093
The catch backtack applies only to the start of the seam if double catch backtack is turned on, not for double
start ornamental backtacks (value 0 = catch backtack off). The catch backtack function is only active if at least
parameter 093 > 0.

060
The function applies if the double end backtack/end ornamental backtack is turned on and parameter 060 > 0.
After the end of the double end backtack, the stitch count set with parameter 060 is sewn backwards again.
Afterwards, the thread trimming process is executed corresponding to the setting of parameter 136.
6.10 Intermediate backtack/Intermediate ornamental backtack
If an external key is pushed on the A/5-33 socket, the backtack solenoid can be turned on at any point in the
seam and during a stop. Depending on the setting of parameter 135 and parameter 287, the corresponding
speed limitation of parameter 288 or 289 is in effect.

Intermediate Backtack:
As long as the key is held down, sewing runs backwards with speed limitation (parameter 289) or with the pedal,
depending on the setting of parameter 287.
In addition, parameter 089 can be used to select whether at the end of the manual backtack, release of the key
immediately removes the speed limit (n11) or it is extended by a stitch count.
089 = 0
Manual backtack without extension of the speed limit
089 = 1...255
Stitch count for extension of the speed limitation after end of the backtack
Intermediate ornamental backtack:
After pressing the appropriate key in the seam, the drive stops in position 1. The backtack solenoid is enabled.
After expiration of the ornamental backtack stop period (parameter 210) and furthermore after the pedal is
pushed forward, the drive runs at the ornamental backtack speed and stitches are counted as long as the key
remains down. The drive stops again in position 1. The backtack solenoid turns off.
