I know this is an old post, but to save headache of others who have an Atlas Copco, The P0700 should be 5. 

The command source should point to the Elektronikon.

P0700 = 5 -> USS on COM link

in the MicroMaster Parameter list, when P0700 is change to 5 or any values from 1 to 6, it will also change the values in P0703 up to P2236 but not all. Please read manual of Parameter List.

check this link http://ekofiltre.com/MkIV.html

I had a fault Conv.Format Fail 52 every time the compressor is requested to run, the P0700 was set at 2. The Elektronikon was not receiving a feedback and the MM440 was just running at 38hz, it was not increasing speed. 

 HI did u get the solution for above problem...i am facing same problem,

Hello, write what type of compressor it is and the SET number is xxxx-xxxx-xxxx on the inverter.

The correct SET from AlasCopco must always be loaded on the compressor

 Type of compressor is GA 90 and inverter Part number is 6SE6440-2AD24-0BA1 ,Can u explain more on correct SET from Alas Copco , must always be loaded on the compressor.The inverter is using only for cooling fan running purpose. 

you need to change .txt to .dnl

SET says which parameter set should be loaded into the drive.

if it's GA90FF at 400V then the set parameter is SET 9823 3974 12

in the original, but there is the MM420.
