The advanced dialog has already been mentioned
in the section entitled “Use of
the network help program”. The other selection options in this dialog window are
described in the following.
To call up the advanced dialog, simply press the following pushbuttons:

8.5.1. Look Ahead and Timing
The default tab of the advanced dialog contains the Look Ahead and Timing set-
tings.
Look Ahead function
The Look Ahead function configures the logic for “looking ahead” into the next
downstream zone. If this zone is occupied when a load appears in the current
zone, the module dynamically adapts the motor roller speed to the selected
speed. This function is particularly useful in applications with faster speeds in
which a greater braking distance is required. Loads can be prevented from run-
ning past their stop positions in this way.
The function can be used zone-wise or for the entire system.
Figure 37 Normal run before Look Ahead function starts
In figure 37 the conveyor belt is running at the speed that has been configured for
the module by the auto configuration procedure or at a manually entered speed.
