Hello,

I have an Atlas Copco GA30VSD with a Micomaster 440 (6SE6440-2AD33-7EA1) with Cubicle # 9820-3596-1600.

Back story, we had a wire come loose in the motor connection box and short out the brake controller in the VFD. The VFD was repaired and tested. We hooked it back up on the machine and our Elektronikon is giving us an error of Compressor Motor Converter Format Fail 52.

Here are the current set points on the parameters that I think switch the VFD to remote control.

P0700=2

P719=1-11

P731=52.3

P1000=2

I tried changing P0700=5 with the same results. I am out of ideas at this point does anyone have a complete parameter list for this unit?

hi,

write what the SET parameter is there

I apologize I am not sure I understand. 

What the set parameter is at P0700?  Currently it is 5, when we received the MM440 back it was set to 2.

Or are you saying to set the Parameters on the Elektronikon again? That are outlined in the Atlas Copco Stationary Air Compressors GA18, -30, -37, -45, -50, -55, -75, -90 (W) VSD User manual for Elektronikon® II regulator. 

hi

so try it
