Objects Mapped To Parameters That May Not Exist In A Unidrive M
When in Unidrive SP override, the following parameters will be available (via the CoE object
mapping mechanism) that may or may not exist on the drive (depending on the model). If they do
exist, reading and writing work as expected. If they do not exist, a write will succeed, and a read will
return zero.

Objects Redirected To Other Parameters
When in Unidrive SP override, the following Unidrive SP parameters will be available (via the CoE
object mapping mechanism) that map to different parameters on the drive. If they do exist, reading
and writing work as expected. If they do not exist, a write will succeed, and a read will return zero.

Objects That Require Additional Configuration To Work As Expected For Unidrive SP
When in Unidrive SP override, the Run time (years/days/hours/minutes) will only return valid values
if the Unidrive M Date/Time Selector (Pr 06.019 is set to Running (2)).
Objects Values That Are Correctly Scaled To Be Same As Unidrive SP
When in Unidrive SP override, the resolution and size of some on the objects are different to that for
Unidrive M, so a conversion function is invoked when reading and writing to the corresponding
objects.
It must be noted that there may be a loss of accuracy and possible rounding errors. The effected
objects (if the corresponding parameter exists) are as follows:

0x30003
0x40003
