The AxisBuf functions are needed when multiple short CAM motion tasks are to be joined and the program cannot ensure that the cams are joined fast enough. In this case, the number of preparation buffers can be increased (FC_AxisBufSetMaxEntries) so that multiple process tasks in the program can be triggered one after the other. The system processes the preparation buffers (real-time process). If you modify the number of preparation buffers (default value = 1), set it back to the default value before opening function blocks such as the PacDriveLib (VarioCam-Lib) as these function blocks assume the default value. The program can become simpler for "rigid" courses of the cams that are composed of several component cams using multiple preparation buffers.
