6 Functions and Settings
6.1 First Stitch after Power On
Functions Parameter
1 stitch at positioning speed after power On (Sn1) 231
For the protection of the sewing machine and if parameter 231 is On, the first stitch after power On will be performed at
positioning speed n1, independently of the pedal position and the softstart function.
6.2 Softstart
Functions Parameter
Softstart On/Off (SSt) 134
Functions:
after power on
at the beginning of a new seam
speed pedal controlled and limited to (n6)
lower speed of a parallel function prevailing (e. g. start backtack, stitch counting)
stitch counting synchronized to position 1
suspension with pedal in position 0 (neutral) / interruption by full heelback (position -2)
When using the V820 control panel, direct access is possible by means of the function key (key 9)!
Functions Parameter
Softstart On/Off (-F-) 008 = 1
6.2.1 Softstart Speed
Function with or without control panel Parameter
Softstart speed (n6) 115
6.2.2 Softstart Stitches
Functions Parameter
Number of softstart stitches (SSc) 100
