6.9.1 Setting the reference position (Parameter 170)
The angular positions necessary on the machine e.g. “needle down position“ or “thread lever up position“ are
stored in the control. A reference position is needed in order to establish a relationship between position
transmitter information and actual mechanical position.
The reference position must be set:

6.9.2 Setting the positions
This is an explanation of terms for the following descriptions:
Position 1 means "Needle lower position"
Position 2 means "Thread lever up" or "Needle rod TDC"
Each position has a starting angle (start) and ending angle (end). The needle stop position always refers to the
starting angle.

The position window 1 and position window 2 must not overlap. Consider that the width of the position window is
at least 30° (difference between start and end of the position)!
If positions are set via the Setting and Putting into Service with the Aid of the Fast Installation Routine (SIR),
then only the starting angle must be set. The end angles are automatically set to 60° after the starting angle.
The needle positions should in principle only be set via the quick installation routine (SIR) to prevent erroneous
inputs. You are guided through the required parameters with it.

Setting and Putting into Service with the
Aid of the Fast Installation Routine (SIR)
It is only important to set the position window including end angle for specific cutting systems. For these
systems, the cutting duration is controlled via the end angle of the position.
