Generalized solution
In a link grouping with several (up to 8) NCUs, some NCUs are set up with short interpolation
cycles, some with standard interpolation cycles, and the axes are configured as in the
diagram above. The requirements for NCUs can be optimized in this manner. Eccentric
machining is possible for multi-spindle turning machines in conjunction with the axis
container concept (see "Axis container").
Note
There is a second method of specifying the motion of the X axis:
by means of master value coupling of the X axis to the spindle (LEADON). This alternative is
still possible and is sufficient for tasks with low dynamic performance requirements.
However, it does not offer a specific function extension for eccentric turning, and does not
allow setpoints to be specified on an NCU with a faster IPO cycle via an NCU link.
