Cross Cutter
Features of the "Cross Cutter" prepared solution
 Prepared Solution Servo PLC / ECSxA 1.1 EN 2-16
Example:
A position s[units] = 165° needs to be converted into an incremental value. For this example, the
characteristics of the mechanical system are as follows:

TIP!
If you are using the parameterisable variant of the Cross Cutter prepared solution, values in
application units will be converted into incremental values automatically.
The machine parameters can be read from the following display codes using a parameter
setting tool (e.g. GDC or DDS). The machine parameters are set using the
CamManager/CamDesigner software tool (see Chapter 3.4.2). The values displayed in the
codes are read from the profile data associated with the relevant controller (LC9 file):
