Thread trimming in the lockstitch modes is performed at trimming speed.
When the thread trimmer is off, the drive stops in position 2 at the seam end; it stops in position 1 at the end of
programmed seams.
The thread wiper ON period can be set depending on the selected trimming mode (see chapter "Timing
Diagrams" in the List of Parameters). The delay time (t7) (Parameter
206
) prevents sewing foot lifting before the
thread wiper is in its initial position.
If the thread wiper is not connected, there will be a delay time (tFL) after thread trimming until sewing foot lifting.

7.17.3 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.
7.17.4 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.
