2 (Control Function) Parameter 283 = 2
In the start backtack, during stitch counting and the light barrier compensating stitches:
Stop in the selected position.
Trimming without end backtack by full heelback is possible when machine run blockage is On. In this case, a new
seam will be started after deactivating machine run blockage.
After deactivating the machine run blockage the start backtack or stitch counting will be continued by pressing the
pedal to position >1, or thread trimming will be initiated by full heelback (–2).
In the free seam:
Stop in the selected position.
Trimming without end backtack by full heelback is possible when machine run blockage is On. In this case, a new
seam will be started after deactivating machine run blockage.
After deactivating the machine run blockage the seam will be continued by pressing the pedal to position >1, or thread
trimming will be initiated by full heelback (–2).
In the end backtack:
The end backtack will be completed with a stop in the selected position. The start of the next seam is blocked.
Trimming by full heelback is possible when machine run blockage is On.
After deactivating the machine run blockage the sewing operation will be completed by thread trimming by half
heelback, unless the thread has been trimmed before.
If the thread is trimmed when machine run blockage is On, a new seam will be started after deactivating the machine
run blockage.
During thread trimming:
Thread trimming will be completed. The start of the next seam is blocked.
After deactivating the machine run blockage the start of the next seam is possible.
