Tape cutter function when output M6 is disabled:
 At the start of the seam, the tape cutter will be activated for the time (kt4) after a number of stitches (c7) that can be set
by means of parameter 257.
 After light barrier sensing, the tape cutter will be activated for the time (kt4) at the seam end after a number of stitches
(c8) that can be set by means of parameter 258.
 At standstill of the drive the tape cutter operation (double tape cutting) can be repeated any number of times by
pressing the key (setting parameter 244 = 15) connected to socket ST2/5.
See also chapter “Timing Diagrams“ in the List of Parameters.
9.29.4 Tape Cutter/Fast Scissors in Mode 16
Function without control panel Parameter
Count c1 On/Off LED 1/2 Key S2
Counts c3 and c4 On/Off LED 3/4 Key S3
Functions of sewing foot lifting On/Off LED 5/6 Key S4
Basic position 1 or 2 LED 7/8 Key S5
 The signal tape cutter/fast scissors can be set separately for start and end counting.
 The V810 control panel cannot be used if parameter 290 = 16 (mode 16).
 When using the V820 control panel, parameter 292 will automatically be set to slide-in strip "7" if 290 = 16.
