Cross Cutter
Features of the "Cross Cutter" prepared solution
 Prepared Solution Servo PLC / ECSxA 1.1 EN 2-57
2.5.7 Simple positioning
Users can use the Simple positioning mode to approach any position on the knife drum.
Possible applications involving simple positioning on the cross cutter include approaching the
knife change position or knife idle position. Four modes are available to the user for such
applications:
• Approach target position via shortest route
• Approach target position clockwise
• Approach target position counter clockwise
• Relative positioning
The "Simple positioning" operating mode is not determined by the motion profile (cam) but
follows linear ramps independently of the profile. In this operating mode, a master value entry
and the cam function will have no effect on drive motion.
