Connection Scheme for Puller Operation (Pa. 290=9) with Other Controls
Any type of drive
Stepping motor control
Control
The following connections and settings are necessary for puller operation:
§
Puller operation requires the signals generator impulses (G1), position 1 (POS1) or position 2 (POS2) and machine
running (ML) from the sewing machine control to be connected.
§
If the sewing machine is equipped with a backtacking solenoid, the backtacking signal must be connected to input in2 of
the stepping motor control in order to have the puller run in the opposite direction. During stitch condensing on chainstitch
machines the stepping motor speed must be adapted to the stitch length.
Option: Signal puller lifting on socket ST1/27
§
In order that the puller is automatically lifted, the sewing foot lift signal must be connected to input in1 of the stepping
motor control. The puller is lifted together with the sewing foot whenever the function has been switched on by means of
pushbutton 9 on the V820 control panel.
§
Furthermore, the thread trimming signal must be connected to input in6 in order that the puller operation is delayed at the
start of the seam.

Set a window by means of parameter 171. In its angular range intermittent operation is possible. The reference point of this
window is determined at the leading edge by the external position on socket B18/7 of the sewing drive. The number of
stepping motor impulses depends on the setting of parameter 180.
