MC_CamIn - Example of "Immediate synchronization"
Synchronization mode:
Relative camming, cyclic mode
With relative synchronism, the Y coordinates of the cam start and end values may
be identical. At the end of a current cam cycle, the cam is added to the current Y
value.
Synchronization condition:
In Mode = 1, the cam is synchronized instantaneously, based on the dynamic
parameters at FB MC_CamIn technology function.
In this example, the leading and following axes are initially moved to their initial
positions by means of positioning commands. Next, the "MC_Camin" function is
started. Synchronism comes into effect instantaneously, because both axes are in
standstill and relative synchronism is requested. (For absolute synchronism, the
slave would first have to be moved to the absolute cam interpolation point that is
assigned to the leading axis.)
