Automatic operation (with reference point on the machine frame)
If a reference point on the machine frame was taken (ref. to „8.7 Measuring from a
Reference Point on the Machine Frame“), the position reference is calculated slightly
different as without reference on the machine frame. Thus automatic operation works as
follows:
•
Start automatic operation with special function
Automatic
(ref. to fig. 16) or digital
input. The control LED
Auto
lights up. Reference position is taken from the actual web
position; when center guiding, reference is taken from the center between the reference
points of the linear units (fig. 20). The controller starts to guide the web to reference
position and to hold this guide point.
•
The reference position can be adjusted during automatic operation with the special
function
Reference
(fig. 16) or using digital inputs (step width 0.1mm). The sensors will
follow the web edge automatically.
•
Quit automatic mode with calling the special function
Automatic
again (fig. 16). The
control LED
Auto
goes off.
Note
Using center guide and web is not running, it can’t be guided properly to the reference
position! The steering frame moves in the limit-of-travel position and may damage the
web. Start automatic mode only when web is slowly running!
