powerflex 40 multi drive: invalid size connection

I have a problem with 2 powerflex 40 connected via 22-comm-E (multi-drive) with a compactLogix L32 controller. I'm sure I've correctly set all communication parameters (number of nodes, addresses, baudrate , the dip-switch on the card and so on (it's not the first time I have this configuration). In sigle drive mode the 22 comm e works, but in multi drive mode I can see only the port 0 and the drive connected to this. The PORT led is always flashing red and I have the code error 16#0109 invalid connection size. I've check cables and parameters but nothing..........

someone can help?

Solved?

Did you ever solve this issue? I am seeing the same currently.
