Problems redefining DVAL when UEIP=Yes

[kmpeters]

If a motor has the following setup:

• MRES != ERES
• UEIP = Yes
• FOFF = Frozen
• SET = Set

And the DVAL is redefined, the DVAL will be calculated based on the MRES, instead of the ERES, resulting in the wrong position being sent to the controller.

This problem was encountered during testing of an OMS MXA prototype with a BiSS-C encoder. I don't think this problem is driver-specific, but I could be mistaken.
