I don't. I wrote the file. It simply lists some distances for
constraints used in the dummy atom constructions that pdb2gmx
builds for rotatble groups (e.g. -NH3 groups) with the option
'-dummy'.

Try running grompp with the option '-pp'. That will produce a
file 'processed.top' which contains all the included .itp files
verbatim, as well as the contents of the original .top file.
Have a look at that file, look for a place where it says 'ff_dum',
or else look for a phrase like 'These constraints' (first words
in 'ff_dum.itp') and see if anything appears out of the ordinary.
(Note: If you haven't seen such a file before, it might all appear
incomprehensible.)
