7.6.3 Chainstitch thread cutter (var. modes)
Thread trimming in the chainstitch modes is performed at machine standstill in position 2.
The signal sequence of M1...M4 and sewing foot lifting at the seam end can be set as desired using parameters
280...288
(Parallel or sequential).
When the thread trimmer is off, the drive stops in position 2 at the seam end.
7.6.4 Chainstitch Machine Trimming Signal Times
Signal delay times and ON periods can be set with the help of the following parameters.
See chapter 8 »Setting the Basic Functions, Selection of Functional Sequences« in this manual for further
information on chain stitch seam end variants and chapter »Timing Diagrams« in the List of Parameters.

There are various setting possibilities with the following parameters in the overlock mode (mode 7).
018 =0
Sequence with stop.
018 =1
Sequence without automatic stop at the seam end. When the comma
nd “run” is given, the drive
runs at the pre-selected speed. The program switches to the next start of a seam without issuing
signals M1/M2, when the pedal is in pos. 0 (neutral) or the light barrier is covered.
018 =2
Sequence as with setting 1. But with pedal in pos. 0 signals M1/M2 will be issued, and the
program switches to the next start of a seam.
018 =3
Sequence as with setting 1. But with pedal -2 signals M1/M2 will be issued, and the program
switches to the next start of a seam. Intermediate stop and sewing foot lifting with pedal in pedal -
1 is possible.
018 =4
If the light barrier is covered during the end count for chain suction, the program switches
immediately to the next start of a seam. If the end count has been completed and the light barrier
remains uncovered, the drive stops immediately.
018 =5
Tape cutting at the start of the seam with stop.
267 =0
Start count cancellation by light barrier uncovered impossible.
267 =1
Start count cancellation by light barrier uncovered.
Chain suction or tape cutting at the start of the seam are cancelled whenever the light barrier
senses “uncovered”, and the seam end will be initiated.
