Function
The changed cam assignments are not transferred to the NC until a 0/1 signal edge change in
the ACTIVATE CAM/AXIS ASSIGNMENT signal (DB 48 DR0.6). As an acknowledgement of
transfer, the user receives the CAM/AXIS ASSIGNMENT ACTIVATED signal (DB 48 DR1.6).
He must then reset the signal DB48 DR0.6.
