PPLICATIONS
3.1 On Cut-To-Length Machines
The machine adopts the counter function in CTA and acquires the feedback signal from the encoder for measuring
the actual operation distance. When the set distance is reached, the output signal will enable the knife for the
cutting.
Example: We will simulate the action above by using CTA and Delta ASDA-A.
