2.1 Brief description
Essential features
● Cross-NCU interpolation of fast (X) and standard (C,Z) axes/spindles (see diagram).
● The part program is running on the NCU with the faster interpolation cycle and can "see"
● Communication between the NCUs takes place via the link modules in the cycle of the
● The slower interpolation cycle is an integer multiple of the faster interpolation cycle.
● Due to the different cycle clocks used, it is necessary to comply with the supplementary
● Contour accuracy between the faster and slower interpolating axes is ensured provided
