2.5.3 Cross-cutter operating modes
Continuous cutting
In "Continuous cutting" mode, the cross cutter works in continuous mode and makes cuts to a
specific cutting length in accordance with the values previously set until the user stops the
cutting process or sets a different cutting length. A dedicated calculation block is available for
calculating the motion profiles for the cutting process. Two basic cams are reserved for
calculating cutting lengths in "Continuous cutting" mode. This ensures that the user can be
calculating a new cutting length in the background whilst continuing to cut to a different cutting
length. Once the new cutting length has been calculated, the corresponding motion cam can be
preselected with the calculated functions and replace the old cutting length as soon as the
current cut has been completed. "Continuous cutting" mode can be both length-controlled and
mark-controlled (see Chapter 2.5.8). You can switch from "Test operation" and "Reject
operation" to "Continuous cutting" mode without first having to stop the system. You must stop
the system first in order to switch to "Continuous cutting" mode from "Asynchronous cross
cutter" mode.
