9.33.1 Number of Stitches for a Seam with Stitch Counting

Function with or without control panel Parameter

Number of stitches for a seam with stitch counting (Stc) 007

The number of stitches for stitch counting can be set using parameter 007 directly on the control or on a connected

V810/V820 control panel.

can be displayed for approx. 3 seconds. During this time, the value can be varied directly by pressing key +/-.

9.33.2 Stitch Counting Speed

Function with or without control panel Parameter

Positioning speed (n1) 110

Stitch counting speed (n12) 118

Speed control for stitch counting can be selected using parameter 141.

141 = 0 Execution at pedal controlled speed.

141 = 1 Execution at fixed speed n12, when pressing the pedal forward (position >1).

141 = 2 Execution at limited speed n12, when pressing the pedal forward (position >1).

141 = 3 Automatic execution at fixed speed after having pressed the pedal once. The procedure can be interrupted by

“heelback (-2)".

141 = 4 Automatic execution at fixed speed after having pressed the pedal once. The procedure can be interrupted by

“heelback (-2)".
