Programming
D.3.7 Level 3 special parameters / Functions
Switching photocell for beginning of seam on or
off:
If the photocell that scans the start position of the seam
is switched off, the machine control requires a fixed inser-
tion distance for machine operation. Therefore, switching
off the photocell results in a switch-over to a fixed inser-
tion length (see Fig. 5). This function is directly related to
the photocell correction functions of the service menu.
>
• Press key.
The alternating request of this function switches between
two modes:
Photocell for beginning of seam and fixed insertion di-
stance.
Switching photocell for end of seam on or off:
If the photocell that scans the end position of the seam
is switched off, the machine control requires a fixed point
for the end of the seam to ensure correct machine ope-
ration. Therefore, switching off the photocell results in a
switch-over to a fixed end of seam point. This function is
directly related to the photocell correction functions of the
service menu.
