3.7 Programming of Seams
Um häufig vorkommende Nähabläufe komfortabel einstellen und abrufen bzw. verschiedene Nähte mit unterschiedlichen
Einstellungen aneinanderreihen zu können, ist die Naht-Programmierung möglich.
 A maximum of 8 patterns with a total of 40 seams can be established.
 Programming is possible only if a code number has not been input after powering on!
 The functions “start backtack”, “end backtack”, “stitch counting”, “thread trimming” and “sewing foot lift” can
be assigned individually to each seam.
 For all 8 patterns, different numbers of start and end backtacking stitches can be programmed.
 The maximum number of stitches for the forward or backward section is limited to 15 stitches.
 It is possible to “teach in” seams with stitch counting by executing the desired sections.
Example 1: Pattern 1 40 seams Example 3: Pattern 1 10 seams
Pattern 2-8 0 seams Pattern 2 15 seams
Example 2: Pattern 1 4 seams Pattern 3-8 0 seams
Pattern 2 5 seams
Pattern 3 6 seams
Pattern 4 25 seams
Pattern 5-8 0 seams
Examples 1 and 2 show that optimal utilization of the storage capacity is possible.

When sewing backward, all sewing operations including backtack are performed in reverse feeding direction. The functions
"light barrier seam" and "backward seam" block each other, i.e. the light barrier cannot be enabled if the backward seam
has been selected, or, backward sewing is not possible if the light barrier is enabled.
Change the number of stitches using the +/- keys,
or execute the seam section using the pedal !

Changing the number of compensating stitches
If stitch counting and light barrier are to be On at the same time, the number of stitches for a seam with counting must be
programmed before the light barrier compensating stitches.
After programming the functions
Seam is entered; 
the next seam is displayed.
The seam is entered by pressing key E or by heelback.
End of programming !
The first seam section to be executed 
in the selected pattern is displayed.
After all seams have been programmed, each seam can be called again with the Ekey for checking.
Note
Several seam patterns cannot be programmed successively without interruption. Each pattern must be completed with
the P key; otherwise it gets lost.
Note
The patterns are permanently saved only after you have started sewing.
3.7.5 Detailed Example
A seam 1 with stitch counting and double start backtack, a seam 2 with stitch counting and a seam 3 with light barrier, end
backtack and thread trimmer are to be programmed under pattern number 4.

3.7.6 Maximum Number of Seams Exceeded
If by inputting a program the total number of 40 seams is exceeded, the teach-in mode cannot be completed by pressing the
Pkey. A new start of sewing is impaired. The display shows a warning (dEL). By pressing the Pkey again the pattern
displayed will be deleted. Exit the teach-in mode now if the total number of 40 seams is not exceeded. Otherwise there will
be a new warning.
Display:
X: Last input or selected pattern number (1...8)
YY: Number of programmed seams of the selected 
pattern (0...40)
NN: Total number of input seams if more than 40
The user must now decide which pattern should be deleted !
Selection of the pattern to be deleted 
X: Pattern number
YY: Number of seams of this pattern
NN: Total number of input seams if more than 40

X: Pattern number of the deleted pattern
YY: 00 = no more seam is programmed
NN: Total number of input seams if more than 40
Exit the teach-in mode if the number of seams equals or falls below 40, and the last input seam will be displayed.

Parameter 275 = 1 Seam suppression enabled: i. e. if the light barrier is Off and stitch counting is set at 0 stitches, the
program switches to the next seam if the function is On. In case functions such as start of end
backtack, thread trimmer, are On, they will be performed before switching to the next seam.
Functions Parameter
Correction seam On/Off, seam or pattern interruption by thread trimmer (dkn) 276
Parameter 276 = 0 Correction seam disabled: The seam can be interrupted by pressing the pedal to pos. –2. The control
switches automatically to the next seam number.
Parameter 276 = 1 Correction seam enabled:
- The seam can be interrupted by pressing the pedal to pos. –2 and thread trimming, and a correction
seam (free seam) can be performed manually.
- The correction seam can be completed by pressing the pedal to pos. –2 or by light barrier if it is
On. Then the control switches automatically to the next seam number.
Parameter 276 = 2 Seam or pattern interruption by thread trimming:
- The seam can be interrupted by pressing the pedal to pos. –2 and thread trimming, even if the
thread trimmer is Off. Then the program switches back to the first seam of the selected pattern.
Functions Parameter
Selector: Switch from one seam or pattern to the next (nFS) 277
■Parameter 277 = 0 Switching from one seam to the next is active.
■Parameter 277 = 1 Switching from one pattern to the next is active.
