Pretty sure you are going to find your offset is due to the fact that you are running a min freq of 11Hz so when you have analog ref selected the Unidrive is giving you an output that is scaled from the max frequency not the input. Not exactly the way one would expect it to work by reading the manual but I've seen classics exhibit this behavior when trying to speed match conveyors using the analog output as a repeater. I wouldn't even guarantee you would get the same behavior with an SP as it is kind of an errata
At this point I would determine how your application is using the feedback and see if you can correct or offset the logic in the PLC
