Rule
In a configuration, the time requirement must remain below the interpolation cycle in
accordance with curve trace A. If it is not possible to alter the number of required NCUs, the
interpolation may have to be adapted if necessary.
If the interpolation cycle has to remain unchanged, the number of NCUs in the lead link axis
grouping may have to be reduced if necessary.
