HEXAGON Probe Head VS RENISHAW

The PH10 cannot rotate to negative A values.

What you are asking, is like asking why, when you go to convert a Blu-Ray disc to VHS, the picture quality doesn't stay the same.  It's simply incompatible hardware.  Frankly, I'm impressed that the software will adapt the 5° increments to the 7.5° increments on its own. 

You would need to comprehensively assess all necessary probe angles currently on your HH-AS6-T5, into probe angle equivalents for the PH10M.  There's no way to automate this conversion.

Any -A values would have to be a positive value (180 out of phase) with B rotating to the same value.

I mean... Maybe you just like VHS and all the BE-KIND-REWIND stickers from that era. 
 
You could manually enter all the data from both machines in excel and have it highlight only valid angles and opposite angles that just need inverted. 
Then see what your left with and if those limitations will work for your situation.
