Functional description
The L_CamContactor function block enables cam signal dynamisation, which is usually necessary to compensate for switching delay times of external control devices (valves, relays etc.). During dynamisation, the switch-on and switch-off positions of a cam signal are shifted proportionally to the speed and to the compensating dead time. In modulo measuring systems, the virtual position shift of the cam switching points in the L_CamContactor function block is limited to half a cycle length because, otherwise, clear assignment of the cam signal to the comparison position would not be possible
A new status bit 15 in status code C5529 indicates when the position shift in the modulo measuring system is greater than half the cycle length and the limitation comes into effect. In addition, bit 31 is also set when bit 15 is est (group error).
Applications
Fast rotating machines with modulo measuring systems (e.g. rotary tables, grinding tables, winders, ...)
