2.7 Mark-controlled operation
A sensor, e.g. a photoelectric barrier, registers the cutting marks present on the material. This
sensor signal is processed as an interrupt in the inverter and starts the sawing process. This
method is used if there are cutting marks on the material which have to be referred to, e.g.
when using printed materials.
The above diagram shows a mark-controlled flying saw. The start signal for a synchronising
process then is not generated by the length calculator as in the case of length-controlled
operation, but it is directly cut on the material on marks. The marks are read in the drive via
touch probe and the motion process is started, as illustrated above.
