There are some subtle differences between Nord frequency converters from the 500e and 500p series. I.e. changing from 530e to NORDAC PRO 550p needs different register. Unfortunately I had no changelog from the manufacturer.
The reference documents are BU 0500 and BU 0600 respectively.
I found no good way discerning the models apart from reading the parameter 742 = Data base version.
s= Supervisor
P= Parameter Set dependant
Arr = Array Parameter
V = Simple (V)alue, i.e. word/dblword
