All parameters that you enter will be accounted for—even if the
standard table prescribes other values. Undercut parameters that are
not defined are automatically calculated from the standard table (see
“DIN 76—undercut parameters” on page 525"):
"Thread pitch FP" is calculated from the diameter X1.
The parameters I, K, W, and R are calculated from FP.
