9.34 Free Seam and Seam with Light Barrier
Function with or without control panel Parameter
Positioning speed (n1) 110
Upper limit of maximum speed (n2) 111
Limited speed according to setting of 142 (n12) 118
Lower limit of maximum speed (n2_) 121
Speed mode free seam (SFn) 142
Speed control for the free seam and the seam with stitch counting can be selected using the speed mode.
142 = 0 Execution at pedal controlled speed
142 = 1 Execution at fixed speed n12, when pressing the pedal forward (position >1)
142 = 2 Execution at limited speed n12, when pressing the pedal forward (position >1)
141 = 3 Only for the seam with light barrier:
- Automatic execution at fixed speed after having pressed the pedal once.
- The seam end is initiated by light barrier.
- The procedure can be interrupted by heelback (-2).
- If the light barrier is not on, speed as with parameter setting 142 = 0.
When using a control panel, the maximum speed is displayed after power on and thread trimming and can be varied
directly using the +/- keys on the control panel. The setting range lies between the values of parameters 111 and 121.
9.35 Light Barrier
Function with or without control panel Parameter
Light barrier On/Off 009
Function with control panel V820
Light barrier covered/uncovered On right-hand arrow above key On Key 3
Light barrier uncovered/covered On left-hand arrow above key On
Light barrier Off both arrows Off
The light barrier function at the input of socket B18/5 is active only if parameter 239 = 0.

Light barrier sensing uncovered/covered (LSd) 131
Start of sewing blocked/unblocked with light barrier uncovered (LSS) 132
Light barrier seam end with thread trimming On/Off (LSE) 133
Speed of the light barrier compensating stitches (PLS) 192
