6.8 Start Ornamental Backtack
Functions V810/V820
Number of start ornamental backtack stitches forward (SAv) 080
Number of start ornamental backtack stitches backward (SAr) 081
Ornamental backtack function On/Off (SrS) 135
Ornamental backtack stop time (tSr) 210
Last counted forward section of the start ornamental backtack (Zrv) 215
On/Off
Stop time after the ornamental backtack at the start of the seam (SSL) 217
On/Off
Single start ornamental backtack lefthand arrow above key On Key 1
Double start ornamental backtack righthand arrow above key On
Start ornamental backtack Off both arrows Off
Parameter 112 for the start backtack speed applies to both the standard start backtack and the start ornamental backtack.
In contrast to the standard start backtack the following applies to the start ornamental backtack:
The drive stops for stitch regulator switching.
The stop time can be set.
After the backtack section backward follows a backtack section forward with the same number of stitches as the
backward section according to the setting of parameter 215.
The stop time (parameter 210) after the ornamental backtack can be enabled at the start using parameter 217, on
condition that parameters 135 and 137 are set to “ON”. See also timing diagram in the List of Parameters.
When using the V820 control panel, direct access is possible by means of the function key (key 9)!

Parameter 113 for the end backtack speed applies to both the standard end backtack and the end ornamental backtack.
In contrast to the standard end backtack the following applies to the end ornamental backtack:
The drive stops for stitch regulator switching
The stop time can be set
When using the V820 control panel, direct access is possible by means of the function key (key 9)!
